    摘要： The invention provides an improvement in the utilization of hydrocarbon feedstock by partial oxidation with oxygen to form a synthesis gas comprising carbon monoxide and hydrogen and subjecting the synthesis gas to a conversion process comprising an exothermic reaction. The oxygen is provided by air separation in which the feed air is at least partially compressed by work generated by expansion of a working fluid vaporized by indirect heat exchange with at least one of the synthesis gas and the exothermic reaction. The improvement is that the working fluid is preheated by indirect heat exchange with adiabatically compressed feed air, thereby improving the overall efficiency of the process and reducing capital costs compared with conventional generally isothermal feed air compression. Preferably, the gas conversion process is a catalytic hydrogenation to prepare paraffinic hydrocarbons (Fischer-Tropsch reaction), methanol or dimethylether.

    摘要翻译： 本发明通过用氧气部分氧化来提高烃原料的利用率，以形成包含一氧化碳和氢气的合成气并使合成气经历包含放热反应的转化过程。 通过空气分离提供氧气，其中进料空气至少部分地通过由与合成气体和放热反应中的至少一种的间接热交换而蒸发的工作流体的膨胀产生的功压缩。 改进之处在于工作流体通过与绝热压缩的进料空气进行间接热交换而被预热，从而与传统的通常等温进料空气压缩相比，改善了工艺的整体效率并降低了投资成本。 优选地，气体转化过程是用于制备链烷烃（费 - 托反应），甲醇或二甲醚的催化氢化。
