氢化是油脂加工的主要催化过程,氢化过程的主要条件之一是具备符合一定要求的催化剂。实际上,油脂氢化主要是利用非均相催化剂,它们由具有较大表面的固体结晶物质所组成。实验指出,较大的接触表面不是决定非均相催化剂的唯一特征,因为对于某些反应或反应基团存在着特殊的接触,在这种情况下也表现了催化效应,有时甚至存在着催化剂和反应分子的化学亲合力。这表现了固体催化剂对反应物分子是选择性化学吸附。其中非均相催化氢化反应就应该具有化学吸附氢和不饱和化合物分子的
Hydrogenation is the main catalytic process of oil processing, hydrogenation process is one of the main conditions with certain requirements of the catalyst. In fact, the hydrogenation of fats mainly utilizes heterogeneous catalysts, which consist of solid crystalline materials with larger surfaces. Experiments have shown that larger contact surfaces are not the only determinants of heterogeneous catalysts because of the particular contact with certain reactive or reactive groups which in this case also exhibit catalytic effects and sometimes the presence of catalysts and Chemical affinity of the reaction molecule. This shows that the solid catalyst is selectively chemisorbed on the reactant molecules. The heterogeneous catalytic hydrogenation reaction should have a chemical adsorption of hydrogen and unsaturated compound molecules
