摘要
羰基硫水解催化剂用于5万t/a合成甲醇的原料气精脱硫,至今已运行了10个月。结果表明,含1-100mg/m ̄3羰基硫的原料气,在温度为100—210℃、空速为3000—6000h ̄(-1)、压力为2.7MPa下,通过固定床反应器;羰基硫在催化剂上的水解转化率可达90%以上。在整个运行期间,催化剂活性保持稳定、具有强的抗硫酸盐化中毒的性能。
COS hydrolysis catalyst for fine desulfurization of syngas is used in a 50000 tpy synmethanol unit.Results from 10 months of operation indicate that COS hydrolysis conversion over the catalyst is above 90%,when syngas with 1─100mg/m ̄3 COS passes through the catalyst bed at 100─ 210℃,3000─6000h ̄(-1) and 2.7MPa。The COS conversion is steady throughout the operation,and the hydrolysis catalyst is strongly resistant against sulphated poisoning.
