As vinyl chloride synthesized from acetylene and hydrogen chloride is further converted into polyvinyl chloride, mercuric chloride must be made use of as a catalyst and activated carbon as a carrier. For the latter high mechanical intensity and strong absorption are required. In the past years such activated carbon has been produced in a few expensive An-shi furnaces where high-grade coal is used. Therefore, it cannot meet the social demands.

As vinyl chloride synthesized from acetylene and hydrogen chloride is further converted into polyvinyl chloride, mercuric chloride must be made use of as a catalyst and activated carbon as a carrier. For the latter high mechanical intensity and strong absorption are required. In the past years such activated carbon has been produced in a few expensive An-shi furnaces where high-grade coal is used. Therefore, it cannot meet the social demands. The present article is to introduce another technological process for making this kind of activated carbon in the serious-heating and multi-tubed furnaces, including its experiment data obtained. Because of the low cost of these furnaces, this technique could be popularized as a new method for producing mercuric carbon nowadays.

用乙炔和氯化氢合成氯乙烯进一步聚合成聚氯乙烯时,需用氯化汞为催化剂,並以活性炭为载体。此种活性炭要求机械强度高,吸附力强。过去我国多是利用优质煤,在造价很高的鞍式炉中制取,几乎是独家生产,远不能满足用户需求。本文介绍串用焖烧炉和多管炉生产此种活性炭的新方法,为生产载汞用炭提供了一条新的途径。
