制备链烷烃产品的方法
摘要：
本发明涉及由碳质原料制备链烷烃产品的方法，包括以下步骤：(a)将碳质原料部分氧化以获得包含氢和一氧化碳的混合物；(b)使用步骤(a)中获得的混合物进行费-托反应并回收来自所述费-托反应的废气和链烷烃产品；(c)使用0.5-1.5的蒸汽/废气摩尔比和包含铜和锌的催化剂，使至少一部分来自所述费-托反应的废气进行氢化反应；(d)接着使用镍基催化剂，进行转化反应；和(e)由至少一部分来自所述费-托反应的废气制备含氢气体。
摘要（英）：

The invention is a process for preparing a paraffin product from a carbonaceous feedstock comprising (a) partial oxidation of the carbonaceous feedstock to obtain a mixture comprising hydrogen and carbon monoxide, (b) performing a Fischer-Tropsch reaction using the mixture as obtained in step (a) and recovering an off-gas from the Fischer-Tropsch reaction and a paraffin product, (c) hydrogenating at least a part of the off-gas from the Fischer-Tropsch reaction using a steam/off-gas mol ratio in the range of between 0.7 and 1.5 and a catalyst comprising copper and zinc and/or a catalyst comprising copper and manganese, and (d) preparing a hydrogen comprising gas from at least a part of the off-gas from the Fischer-Tropsch reaction.
