摘要
以焦粉为原料,煤焦油、环氧树脂为粘结剂,采取先浸渍再碳化的方法制备空分制氮用的碳分子筛(Carbon molecular sieve,CMS)。实验结果表明:当用煤焦油与树脂为粘结剂,粘结剂的含量为20%,碳化温度为700℃,恒温时间为30 min,浸渍时间为30 min时制备的碳分子筛的空分性能最佳,可使空气中的氮气含量达到90%。
The carbon molecular sieve was prepared with coke powder;epoxy resin and coal tar match the compound binder.Taking charring before dipping as method of their pretreatment to prepare the Carbon molecular sieve,the results showed that:When using coal tar and resin as binder,the binder content is 20%,the carbonation temperature is 700 ℃,thermostats time is for 30 min,dipping time is for 30 min,carbon molecular sieve for the air separation is the best,the nitrogen content in the air can reach to 90 percent.
