Summary: | Catalyst is a substance that enables chemical reaction in faster rate. In biodiesel
production, catalyst plays as an important role as it can increase the rate of the
reaction. The type of catalyst that usually can be found are homogeneous and
heterogeneous catalyst. However, homogenous catalyst is difficult to separate with
the product (biodiesel) at the end of the reaction compared to heterogeneous
catalyst. This will result in production of high waste water and creates issue in
regeneration of the catalyst. In order to overcome the issue, many researchers have
studied about heterogeneous catalyst and the use this type of catalyst in production
of biodiesel. The heterogeneous catalyst can be developed from natural resources
such as animal bone, waste and natural rock which is a type of alkali earth oxides. A
way to improve the catalytic activity of the catalyst used is increase its surface area
by preparing it in nano-sized of catalyst. Nano-catalyst has a high catalytic efficiency,
large surface area, high resistance to saponification and good rigidity. However, the
thermal condition during decomposition of catalyst could influence the activity of the
catalyst during the reaction. Therefore, the reaction rate and the catalytic activity of
the catalyst during transesterification reaction can be affected by the type of catalyst
and the thermal condition involved during the preparation of the catalyst. |
