摘要：基于ASPEN PLUS模拟平台,对热解后半焦气化与生物质原料直接气化分别进行了模拟计算,得出如下结论:热解方法作为生物质气流床气化工艺的前处理手段是可行的。热解终温为300℃时对气流床气化是最合适的;O/C摩尔比在0.9～1.1之间比较合适;气化温度和碳转化率随着O/C摩尔比的增加而升高;对于300℃半焦进行气化,空气温度预热到550℃比较合适,气化温度可达到1056℃,煤气热值可达到5958kJ/Nm^3,碳转化率也可达到99.59%。
Based on ASPEN PLUS, biomass direct entrained flow gasification was compared with entrained flow gasification after biomass was pyrolyzed. The conclusions are as follows： the pyrolysis method is suitable for biomass entrained flow gasification by way of pre-treatment method. The most appropriate temperature of pyrolysis is 300℃ ; the appropriate molar ratio of oxygen to carbon is ranging between 0. 9 - 1.1 ; gasification temperature and the rate of carbon conversion will increase with raising molar ratio of oxygen to carbon ; for the semi-char at the temperature of 300℃, the appropriate preheated air temperature in the entrained flow gasification is 550℃. And the gasification temperature is 1056℃, its caloric value is 5958kJ/Nm^3 , the rate of carbon conversion is 99.59%.
