日本的煤炭快速热解技术

为了开发独具特色的煤炭快速热解技术 ,日本先后建立了原料煤处理量分别为 7t/d和 10 0t/d的工艺开发和中间试验装置。大量的试验研究结果表明 :1t高挥发分原料煤经过快速热解 ,大致可以得到低热值为 17 87MJ/m3的煤气 10 0 0m3、半焦 2 50kg、焦油 70kg、苯类 (主要是苯、甲苯及二甲苯 ) 35kg ,同时还可副产水蒸气约 30 0kg。目前 ,中试研究仍在进行中 A process research unit of entrained bed coal flash prolysis process which has a coal feeding capacity of 7 t/d, and a pilot plant which has a coal input of 100 t/d have been built in Japan. The result is shown that, about 1000 m 3 of coal gas with a heating value of 17 87 MJ/m 3, 250 kg of char, 70 kg tar and 35 kg of BTX can be obtained from 1 t of raw coal by this pyrolysis process. Besides, nearly 300 kg of steam is also produced as by-product. At present, the pilot plant study of thi process is underway. This paper presents a brief introduction to some information on the development of the process and result obtained
