摘要
利用ASPEN PLUS软件建立了生物质氧气气化制备合成气模型,并对各种影响因素进行了深入分析,结果表明,随着O2当量比的增加,合成气的体积分数与产率均先增大后减小,且在当量比为0.16时,合成气的体积分数和产率均达到最大值,分别为97.63%和1.61,m3/kg,此?(H2)/?(CO)也有最大值0.98;高温和低压对制备合成气有利,在加压条件下,合成气体积分数和产率达到平衡组成时的温度提高;水蒸气与生物质之比由0增加到1.5时,?(H2)/?(CO)的值由0.98快速上升至3.06,而?(O2)/?(CO2)的值由1∶0变化到1∶5时,?(H2)/?(CO)的值由0.98快速下降至0.50.
A model of oxygen gasification of biomass for syngas gas production was built using ASPEN PLUS, and the effects of various factors on gasification characteristics were analyzed. The results showed that, as the oxygen biomass equivalence ratio increases, both the synthesis gas concentration and the yield increase first and then decrease and they both reach the maximum values of 97.63% and 1.61 m3/kg respectively at the equivalence ratio of 0.16, and the ratio of hydrogen to carbon monoxide also reaches the maximum value of 0.98. High temperature and low pressure are beneficial for syngas production, and under pressurized conditions, the temperature, at which a balanced concentration and yield of syngas can be achieved, increases. As the mass ratio of steam to biomass in- creases from 0 to 1.5, the ratio of hydrogen to carbon monoxide rapidly increases from 0.98 to 3.06, while the volume ratio of oxygen to carbon dioxide changes from 1 : 0 to 1 : 5, and the ratio of hydrogen to carbon monoxide decreases from 0.98 to 0.50 rapidly.
