Abstract
The draining of fossil fuels and their toxic influence
on the environment has prompted the need for
alternative fuels known as biofuels. Of the various
types of biofuel, biodiesel has attracted wide interest
in the world today since it promotes carbon neutral
ity. The transesterification and interesterification
process remains the most widely used process route
for biodiesel production. In this review, the perfor
mance efficiency of solid base, solid acid, and bi
functional solid acid-base catalysts for biodiesel pro
duction from waste cooking oil is considered. In
particular, the benefit of exploring the biomass
derived acid-base heterogeneous bifunctional cata
lysts, current status, and future prospects for biodie
sel production from waste cooking oil are eluci
dated.
