PIROLISIS LAMBAT CAMPURAN BATUBARA DAN PLASTIK DENGAN KATALIS ZEOLIT ALAM
Abstract: This research aims
to find out the characteristic of slow pyrolysis of coal and plastic mixtures
involving natural zeolite as catalyst. Coal was screened in the mesh size of -6
+8 and plastic collected from waste grocery bags were cut in small sizes. Coal
and plastic were mixed together in the percentages of 0%, 10%, 20% and 30% of
plastic. Coal and plastic mixtures were feeded in the fixedbed pyrolyzer with
natural zeolite addition then heated until desired temperature (400oC, 450oC
and 500oC) in absence oxygen. The pyrolysis vapor produced from heating was
condensed by separated water cooling. The condensation liquid formed was
collected and analyzed using GCMS to determain the composition of liquid
fraction. This reseach results that the higher temperature pyrolyzer the higher
conversion of coal and plastic mixtures is by reducing char product. In
addition, by the plastic added in the coal pyrolysis enriches alkane compounds
and reduces percentages of PAH compounds. The natural zeolit addition affects
in the increase of percentage of alcohol compounds with the alkene compounds
reduction
