一、绪言1956年高教部转来化工设计局有关测定硫化铵及多硫化铵溶液性质的题目,希望我院进行研究。经几次联系后,基本上明确本题是有关在燃料气中用活性炭脱硫,及再用硫化铵再生活性炭的题目。其生产过程原理简述如下: I. INTRODUCTION In 1956, the Ministry of Higher Education turned to the Bureau of Chemical Design Bureau for the topic of measuring the properties of ammonium sulphide and ammonium sulphide solutions and hoped that our hospital would conduct research. After several contacts, basically clear this question is about the use of activated carbon in fuel gas desulfurization, and reuse of ammonium sulphide regeneration of activated carbon topics. The principle of its production process is summarized as follows:
