Biodiesel dari Limbah Pabrik Gula dan Minyak Jarak Pagar (Jatropha curcas) dengan Katalisator Zeolit Alam Klinoptilolite
Abstract: The fuel price
increase with the increase of the number of transportation due to the
increasing numbers of the population. Indonesia with more than 200 million
people in need of transportation fuels in the form of gasoline and diesel in
large quantities. Currently the main source of transportation fuels derived
from petroleum. Premium production in Indonesia is about 62 million barrels and
production of about 87 million barrels of diesel fuel. The product does not
include the use for other needs, such as lubricating oil, kerosene, avgas, as
well as other materials. This is particularly worrying given the oil reserves
are dwindling. One of the alternative energy for transportation fuels is
biodiesel as a substitute for diesel fuel.The castor oil has potential to be
used as biodiesel. Fusel oil is a sugar mill waste containing alcohol. The
reaction between castor oil and fusel oil with natural zeolite catalyst
klinoptilolite be referred to as alcoholysis reactions that produce esters. Castor
oil and fusel oil mixed with zeolite powder klinoptilolite that previously had
been heated in a separate place until it reached its boiling temperature. Three
neck flask fitted with a thermometer, hoses trailer makers, heater, and the
agitator on 100 rpm with 100 oC of temperature. Snapshot taken at intervals of
30 minutes each. Conversion reaction calculated by analyzing the levels of
glycerol bottom layer by means asetin. Alcoholysis fusel oil and castor oil
with natural zeolite catalyst klinoptilolite produce esters that are
approaching the properties of diesel oil with a calorific value of 19 119
Btu/lb. Optimum conversion of 57 % was obtained in alcohol - oil ratio of 9.29
mgek/mgek and the addition of a catalyst as much as 2.56% of the weight of oil.
