“…The liquid products are distributed in C 5 -C 20 range, that is, basically in the gasoline and diesel ranges. The effect of nonacidic catalysts for the pyrolysis of plastics was studied by Jan et al [6]. On comparison with MgCO 3 when used as a catalyst under 450 ∘ C, it could be observed that the % oil yield (33.60%) is higher with MgCO 3 as compared to the % oil yield (29.60%) obtained with BaCO 3 catalyst.…”

The present work involves the synthesis of a petroleum-based fuel by the catalytic pyrolysis of waste plastics. Catalytic pyrolysis involves the degradation of the polymeric materials by heating them in the absence of oxygen and in the presence of a catalyst. In the present study different oil samples are produced using different catalysts under different reaction conditions from waste plastics. The synthesized oil samples are subjected to a parametric study based on the oil yield, selectivity of the oil, fuel properties, and reaction temperature. Depending on the results from the above study, an optimization of the catalyst and reaction conditions was done. Gas chromatography-mass spectrometry of the selected optimized sample was done to find out its chemical composition. Finally, performance analysis of the selected oil sample was carried out on a compression ignition (CI) engine. Polythene bags are selected as the source of waste plastics. The catalysts used for the study include silica, alumina, Y zeolite, barium carbonate, zeolite, and their combinations. The pyrolysis reaction was carried at polymer to catalyst ratio of 10 : 1. The reaction temperature ranges between 400 ∘ C and 550 ∘ C. The inert atmosphere for the pyrolysis was provided by using nitrogen as a carrier gas.

“…The medium pore SAPOs are attractive for catalytic applications due to the presence of specific acid sites in its structure which can convert the polymer into useful hydrocarbons (Elordi et al, 2009, Singhal et al, 2010. The use of BaCO 3 as a catalyst for the thermal and catalytic degradation of waste HDPE was also reported (Rasul Jan et al, 2010).…”

“…The gases and oils were collected using different bladder and vessels separately, and this pyrolysis reactor was used to degrade the high‐density polyethylene (HDPE) using BaCO 3 and CaCO 3 as catalysts that gave low wax formation and hydrocarbons with minimized boiling point. It indicates that continuous cracking taking place in a long‐chain hydrocarbon generated from thermal degradations and the catalyzed oil fractions properties resembled with standard petroleum products such as gasoline, kerosene, and diesel with temperatures of 100, 150, and 250 °C, respectively . The catalytic fluidized process was carried out with waste consumer plastic bottles form hospitals in a temperature range of 330 to 450 °C with various catalysts, and the zeolite‐based fluid catalytic cracking (FCC)‐R1 catalyst at 390 °C gave more gasoline fractions (54.8 wt.% of C 4 –C 9 and 24.3 wt.% of C 1 –C 4 ) with reasonable conversion efficiency.…”

Summary The utilization of plastics has increased in packing sectors consistently, which lead indirectly to increased volumes of plastic wastes posing an environmental threat. Several utilization and recycling techniques of waste plastics are being practiced commercially around the world. In this article, recent conversion techniques of fuel oil from waste plastics and its utilization on a compression‐ignition engine are discussed. Recent statistics says most of the plastic wastes are generated from packing industries that contains polyethylene, polypropylene. In this connection, conversion techniques of polyethylene and polypropylene practiced frequently by researchers include catalytic processing, thermal degradation, and co‐processing. The effect of various parameters like catalysts, reaction temperature, and reaction time of the aforementioned conversion techniques are discussed in this review. Also, few research works about the utilization of waste plastic oil with a compression‐ignition engine along with engine performance and emissions in various blends of diesel with plastic oil are highlighted here.
