我厂自采用甲烷化工艺以来 ,由于氧化铁、氧化锌脱除有机硫效果不佳 ,致使甲烷化催化剂使用寿命只有 1年左右。后采用ＳＨ -Ｔ51 4-Ｂ型脱硫剂 ,取得了满意的效果。1 使用效果ＳＨ -Ｔ51 4-Ｂ型脱硫剂于 1 999年 2月投入使用至今 ,甲烷化催化剂未发现中毒现象 ,由气相色谱仪 -
Since our factory using methanation process, due to iron oxide, zinc oxide removal of organic sulfur ineffective, resulting in methanation catalyst life of only about 1 year. After using SH -T51 4-B desulfurizer, and achieved satisfactory results. 1 Effect SH -T51 4-B type desulfurizer put into use in February 1999 so far, no evidence of poisoning methanation catalyst by gas chromatography -
