In this research, the optimum conditions were using commercial SrO, 40 to 180 seconds reaction time,
around 80o
C reaction temperature, 6 methanol to oil ratio, and 1000W microwave power output. 99% and
93 % biodiesel conversion efficiency for cooking oil and waste cooking oil were reached within in these
conditions. The determined specifications of obtained biodiesel according to ASTM D6751 and EN14214
standards were in accordance with the required limits. As a conclusion, the present study indicates that
derived fuel promises being an alternative for diesel, and could be used in engines without a major
modification due to its qualifications.
