Abstract
Biodiesel is a sustainable and renewable source of
fuel. It has been considered as a comparable substitute
to petro-diesel, which is a fast depleting resource.
Many studies have been undertaken on biodiesel
production from various feedstock as a result
of its importance. The differences between the physico-
chemical properties of biodiesel and petrodiesel
were considered with the aim of justifying the
applicability of biodiesel in compression ignition
engines (CIE). It was established that biodiesel has
relatively close BTE (brake thermal efficiency) and
BSFC (brake specific fuel consumption) values with
petro-diesel, hence, is suitable for CIE operation
without any modification. The exhaust from CIE
using biodiesel was lower compared to petro-diesel
and this confirms the environmental friendliness of
biodiesel. The catalyst being an important substance
in the transesterification reaction of vegetable oil/
animal fat to produce biodiesel was comprehensively
discussed, and heterogeneous catalysts were
established to be preferred due to several advantages
over homogenous catalysts. This paper reviews biodiesel
production, prospects, benefits and challenges
as a replacement for petrol diesel.
