用脉冲色谱法考察了不同助剂及载体对镍催化剂甲烷化活性和抗硫性的影响,探索了提高镍催化剂抗硫性的途径。并用连续流动法测定了自制的抗硫性能较好的镍催化剂用于煤气甲烷化的活性及寿命。
The effects of different additives and supports on the methanation activity and sulfur resistance of nickel catalysts were investigated by pulse chromatography. The ways to improve the sulfur resistance of nickel catalysts were explored. The activity and life span of gas methane methanation were determined by the continuous flow method.
