Abstract

FIELD: catalysts production, copper-zinc-aluminum catalyst production for low-temperature synthesis of menthanol and low-temperature conversion of carbon monoxide in particular. SUBSTANCE: aim is to create process of preparation of catalyst, that has high activity, stability and strength. Aim is realized by the fact, that catalyst is produced by settling of copper, zinc and aluminum nitrates by sodium carbonate under temperature of 50 - 80 C, pH equal to 6.0 - 8.0 and settling time period from 3 to 60 minutes. Settling of copper-zinc compound and copper-zinc-aluminum compound is exercised on preliminary settled zinc-aluminum stabilizer. Settling is exercised under continuous feeding of solutions in reactor system made of one or several reactors and under continuous removal of suspension from system. In the case average time of copper-zinc-aluminum compound staying in reaction zone does not exceed 60 minutes. EFFECT: method allows to produce highly active and thermally stable catalyst.

Цель изобретения - создание процесса приготовления катализатора, обладающего высокой активностью, стабильностью и механической прочностью. Эта задача решается тем, что предлагается способ получения катализатора путем осаждения азотнокислых солей меди, цинка и алюминия карбонатом натрия при 50-80°С, рН, равном 6,0-8,0, и времени осаждения от 3 до 60 мин.Осаждение медьцинкового или медьцинкалюминиевого соединения проводят на предварительно осажденный цинкалюминиевый стабилизатор. Кроме того, осаждение проводят при непрерывной подаче растворов в реакторную систему, состоящую из одного или нескольких реакторов, и непрерывном отводе суспензии из системы, причем среднее время пребывания медьцинкалюминиевого соединения в реакционной зоне составляет не более 60 мин. Предлагаемый непрерывный способ приготовления катализатора позволяет получать высокоактивный и термостабильный катализатор.The purpose of the invention is the creation of a catalyst preparation process with high activity, stability and mechanical strength. This problem is solved by the fact that the proposed method for producing a catalyst by precipitation of nitric salts of copper, zinc and aluminum with sodium carbonate at 50-80 ° C, a pH of 6.0-8.0, and a deposition time of 3 to 60 minutes. or a copper-zinc compound is carried out on a pre-precipitated zinc-aluminum stabilizer. In addition, the deposition is carried out by continuously supplying solutions to the reactor system consisting of one or more reactors and continuously withdrawing the suspension from the system, the average residence time of the copper-zinc compound in the reaction zone being no more than 60 minutes. The proposed continuous method of preparation of the catalyst allows to obtain a highly active and thermostable catalyst.
