    摘要: The present invention relates to an apparatus for producing alcohols from olefins, comprising: a hydroformylation reactor wherein aldehydes are produced from olefins; a catalyst/aldehydes separator; a hydrogenation reactor wherein the aldehydes are hydrogenated to produce alcohols; and a distillation column. The hydroformylation reactor is equipped with a distributor plate, which has a broad contact surface for providing sufficient reaction area for reactants such as olefins and synthesis gas, and allows the reaction mixture to circulate and mix sufficiently, which contribute to excellent efficiency in terms of production of aldehydes. In addition, the hydrogenation reactor suppresses sub-reactions to improve the production yield of alcohols.
