Abstract
Domestic large methanol plants mainly use foreign methanol synthesis process packages and catalysts,which is not conducive to the long-term and stable development of modern coal chemical technology in China.China Shenhua Coal to Liquid Chemical Co.,Ltd.realized the application of domestic methanol synthesis catalyst in a methanol plant with productivity of 180×104 t/a for the first time.The physicochemical parameters,heating reduction process and operation of a foreign methanol synthesis catalyst(M catalyst)and a domestic methanol synthesis catalyst(C catalyst)were compared and analyzed.The results show that compared with M catalyst,C catalyst has the advantages of high activity(especially low temperature activity),strong stability,high per pass conversion rates of gas,and less by-products and wax.In addition,C catalyst has a better energy saving effect than M catalyst,and under set up conditions(electricity price is 0.3 CNY/(kW·h),water price is 0.15 CNY/t and steam price is 100 CNY/t),using C catalyst can save about 667.8×104 CNY/a.At present,C catalyst has been running stably in the plant for more than one year,and the production load of the plant is close to 110%.关键词
