Abstract
Waste cooking oil (WCO) was converted into biodiesel with methanol over a composites catalyst consisting in SBA-15 with sulfonic acid groups (SBA-15-SO3H) immobilized in poly (vinyl alcohol) (PVA), at 60ºC. It was observed that the catalytic activity increased with the amount of SBA-15-SO3H dispersed in PVA.
The catalytic stability of [SBA-15-SO3H]3/PVA. composite was studied. A good stability was observed.
