Ｋ－Ｆｅ－ＭｎＯ／Ｓｉｌｉｃａｌｉｔｅ－２催化剂经１００ｍｌ模试反应装置评价表明，其ＣＯ加氢制低碳烯烃反应性能可达到小试结果，且反应温度可降低５０～６０℃，催化剂具有良好的操作稳定性；提高反应温度（尤其是反应器入口温度）将导致低碳烯烃选择性大幅度下降，增加反应气空速有利于提高低碳烯烃选择性，而增大反应压力则不利于提高其选择性。 The evaluation of K-Fe-MnO / Silicalite-2 catalyst by 100ml reaction device shows that the reaction performance of CO-hydrogenation of light olefins can reach the small test results, and the reaction temperature can be reduced by 50 ~ 60 ℃, and the catalyst has good operation Stability; increasing the reaction temperature (especially the reactor inlet temperature) will lead to a substantial decrease in the selectivity of light olefins, increasing the space velocity of the reaction gas is beneficial to improve the selectivity of light olefins, while increasing the reaction pressure is not conducive to improving its choice Sex.
