ġġġġġIn the transitional process, acid or base catalysts are common technology to produce bio-diesel from
waste cooking oil; however, the catalysts only can be use one time. Highly reaction time is requirement
for the transitional technology. For improvement these concern issues, this study applied a novel
technology to create bio-diesel product from cooking oil and waste cooking oil by microwave irritation.
The microwave irradiation can provide strong power and reach reaction temperature in a short time. The
SrO catalyst is a heterogeneous catalyst which is not dissolution into any liquid solution therefore, it can
be recycling and reusing again.
