Rapid reducing method of catalyst

Abstract

The invention relates to a rapid reducing method of a catalyst. In order to solve the problems of long catalyst reduction time and large hydrogen consumption quantity in the industrial production at present, the inventor provides the method comprising the steps of: in a reduction process of the catalyst, online-analyzing concentrations of hydrogen in gas at an inlet of a reduction furnace and gasin an outlet of the reduction furnace in real time, loading an online analysis result to a catalyst reduction control system, and regulating the reduction temperature of the reduction furnace by the reduction control system according to the change of the online-analyzed concentrations of the hydrogen. By using the method, the automatic reduction control of the catalyst reduction furnace can be realized, the whole reduction process can be monitored, the whole reduction time of the catalyst is reduced, the consumption of the hydrogen is reduced, thus the processing period of the catalyst is greatly shortened and the processing cost of the catalyst is reduced.

Description

technical field [0001] The present invention relates to a catalyst reduction method, more specifically, to a method for rapid catalyst reduction. Background technique [0002] The rapid development of modern chemical industry, especially coal and petrochemical industry, thousands of chemical raw materials and commodity production are closely related to the development of industrial catalysts. The existence of catalyst not only promotes technological innovation in industrial production, but also provides a broad space for human production activities. Most of the catalysts used in the petrochemical production process are solid catalysts, which are composed of three parts: carrier, auxiliary agent and active component, and the precursors of the active component are mostly metal salts. In industrial applications, most catalyst active components have catalytic activity only when metal atoms are supported on the carrier. Therefore, it is necessary to decompose the metal salt load...
