A Competent, Humble Cost Catalyst from Biowaste: High Performance and Combustion Characteristics of Alternative Diesel Fuel

Abstract

This current work displays experimental results obtained from assessing the methyl esters from the local waste cooking oil as an alternative fuel for diesel engines using a heterogeneous catalyst based on agricultural waste. The performance of the diesel engines and their exhaust emissions have been experimentally investigated using the produced biodiesel from waste cooking oil as a blend with fossil fuel (B10, B15, and B20) compared to the diesel. The reusability of the catalyst confirmed a high conversion efficiency after 8 cycles of the production. The highest conversion efficiency of the converting waste cooking oil extended to 90.38% with 92.5% maximum mass yield and methyl ester content of 97.7% wt. at the optimized conditions. According to the results, the effective blend for thermal efficiency and specific fuel usage is B15. Also, all emission concentrations decrease with increasing the engine load, especially for B15 fuels compared to diesel oil.

The performance of a developed diesel vehicle to run on WCO biodiesel at variable speeds and loads

“…The brake thermal efficiency (BTE) of engines utilizing methyl-diesel mixtures is reduced as the fraction of biodiesel increases, owing to the lower calorific value of methyl esters (Mohamed et al 2022;Ramesh 2016;Rao et al 2007;Suresh et al 2012). Biodiesel is less thermally efficient than pure diesel because of its greater viscosity (El-Baz et al 2017;Gad and Abu Ha-shish 2018;Suresh et al 2012).…”
