在固定床反应器中对高温煤气中NH3、有机硫化物、HCl及焦油蒸气4种污染物进行了单独和同时脱除的研究，其中选择CS2和1-甲基萘分别作为高温煤气中有机硫化物和焦油蒸气的模型化合物。研究得出，高温煤气中氨催化分解和1-甲基萘催化裂解的最佳催化剂同为Ni-3催化剂，CS2转化的最佳催化剂为硫化态的Ni-3催化剂，最好的脱氯剂为ECl。在NH3、CS2、HCl及1-甲基萘4种污染物同时存在时，将上述脱除剂组合在一起进行同时脱除实验表明：ECl脱氯剂对HCl的转化率和Ni-3催化剂对1-甲基萘的转化率均为100%，氧化态的Ni-3催化剂对NH3的转化率和硫化态的Ni-3催化剂对CS2的转化率则随温度的升高而增加，在300～550°C之间，氨的最大转化率为79%，CS2的最大转化率为88%。

The experiments were designed to remove HCl, NH3, organic sulphur and coal tar component from high temperature coal gas, first separately and individually and then in combination and simultaneously by using a fixed-bed reactor. 1-methylnaphthalene was used as a tar model compound, and CS2 as organic sulphur model compound. The tests show that Ni-3 catalyst is an effective catalyst for NH3 and 1-methylnaphthalene decomposition, Ni-3 catalyst sulphurized is also effective for CS2 conversion, and the self-prepared ECl sorbent displays the highest adsorption capacity for HCl vapor. The simultaneous removal of HCl, NH3, organic sulphur and tar component was studied at the reaction temperature range from 300°C to 550°C. The maximum removal efficiencies are 100%, 100%, 79%, 88% for HCl, 1-methylnaphthalene, NH3, and CS2 respectively.
