THC and CO Emissions from Diesel Engines Using Biodiesel Produced from Residual Frying Oil by Non-Thermal Plasma Technology

Research aimed at finding alternative fuels to replace petroleum diesel (petrodiesel) used in controlled combustion engines (CCEs) has identified biodiesel as one of the main candidates, due its sustainability and potential for use energy matrices. In this study, gas emissions from a CCE were investigated, with focus on total hydrocarbons (THC) carbon monoxide (CO). Biodiesel (B100) samples derived transesterification frying oil, produced applying conventional chemical catalysis (CC) or non-thermal plasma (NTP) technology, tested fuels. Three engine rotation speeds investigated (900, 1500, 2500 rpm) obtained residual oil compared road (S-500) without added, acquired station. Blends also prepared S-500 B100 NTP 15 30 min, mixes containing 2, 12, 20, 50% biodiesel. These blends showed reductions THC CO 62% 80%, respectively, 100% S-500. Thus, offers low THC, highlighting using technology.
