摘　　要：设计并模拟了以Shell和GSP技术为气头的IGCC系统,包括对合成气中的CO进行95%深度变换和不进行变换的不同方案.结果表明,Shell气化为气头的带深度变换和无变换的IGCC系统分别具有34.8%和41.8%的系统热效率.深度变换的优点在于能大规模降低CO2排放,碳的捕获量占系统总碳量的92.5%(Shell,深度变换),而无变换的IGCC方案,这一比例为0.2%.IGCC systems based on Shell and GSP gasification are designed and simulated, including a deep shift with 95 % of CO conversion and no shift. The results show that the IGCC systems with the deep shift and without the deep shift based on the Shell gasification has the thermal efficiency of 41.8% and 34.8% respectively. The advantage of the system with the deep shift is that can greatly decrease CO2 vent. The ratio of carbon capture to total carbon is 92. 5% However, to the IGCCs with no shift, this ratio is 0.2%.
