在５２４Ｋ、２．３１ＭＰａ和１８４５ｈ￣（－１）条件下，考察了合成气（Ｈ＿２／ＣＯ＝２．１）中ＣＯＳ浓度分别为５１．４、１２８．８、１６２．７和２４５．６ｐｐｍ对Ｆｅ－Ｃｕ－Ｋ工业催化剂ＦＴ合成催化性能的影响。实验表明，催化剂预先中毒比在线中毒速率快。大颗粒催化剂的抗硫能力比小颗粒催化剂强。催化剂ＦＴ合成失活速率与ＣＯＳ浓度有关，即高浓度条件下，催化剂的失活速率快。当温度为５２４Ｋ时，催化剂的失活速率最快。Ｈ＿２／ＣＯ利用比和产物中ＣＨ＿４选择性随着催化剂中硫含量的增加显著增加，而产物中ＣＯ＿２／Ｈ＿２Ｏ比和ＣＯ＿２选择性却降低。温度对Ｈ＿２／ＣＯ利用比以及产物中ＣＯ＿２／Ｈ＿２Ｏ比也有影响。
Under the conditions of 524K, 2.31MPa and 1845h ~ (-1), the COS concentrations in synthetic gas (H 2 / CO = 2.1) were 51.4, 128.8, 162.7 and 245.6 ppm Effect of Fe-Cu-K Industrial Catalyst on FT Synthesis Catalytic Performance. Experiments show that the catalyst pre-poisoning than online poisoning rate faster. The ability of large particle catalyst to resist sulfur is stronger than that of small particle catalyst. The deactivation rate of the catalyst FT synthesis is related to the COS concentration, that is, the catalyst deactivation rate is high under high concentration conditions. When the temperature is 524K, the catalyst deactivation rate is the fastest. The H 2 / CO ratio and CH 4 selectivity in the product increased with the increase of sulfur content in the catalyst, but the CO 2 / H 2 O ratio and CO 2 selectivity in the product decreased. The effect of temperature on H 2 / CO utilization ratio and CO 2 / H 2 O ratio in the product is also affected.
