    • A process for the preparation of hydrocarbon products comprising the steps of (a) providing a synthesis gas comprising hydrogen, carbon monoxide and carbon dioxide; (b) reacting the synthesis gas to an oxygenate mixture comprising methanol and dimethyl ether in presence of one or more catalysts which together catalyse a reaction of hydrogen and carbon monoxide to oxygenates at a pressure of at least 4 MPa; (c) withdrawing from step (b) the oxygenate mixture comprising amounts of methanol, dimethyl ether, carbon dioxide and water together with unreacted synthesis gas and introducing the entire amount of the oxygenate mixture without further treatment into a catalytic oxygenate conversion step (d); (d) reacting the oxygenate mixture in presence of a catalyst being active in the conversion of oxygenates to higher hydrocarbons; (e) withdrawing an effluent from step (d) and separating the effluent into a tail gas, a liquid hydrocarbon phase containing the higher hydrocarbons produced in step.(d) and a liquid aqueous phase, wherein the pressure employed in steps (c) to (e) is substantially the same as employed in step (b).
    • 一种用于制备烃产物的方法,包括以下步骤:(a)提供包含氢气,一氧化碳和二氧化碳的合成气; (b)在一种或多种催化剂的存在下使合成气与包含甲醇和二甲醚的含氧混合物反应,所述催化剂在至少4MPa的压力下一起催化氢和一氧化碳与含氧化合物的反应; (c)从步骤(b)中取出含有甲醇,二甲醚,二氧化碳和水的含氧化合物混合物以及未反应的合成气,并将全部量的含氧化合物混合物引入催化氧化合物转化步骤(d)中, ; (d)在含氧化合物转化为高级烃的催化剂存在下使含氧化合物混合物反应; (e)从步骤(d)中取出流出物并将流出物分离成尾气,包含步骤(d)中产生的高级烃的液体烃相和液体水相,其中步骤(c)中使用的压力 至(e)基本上与步骤(b)中使用的相同。
