Abstract
Biomass samples were converted to charcoal and to liquid and gaseous products by pyrolysis process at different temperatures. Under pyrolysis conditions, plastic wastes can be decomposed into three fractions: gas, liquid, and solid residue. The liquid products are usually composed of higher boiling point hydrocarbons. In order to obtain useful gasoline-range hydrocarbons from the pyrolytic oil, fractional distillation is preferred for product separation. More valuable chemical raw materials including benzene, toluene, and other condensed aromatic hydrocarbons may be obtained by refining the pyrolytic oil. The vegetable oils and their soaps obtained from the vegetable oils can be pyrolyzed into hydrocarbon rich products. The yield of conversion of the sunflower oil reached the maximum 78.3% at 660 K over ZnCl2 catalyst. The maximum gasoline yield of 48 wt% from palm oil was obtained with composite micromesoporous zeolite.
