    • The invention provides a process for production of methanol from a feed stream rich in hydrogen carbon monoxide and carbon dioxide. The feed stream is converted to a converted process stream comprising methanol and small amounts of higher alcohols, aldehydes and ketones in the presence of a catalyst active in conversion of hydrogen and carbon monoxide into methanol. The converted process stream is cooled to a cooled process stream to 20-200°C. The cooled process stream is hydrogenated into a hydrogen ated process stream rich in methanol and depleted in aldehydes and ketones in presence of a hydrogenation catalyst. The catalyst is active in conversion of aldehydes and ketones into alcohols in a process stream rich in methanol and further comprising hydrogen, carbon monoxide and carbon dioxide. The hydrogenated process stream is cooled to a cooled, condensed process stream, and subsequently the cooled, condensed process stream is separated into a gas phase and a liquid crude methanol phase.
    • 本发明提供从富含氢一氧化碳和二氧化碳的进料流中生产甲醇的方法。 在催化剂存在下,将氢气和一氧化碳转化成甲醇,将原料流转化成包含甲醇和少量高级醇,醛和酮的转化过程物流。 将转化的工艺流冷却至冷却的工艺流至20-200℃。 在氢化催化剂的存在下,将冷却的工艺物流氢化成富含甲醇的氢气过程流,并将醛和酮消耗。 催化剂在富含甲醇的工艺流中将醛和酮转化为醇是有活性的,并且还包含氢气,一氧化碳和二氧化碳。 将氢化工艺流冷却至冷却的冷凝工艺物流,随后将冷却的冷凝工艺物流分离成气相和液体粗甲醇相。
