The procedure for biodiesel production directly from wet microalgae ( Chlorella vulgaris ) assisted by radio frequency (RF) heating was optimized in this study using response surface methodology (RSM). A three-variable, five-level central composite design (CCD) was employed to evaluate the...

Efficient biodiesel production from beef tallow was achieved with radio frequency (RF) heating. A conversion rate of 96.3 ± 0.5% was obtained with a NaOH concentration of 0.6% (based on tallow), an RF heating for 5 min, and a methanol/tallow molar ratio of 9:1. Response surface methodology...
