“…83 Secondly, pyro-oil and pyro gas can serve as alternative fuels, potentially conserving fossil fuel resources for the future. 84 The overall efficiency of the system can be improved by employing fly ash as a catalyst, while also contributing to the mitigation of hazardous waste in the environment. This approach offers a superior waste management option compared to gasification and non-catalytic processes because gasification temperature is higher than pyrolysis temperature.…”

“…In earlier studies, coal-fly ash was utilized in pyrolysis after undergoing treatment with an acid or alkali. 33 However, in the current study, the fuel oil fly ash was simply rinsed with deionized water, dried in an oven at 110 °C to eliminate moisture, and then employed in catalytic pyrolysis. The experiments were conducted using a large-scale batch reactor to yield significant outcomes, thereby facilitating the potential commercialization of plastic catalytic pyrolysis.…”

“…Furthermore, researchers have discovered that y ash can be used as a catalyst for the pyrolysis of LDPE and polypropylene. 27,28 Mondal et al 29 used coal y ash in pyrolysis of waste plastic and used a 25% ratio of coal y ash and found 96% conversion. Similarly, Misran et al 30 used coal y ash as a catalyst in pyrolysis of plastics as well.…”

“…This unique blend of minerals unlocks its potential as a low-cost catalyst in various processes, including: waste reduction, environmental mitigation and transportation infrastructure. Recent research explores utilizing fly ash in the pyrolysis of waste plastic, transforming it into liquid hydrocarbon fuels, such as WPO, effectively tackling plastic waste while generating a valuable resource [11,12]. While other catalysts, like zeolites, demonstrate high conversion rates, their cost can be prohibitive.…”

Fossil fuels are quickly draining on a daily basis, causing fuel product prices to increase throughout the world. There is a crucial need to develop new alternate fuels from various sources that meet our daily requirements, like industries, mining, building construction, transportation, electric power generation from rural areas, etc. In the present study, mono-use low density polyethylene (LDPE) was successfully transformed into a liquid form of hydrocarbon fuel with fly ash-supported catalytic pyrolysis. The ratio of 0.1 with reference to catalyst-to-feedstock was fixed for the preparation of waste plastic oil (WPO) using batch-type pyrolysis reactors. About 180°C was the temperature at which the extracted crude oil was segregated. The diesel fuel's properties and those of the WPO fuel were compared and evaluated. Experiments were carried out using diesel-WPO mixed fuel (10%, 20%, 30%, and 40%) in a multi-cylinder, water-cooled Common Rail Direct Injection (CRDI) diesel engine. Additionally, the impact of the compression and mixing ratios on performance, emission characteristics, and combustion was studied. We observed significant improvement in the results of BTE and BSFC for the tested fuel blend, D80WPO20, compared to other blends. Additionally, it has been demonstrated that the emissions of CO, HC, and NOx rise with an increasing fuel mixing ratio. Based on the analysis carried out on performance and emissions, it was determined that D80WPO20 was the best combination.
