Abstract
Description
a)第一の水素化触媒の粒子を、不飽和化合物が溶解している液相に懸濁させ、
b)水素を含有する気体の存在下、第一の水素分圧および第一の温度で、液相が並流で重力方向に対向して、充填気泡塔反応器を通じて送られ、
c)気泡塔反応器からの排出物が気液分離槽に供給され、
d)工程c)からの液相が十字流濾過に供給され、その際濃縮液と濾液が得られ、
e)濃縮液を工程b)に返送し、
f)水素を含有する気体の存在下、第二の水素分圧および第二の温度で、濾液が第二の水素化触媒床を介して導かれる
不飽和化合物を連続的に水素化するための方法によって解決される。
/m2h、好適には100〜500m3/m2h、とりわけ150〜300m3/m2hであり、気相の空塔速度は5Nm3/m2hより大きく、とりわけ10〜200Nm3/m2hである。充分に高い空塔速度を達成するために、工程d)からの濃縮液が返送される。
通常の織り方の金網製充填物(Kanthal社)を装填した気泡塔(長さ500mm、直径20mm)を備える、図1に示した装置を使用した。ワイヤの太さは0.1mm、編み目幅は1mm、編み目の傾斜角は垂直角に対して60゜であった。充填物の体積比表面積は2000m2/m3(金網の幾何学的配置の表面積、つまり理論表面積に基づき金網を滑らかな平面と考えた場合)であった。
実施例1に記載した装置を使用し、供給流としてデヒドロリスメラール(メタノール中で30質量%)を用いた。供給流に活性炭上に5%のパラジウムを含有するパラジウム−活性炭懸濁水素化触媒を懸濁した。反応は60℃、10barの水素圧下で連続的に行われた。懸濁触媒を有する液体および気体は200m3/m2hの速度で並流で重力方向に対向して反応器を通じて送られた。転換率は94%であった。空時収率は0.3L/(Lh)であった。
