METHOD OF HYDROGENATING CONTINUOUSLY RAW MATERIAL CONTAINING TRIGLYCERIDE

PROBLEM TO BE SOLVED: To provide a method of hydrogenating continuously a raw material containing triglycerides in a fixed bed reactor which is provided with a plurality of catalyst beds aligned in series and containing a hydrogenation catalyst.SOLUTION: Feed (1) of raw materials, a hydrogen-containing gas (2) and a diluent are caused to pass together through catalyst beds (3) to (7) under hydrogenation conditions. The flow of feed for raw materials and the flow of the hydrogen-containing gas are split into the same number of different split flows. The flows are caused to pass through one catalyst bed in such a way that the weight ratios of the diluent to the feed for raw materials are practically the same at inlets of the catalyst beds (3) to (7) and do not exceed 4:1. The method is preferably carried out at low temperatures and allows utilization of an existing apparatus owing to a low recirculation ratio. Since sufficiently excessive hydrogen is used, useful products are not lost through a decarbonization reaction. 【課題】直列に配列されかつ水素化触媒を含む複数の触媒床を有する固定床反応器システムにおいてトリグリセリド含有原材料を連続的に水素化する方法を提供する。【解決手段】原材料供給原料（１）、水素含有ガス（２）および希釈剤は、水素化条件で触媒床（３）〜（７）を一緒に通過させられる。原材料供給原料流並びに水素含有ガス流は、同数の異なる分流に分けられる。これらは、それぞれ、希釈剤対原材料供給原料の重量比が、全ての触媒床（３）〜（７）の入口において実質的に同じになりかつ４：１を超えないような方法で一つの触媒床中を通過させられる。特許請求された方法は、好ましくは、低い温度で行われ、低い再循環比に起因して既存装置の利用を可能にする。さらに、十分に過剰な水素が用いられ、その結果、脱炭反応を通じて有用な生成物が喪失しない。【選択図】図１
