Utilization of Plastics Waste Oil as Partial Substitute for Kerosene in Pressurized Cookstoves
Harwin Saptoadi and Nosal N. Pratama
Abstract—The aims of the research are to recycle plastic
wastes into combustible oil and utilize it in cookstoves. One of
simple recycling methods is pyrolysis. Substantial volume of
pyrolytic oil can be obtained along with ignitable gas and
residual char. The composition and quality of these three
products can be improved with an additional catalytic
reforming process. Specifically, this research utilizes indigenous
natural zeolite as catalyst, while the primary raw material is
Polyethylene. Variations in the raw materials are conducted by
adding smaller quantity of other plastic materials. The
maximum temperature in the fixed bed pyrolyzer and the
reformer are 500oC and 450oC, respectively. Nitrogen with 0.8
l/min flow rate is applied as the carrying medium. The results
show that pyrolytic oil obtained from Polyethylene has good
calorific values but unfortunately low yield, thus its recovered
energy is modest. Unintended mixing with other kinds of
plastics will coincidentally help improving the attained thermal
energy. Mass conversion rate of plastics-to-oil varies between
41% and 45%. The oil is then exploited as partial substitute for
kerosene used in cooking stoves. The experiments are carried
out by blending 25 vol-% of pyrolytic oil with 75 vol-% of
kerosene. The results show that firepower varies between 1,609
W and 1,651 W, while the boiling time is almost constant at 23
min. The thermal efficiency fluctuates, corresponding to the
heat, from 47.5 % to 51.1 %, which do not differ significantly
from 53.08 % when 100 % kerosene is used. It is expected that
consumption of kerosene can be considerably reduced by
partial substitution.
