抄録
To co-produce hydrogen and benzene from biogas、 the demonstration plant was placed. They were co-produced by dehydro-aromatization reaction of methane and steam reforming of un-reacted methane. The material and energy balance and the CO2 emission of the experimental facility were clarified. To evaluate the experimental facility、 exergy analysis was carried out. 21% of the input exergy was converted to hydrogen and benzene、 and the remaining 79% was consumed in the chemical and physical operation or discharged as waste heat、 exhaust gas and refuse. The dehydro-aromatization reformer sub-system showed the highest exergy loss. Increasing heat insulation or heat exchange in this sub-system could significantly reduce the overall loss. Assuming electricity and heat were supplied by using biogas、 reforming 1m3 of biogas required 3.88m3 of biogas and the CO2 emission was not considered. In the same case co-producing 1m3 of hydrogen and 0.064L of benzene required 5.79m3 of biogas.
