Catalytic Conversion From Plastic Waste by Silica-Alumina-Ceramic Catalyst to Produce an Alternative Fuel Hydrocarbon Fraction

Liquid fuels from polypropylene plastic waste have been successfully performed by catalytic cracking method. The catalyst used is Al-MCM-41- Ceramics. The catalyst was characterized by XRD, SEM, Pyridine-FTIR, N2-Adsorption-Desorption, and the product of catalytic cracking were investigated by gas chromatography-mass spectroscopy (GC-MS). The catalyst was using three times at sample notify A,B and C. The results showed liquid fuels have the largest percentage of gasoline (C8-C12) are 92.76; 91.92 and 90.58 percent fraction produced. The performance of catalyst showed that reuseability number were decrease, but the charactersitic of liquid fuel produced were also be agreeable to commercial gasoline standard.

Indonesia with a very large population, is currently working hard to diversify its energy, in order to meet energy needs in the country, especially electricity and fuel energy, preferably environmentally friendly renewable energy, when this plastic waste becomes national problems because they cannot decompose under ordinary conditions unless they are converted into chemical fuel. This study aims to obtain liquid fuel energy, in this case used HDPE plastic waste raw material (in the form of packaged drinking water), this plastic waste is processed using the Catalitic Cracking method with silica Alumina as a catalyst, the process lasts for 4 hours with a temperature of 100 -400oC and 53% of the plastic oil obtained, brownish yellow, with density and viscosity and flash point approaching kerosine compounds to diesel fuel, in the process of catalytic cracking, temperature factors, process length and the catalyst used greatly affect the number of products and product quality from the liquid fuel produced.

In this paper, micro-mesoporous HZSM-5/MCM-41 zeolites were prepared by a two-step hydrothermal method using commercial HZSM-5 with two different silica/alumina ratios (38 and 50) as starting materials. The structures, morphologies and acidity of as-prepared zeolites were analyzed using XRD, FT-IR, SEM, N2-adsorption/desorption and NH3-TPD. The HZSM-5/MCM-41 zeolites combined the acidity of microporous HZSM-5 with the pore advantages of mesoporous MCM-41. Mesopores and microspores of 3.34 and 0.95 nm in diameter were found to be present in HZSM-5/MCM-41 zeolites. When they were used to catalyze the pyrolysis of waste tires, the selectivity of light olefins for HZSM-5/MCM-41 prepared using HZSM-5 with the silica/alumina ratio of 50 as starting materials was 21.42%, higher than 18.43% of HZSM-5/MCM-41synthesized using HZSM-5 with the silica/alumina ratio of 38. In order to further overcome the pore size constraints and mass transfer limitations of HZSM-5/MCM-41 zeolites for catalyzing pyrolysis of waste tires, macroporous ?-Al2O3 were mixed with HZSM-5/MCM-41 and used as catalysts. The selectivity to light olefins for the mixture of ?-Al2O3 and HZSM-5/MCM-41 prepared using HZSM-5 with the silica/alumina ratio of 50 as starting materials was 33.65%, which was obviously enhanced by the introduction of ?-Al2O3.

High Spatial Resolution Imaging

We have used high spatial resolution imaging secondary ion mass spectrometry (SIMS) to differentiate mineralogical phases and to investigate chemical segregations in fluidized catalytic cracking (FCC) catalyst particles. The oil industry relies on heterogeneous catalysis using these catalysts to convert heavy hydrocarbon fractions into high quality gasoline and fuel oil components. Catalyst performance is strongly influenced by catalyst microstructure and composition, with different chemical reactions occurring at specific types of sites within the particle. The zeolitic portions of the particle, where the majority of the oil conversion occurs, can be clearly distinguished from the surrounding silica-alumina matrix in analytical SIMS images.The University of Chicago scanning ion microprobe (SIM) employed in this study has been described previously. For these analyses, the instrument was operated with a 40 keV, 10 pA Ga+ primary ion probe focused to a 30 nm FWHM spot. Elemental SIMS maps were obtained from 10×10 μm2 areas in times not exceeding 524s.

AbstractGlobal plastic waste generation is about 300 million metric tons annually and poses crucial health and environmental problems. Africa is the second most polluted continent in the world, with over 500 shipping containers of waste being imported every month. The US Environmental Protection Agency (EPA) report suggests that about 75% of this plastic waste ends up in landfills. However, landfills management is associated with high environmental costs and loss of energy. In addition, landfill leachates end up in water bodies, are very detrimental to human health, and poison marine ecosystems. Therefore, it is imperative to explore eco-friendly techniques to transform plastic waste into valuable products in a sustainable environment. The trade-offs of using plastic waste for road construction and as a component in cementitious composites are discussed. The challenges and benefits of producing liquid fuels from plastic waste are also addressed. The recycling of plastic waste to liquid end-products was found to be a sustainable way of helping the environment with beneficial economic impact.
