摘要

Ethylene glycol monobutyl ether palm oil monoester (EGMEPM) was synthesized through transesterification with palm oil and Ethylene glycol monobutyl ether (EGME). Through L_9(3~4) orthogonal experiments, optimum transesterification conditions were gained as: n(EGME):n(palm oil) = 10:1, w(metal sodium) = 1.2% total amount of alcohol at 70℃ for 120 min. EGMEPM yielded 85.7%. The new biofuel had a high cetane number (77), good solubility, and a large flash point. Engine combustion experiment testified that burning the novel bioenergy has little influence on engine operation. Compared with 0# diesel fuel, the pressure lifting ratio reduced 2.9%-23.9% for B25 blends and 12.8%-38.9% for the novel bioenergy (B100), and the maximal instantaneous heat release rate lowered by 11.6%-33.3% for B25 and by 26.8%-42.7% for BI00, respectively. When the diesel engine burnt B100 under partial loads at 1400 rpm, smoke, CO, HC, and NOx emissions were reduced.
