Abstract: In the current study, syngas is produced by the thermal breakdown of glycerol derived from biodiesel manufacturing procedures. High temperatures cause the organic material to decompose, releasing hydrogen, carbon monoxide, carbon dioxide, methane, and light hydrocarbons, sometimes known as syngas or producer gas. In this study, a high-temperature process involving the thermal breakdown of glycerol is used to produce syngas. The Aqueous Phase Reforming (APR) method uses various catalyst support materials, including alumina, Lanthanum, and ceria, along with nickel as a catalyst to enhance the production rate of syngas. Syngas is created using several ratios of glycerol and water combinations, such as 1:1, 1:2, 1:3, and 1:4, on a mass basis, at reaction temperatures of 240 °C, 260 °C, and 280 °C. The yield parameters of the APR process using alumina as a support material and a nickel catalyst. The investigation demonstrated the viability of using syngas in CI engines, which did not affect engine performance but resulted in 18 % reduction in NOx owing to using a homogenous charge and smoke is decreased by 12 %. The combustion study showed a better heat release rate and cylinder peak pressure of 64 kJ/°CA and 64 bar at peak load, respectively.
