摘　　要：以污泥添加量为２％（干基）白泥添加量为０３％（干基）所制得的污泥型煤为研究对象，以白泥添加量为５５％的白泥型煤作为参照，考察了污泥型煤的气化特性和二次污染．研究结果表明，在１１００℃以上高温下，污泥型煤的气化速率比白泥型煤高５０％以上；污泥型煤的灰渣软化温度达１４４０℃，能满足合成氨气化要求；污泥型煤无二次污染，其气化成分符合合成氨原料气的要求．Sewage sludge briquette made of 2%(dry basis) sewage sludge,0 3% white earth, and coal powder was studied under conditions of briquette similar to modeling and gasificaition for briquette on ammonia synthesis.Briguette with white earth was taken as a reference.The results showed that rate of gasification of sewage sludge briquette was 50% higher than that of briquette of white earth at 1100℃.Ash melting point of sewage sludge briquette reached 1440℃ which satisfied the requirement of gasification of ammonia synthesis.Results showed that no pollution took place in these processes,and the gas generated can meet the demand of ammonia synthesis.
