引言由天然气制备的吸热式气体的基本成份是:20％CO,40％H_2和40％N_2。英国氧气公司(BOC)用氮/甲醇合成的吸热式气氛的Endomix系统在资料[1.3]中已有了很好的说明。本质上,这种工艺就是在炉子的加热室中,以氮气作载气裂解甲醇。在温度高于690℃时,其反应如下: CH_3OH→CO+2H_2 其产品气是一种接近于常规吸热式气体成份的炉气氛。用50％氮气与50％甲醇混合时,Endomix将产生一种含有15％CO和35％H_2、50％N_2的气氛。 BOC的氮/甲醇渗碳工艺是在0.25米~3(9英尺~2)的Efco的密封淬火炉上开发出来的。一开始生产应用就用这种设备当然是一种进步。这种系统的技术和经济的可行性
Introduction The basic components of an endothermic gas made from natural gas are: 20% CO, 40% H 2 and 40% N 2. The Endomix system of BOC’s endothermic atmosphere with nitrogen / methanol synthesis is well documented in [1.3]. Essentially, this process involves cracking the methanol with nitrogen as the carrier gas in the furnace’s heating chamber. At temperatures above 690 ° C the reaction is as follows: CH 3 OH → CO + 2H 2 The product gas is a furnace atmosphere close to the conventional endothermic gas composition. With 50% nitrogen and 50% methanol, Endomix will produce an atmosphere containing 15% CO and 35% H 2, 50% N 2. BOC’s nitrogen / methanol carburizing process was developed on a sealed quench furnace from Efco at 0.25 to 3 (9 feet to 2). Of course, this kind of equipment is a kind of improvement when it comes to manufacturing applications. The technical and economic feasibility of such a system
