摘要：The experiments were designed to remove HCl, NH3, organic sulfur and tar component in high temperature coal-derived 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 COS and CS2 were used as organic sulfur model compounds. It is found that the Ni-3 (4.0 wt% NiO, 14.3wt% MoO3 and Al2O3) catalyst can play a multifunctional role. It is an effective catalyst for NH3 and tar component removal; Ni-3 catalyst is also effective for removal of COS and CS2 by converting them to H2S. Self-prepared ECl sorbent displays the highest adsorption capacity for HCl vapor. The simultaneous removal of HCl, NH3, organic sulfur, and tar component has been studied at a reaction temperature range from 300 to 550°C. It indicates that the simultaneous removal of organic sulfur, tar component, NH3, and HCl is feasible by using combined ECl sorbent and Ni-3 catalyst in a fixed-bed reactor. In addition, the effect of sulfur on Ni-3 catalyst and Ni-3 catalyst life were also studied.
