Abstract

The invention relates to a preparation method for a bisphenol A hydrogenated catalyst. The preparation method comprises the steps that after a catalyst carrier is processed through a template agent, liquid RhCl3 is atomized and loaded onto the porous catalyst carrier, and after high-temperature reduction is conducted in the hydrogen atmosphere, the load type hydrogenated catalyst is obtained. The hydrogenated catalyst carrier is selected from one of Al2O3, TiO2 and SiO2. The template agent is selected from one of pyrrolidine, ethylenediamine and n-butylamine. According to the preparation method, the active component Rh is sprayed on the porous carrier in a vaporific mode, the obtained load type catalyst containing 1-10% of the Rh is suitable for hydrogenation of benzene rings and especially has good activity for preparing hydrogenated bisphenol A through bisphenol A hydrogenation; the aim product selectivity is good, and moreover, compared with a Ru system, the reaction load is improved by 30-50%; and the catalyst life still has the high activity after operation for 2000 hours.

Description

technical field [0001] The invention relates to a preparation method of a hydrogenation catalyst, which is used in the reaction of hydrogenating bisphenol A to prepare hydrogenated bisphenol A. Background technique [0002] Bisphenol A, also known as BPA, is used industrially to synthesize materials such as polycarbonate and epoxy resin. It has been used since the 1960s to make plastic feeding bottles, sippy cups for toddlers, and inner layers of food and beverage tubes. BPA is everywhere, from mineral water bottles, medical equipment to the inside of food packaging. Each year, more than 27 million tons of plastics containing BPA are produced worldwide. But BPA can also cause endocrine disorders, threatening the health of fetuses and children. Obesity from cancer and metabolic disorders is also thought to be involved. The European Union believes that baby bottles containing bisphenol A can induce precocious puberty, and since March 2011, the production of baby bottles co...
