变换型煤用于制造低含量CO水煤气气化的研究

Study on Briquette Gasification to Make Low CO Content Blue Gas

在小型单管气化反应炉内进行了本题的研究。用粉煤和变换剂制成的型煤进行了水煤气气化反应试验。考察了变换剂种类、添加量、气化反应温度、反应时间、蒸汽流量对煤气组成的产气率的影响。结果表明，Ｃａ基变换剂可使煤气中ＣＯ含量降低０．１０左右Ｃａ－Ｎａ复合变换剂还可显著提高煤气产率。并从水煤气两段炉工业气化试验验证了该试验结果。从而简化了制气工艺流程，也降低了煤气成本。

This paper describes a gasification study using briquettes in a small single tube reactor. The gasification test for producing blue gas was conducted with briquettes made by a mixture of fine coal and shift agents. It has been studied that the composition and yield of product gas are affected by several conditions such as:the type and quantity of the shift agent; temperature and time of gasification reaction;steam flow rate etc.The results indicate that the Ca-group shift agent can reduce CO content about 10%;and the Ca-Na compound shift agent can increase gas yield greatly.These results have been verified through the industrial gasification test in a twostage blue gas gasifier.So the process of gasification can be simplified and the gas cost can be reduced.
