Abstract:
ln recent years,domestic coal-to-methanol industry faces,apart from high sulfurization cost and operation risks,significant difficulty in controling the heating sufurization process of the shift catalyst. The operating effect of synthetic catalyst (whether domestic or imported) application in the coal to methanol industry is far lower than that of the natural gas industry. The Phase l 500,000t/a Coal to Methanol Plant of Henan Longyu Coal Chemical lndustry Co. ,Ltd. ,through upstream and downstream process optimization,has witnessed significant extension of the life cycle of the catalyst and great improvement of methanol output per unit of synthesis catalyst. By exploring the application of the new catalyst, the hidden risks confronting the shift unit are largely reduced.
