Abstract

A possibility of lowering the formation of trans-isomers during hydrogenation of vegetable oils over a low-loaded palladium catalyst supported on activated diatomite was studied. The comparison to the commercial nickel catalyst led to establish that the activated diatomite is a promising support of the catalyst for hydrogenation of plant oil. Palladium particles of 2–10 nm in size (3–6 nm particles predominated) were shown to be uniformly distributed over the support surface. It was shown experimentally that the Pd catalyst was more active and selective at low temperature than the nickel catalyst to provide two-fold decrease in the concentration of trans-isomers in the hydrogenated fat.

活化硅藻土负载钯催化剂上植物油的加氢

摘要

研究了在活化硅藻土上负载低负载钯催化剂上植物油加氢过程中降低反式异构体形成的可能性。与市售镍催化剂的比较表明，活化的硅藻土是该催化剂用于植物油氢化的有希望的载体。尺寸为2-10 nm的钯颗粒（以3-6 nm的颗粒为主）显示均匀分布在载体表面上。实验表明，在低温下，Pd催化剂比镍催化剂更具活性和选择性，从而使氢化脂肪中的反式异构体浓度降低了两倍。
