Optimization and kinetic studies on biodiesel conversion from Chlorella vulgaris microalgae using pyrrolidinium-based ionic liquids as a catalyst

This study describes the potential conversion of dried microalgae. Chlorella vulgaris (C. vul-garis) into fatty acid methyl ester (FAME) using the direct transesterification (DT) method and using ionic liquids (ILs) as a catalyst. In this work, the performance of monocationic IL, namely 1-butyl-1-me...
