Carbon nanotube has been discovered by Iijima in 1991 (Iijima, 1991). Then Iijima set up that Carbon nanotube exist in two coordinates single-walled (SWNTs) and multi-walled (MWNTs) century nanotube (Iijima Ichihashi, 1993). Typically multi-walled ascorbic acid nanotube typeset of joined single-walled vitamin C copy nanotube. prevalent CNTs subtraction methods include arc run down, laser ablation, and chemical dehyd balancen deposition (CVD). These methods share the s ame principles either carbon atoms de destinationined from fast(a) carbon sources (such as graphite rods usance in arc discharge and laser ablation methods) or carbon-bearing gases (such as hydrocarbons, CO, and volatile solvents in the CVD method). Among these, CVD is the roughly convenient method to grow all kinds of CNTs and the best choice to sustain large amount of CNTs at relatively low cost and with indulgent process conditions(Prasek et al., 2011).In chemical vapor deposition, energy is donated to hydrocarbons to break them into reactive radical objects in the temperature range approximately from 500-800C, sometimes more. These reactive species dispel down to a catalyst surface where they remain bonded. As a result, CNTs are course of studyed. The commonly used energy source is resistive heating(Magrez et al., 2010).It is kind of clear a fewer years ago that the effective catalysts for CNTs deduction are Fe, Co, Ni and their alloys. These catalysts can Growth CNT s in three move according to Vapor-Liquid-Solid (VLS) mechanism Firstly, a gas precursor produces carbons which adsorb and break up on the surface of the catalyst particles to form elementary carbon atoms. Secondly, the carbon atoms dissolve in the mass of the nanoparticles to form liquid metastable carbide and dissipate within the particles. Lastly, solid carbons precipitate at the outer side of the nanoparticles to form carbon nanotubes.Problem statementsCarbon nanotube is one of the most aspirant candidates among all the nanoforms of carbon. However, all the carbon based nanomaterials are synthesized using carbon precursors derived from crude oil sources. It is the required to develop and design techniques that have used ware oils to minimize depletion of petroleum. Few waste oil based precursors have already been successfully used to synthesize multiwalled carbon nanotube (MWCNT) via various techniques. Among them CVD seems to be most appropriate. A CVD system with provisi on for controlling the input parameters by capable mechanism is employ for this. In other hand, it may be noted that non renewable precursors consist of a mixture of a number of hydrocarbon molecules. This makes the optimization move for tax deduction of CNTs from non renewable precursors highly demanding. The optimization process is complemented by characterization of the CNTs synthesized under different conditions. Characterization of CNTs helps in ascertaining acknowledgement of their uniqueness and suitability to different applications. It is expected that only a few of them go out satisfy the requirements for a particular application. One of the main targets of the ascertain is to demonstrate the applicability of these CNTs synthesized from waste oil precursors for functionalization technique to be suitable for numerous applications.ObjectiveConsidering the environmental effects and depletion petroleum product sources, our efforts will direct to receive waste engine oi l and use it for synthesis carbon nanotubes. Therefore, as a first step, it is attempted to design unclouded and suitable laboratory refining process for waste engine oil to receive quantity of fractions. This outlines the first accusive of the project.The second objective is that gestate utilizing CNTs from the selected waste engine oil precursors.The third objective of the project is to optimise the CNTs synthesis parameters such as temperature, flow rate, precursor type used, and catalysis type.The fourth objective is presenting a thermodynamic study for CNTs.The final objective of the thesis is to demonstrate the ability of MWCNTs synthesized from waste oil precursors for functionalization and study its sprinkle in appropriate liquids.Literature reviewLiquefied petroleum gas, has been employed as carbon source to produce CNT arrays on ceramic world-wide surface in the floating catalyst process into two-stage furnace. Good coincidence of CNT has been obtained and the purit y is as high as 97.5%. Through controlling the growth temperature, CNTs in aligned form with diameter approximately of 13 nm have been gained. As a result, from synthesize industrial fuel as a carbon source and the ceramic substrate, CNT arrays can be soft produced with large scale and at low cost(Zhang et al., 2007).Multi walled carbon nanotubes were utilized by spray pyrolysis of biodiesel oil which prepared from Jatropha curcas over Fe/Co/Mo catalyst which supported on either silica or alumina. Synthesized MWNTs have been characterized by high-resolution transmission negatron microscopy, examine electron microscopy, and Raman spectroscopy. The Raman spectroscopy suggested that the MWNTs were well graphitized. In addition, abundant MWNTs have been utilized by catalyst which supported on silica nanoparticles(Karthi drawan Mahalingam, 2010).Carbon nanotubes were synthesized from heavy petroleum fractions such as Light diesel Oil (L.D.O.) and furnace Oil (F.O.) by modified chemica l vapour deposition method and characterized by transmittance Electron Microscopy and Scanning Electron Microscopy. In this search a topically reactor has been designed for the synthesis and collection of erotica from the petroleum material. Then, the soot collected is purified by sohxlet extraction apparatus. After that, the purified CNTs are oxidized with diluted nitric acid. The utilized CNTs have been outspread in different solvents. Then, the dispersed stability has been analyzed at different temperature and results demonstrates that it is highly disperses in distilled urine and acetone in compared to ethanol and methanol. Result shows SWCNTs having approximately 70nm in term of F.O and 90nm in term of L.D.O (Jagdeep et al., 2011).Single walled carbon nanotubes were utilized by a chemical vapor deposition (CVD) method using heavy oil residue as carbon source. Different kinds of metals as catalysts including transition metals (Fe, Co and Ni) and nonmagnetic metals (Au and P t) are used in the growth of SWNTs. The morphology and structure of the synthesized SWNTs products have been characterized by Raman spectroscopy, atomic force microscopy, transmission electron microscopy, and scanning electron microscopy. The results demonstrated that it is possible to synthesize high quality SWNTs by a CVD method with inexpensive heavy oil residue as the starting material. The diameter distribution of as-grown SWNTs strongly depends on the type of catalysts. It is assemble that SWNTs grown from transition metals (Fe, Co and Ni) have smaller diameter compared to that of SWNTs synthesized from nonmagnetic catalysts (Au, Pt). This result demonstrates the feasibility of controlling the SWNT diameters by selecting the catalysts. Moreover, it is found that the reaction temperature is the key factor that affects the formation of SWNTs from oil residue. In our case, the growth mechanism of SWNTs is considered to be different from that of SWNTs synthesized from conventiona l carbon source (Li et al., 2012).Quasi aligned carbon nanotubes have been synthesized for using waste engine oil (WEO) as the carbon source by thermal chemical vapour deposition. The rich carbon content of WEO was supposed to endorse the growth of the quasi aligned CNTs. deduction process has been carried out at temperature of 500 and 570 C for precursor and CNTs synthesis, respectively, a ferrocene catalyst concentration was 17.99 wt%. Synthesized CNTs have been characterized by energy dispersive X-Ray, roentgen ray diffraction, electron microscopy, and micro Raman spectroscopy. The ability of CNT samples for emitting electrons has been examined by field electron firing off (FEE) analysis. Both Electron microscopy and micro Raman analysis exposed a sullen mixture of quasi aligned SWNTs and MWNTs with a moderate ID/IG ratio of 0.90(Suriani et al., 2015).HypothesisIn this project, we hypothesize that malty walled carbon nanotubes can be a great deal formed by using waste engine oil as non-renewable source. Catalytic CVD will be installed since it is currently considered as the most all-mains(prenominal) and affordable method for growing carbon nanotubes especially with high molecular(a) weight hydrocarbons. Waste engine oil can be used directly into CVD, but it will produce carbon nano materials, which means more impurities such as amorphous carbon, nano fictitious character, and graphite. Thus, we can use re-refine the waste engine oil process at laboratory to receive many hydrocarbon products and use them as a carbon sources.ReferencesChen, T., Qiu, L., Cai, Z., Gong, F., Yang, Z., Wang, Z., Peng, H.
