摘要
上海赛科通过甲烷化的方法除去氢气中少量的CO。甲烷化最初使用高温催化剂,2014年4月更换为低温催化剂。本文对两种催化剂应用情况进行了介绍和比较。将低温催化剂入口温度从以往的287℃降低至170℃,富氢体系中的CO仍可完全反应,这不仅大大地提高了催化剂的操作弹性和催化剂的稳定性,而且可停用超高压蒸汽(1.5t/h),这也消除了超高压蒸汽泄漏对环境造成危害的风险。
In Shanghai SECCO Petrochemical Company, methanation reaction is used to remove CO from hydrogen. A high temperature methanation catalyst was used initially, and it was replaced by a low temperature one in April 2014. In this paper, the two catalysts were introduced and compared. Reducing the entrance temperature of low temperature catalyst from previous 287℃ to 170℃, CO could still be removed completely from hydrogen, which could greatly improve the operation flexibility and catalyst stability and stop the use of super high temperature steam (SS, 1.5t/h), eliminating the SS leakage risk.
