초록

A novel microwave-induced pyrolysis of polystyrene in motor oil was performed using a quartz tube reactor with silicon carbide as the microwave absorbent. Different pyrolysis conditions were investigated, such as time range from 30 minutes to 1 hour and power range from 180 to 250 watt. The distillate components were analyzed with GC-MS, and styrene, 1-methyl styrene, toluene, ethyl benzene were the four main products. Among these, styrene took over 70 percentages. Temperature of the complete pyrolysis using microwave was much lower than that of conventional thermal pyrolysis method.
