Abstract :
Recently, environmental, social and
sustainability issues associated with use of fossil-based
fuels are generating much concern and interest for the
development of renewable energy. Catalyst design and
development is critical and occupying central position for
successful conversion of renewable feedstock to renewable
fuels. In this work, optimization of reaction parameters
that influences catalytic performance particularly
biodiesel yield and catalyst reusability were tailored to
enhance catalytic activities of basic anionic (AmerlystA26) and acidic cationic (Amberlyst-36) ion-exchange
resins in transesterification of vegetable oil with methanol
to biodiesel using both conventional and autoclave
biodiesel synthesis. Basic anionic Amberlyst-A26 catalyst
has demonstrated great potential for biodiesel synthesis
with Sunflower oil than the acidic cationic Amberlsyt-36
resin using the conventional-round bottom flask method.
Biodiesel yield >90% was obtained at temperature as low
as 40 oC and a yield >75% within 1 hour at 50 oC. The
catalyst showed higher degree of reusability by losing only
19% of its original activity after thirteen cycles.
Conversely, autoclave biodiesel synthesis carried out using
both catalysts revealed that the acidic Amberlyst-36 is
more active under severe reaction conditions of autoclave.
Hence, polymeric resins are viable active solid catalyst for
biodiesel synthesis capable resisting leaching of active sites
and loss of activity during biodiesel synthesis provided the
right reaction conditions are explored
