High-activity catalyst regenerative liquid and preparation method thereof, and resurrection device

Abstract

The invention relates to the technical field of deactivated catalyst regeneration, and particularly relates to a high-activity catalyst regenerative liquid and a preparation method thereof, and a resurrection device of a deactivated catalyst. The high-activity catalyst regenerative liquid includes the following components in parts by weight: 4-6 parts of an acid catalyst, 3-15 parts of a surfactant, 5-20 parts of a dispersant, 8-25 parts of a degradation agent, and 80-100 parts of a regenerative preparation liquid, wherein the regenerative preparation liquid includes an inorganic salt and an ethanol aqueous solution, the concentration of the inorganic salt is 0.1-2 mol / L, and the concentration of the ethanol aqueous solution is 20-60 wt%. The high-activity catalyst regenerative liquid has good effect on supplementing catalyst active ingredients, and the recovery degree of the catalyst activity after regeneration is high.

Description

technical field [0001] The invention relates to the technical field of deactivated catalyst regeneration, in particular to a high-activity catalyst regeneration liquid, a preparation method of the regeneration liquid, and deactivated catalyst revival equipment. Background technique [0002] Catalyst regeneration is the process of restoring the efficiency of a catalyst whose catalytic efficiency has declined. The regeneration process does not involve the disintegration of the overall structure of the catalyst, but only uses appropriate methods to eliminate those factors that lead to the decline of catalytic performance. [0003] In recent years, in order to prevent environmental pollution, reduce investment in reactors and regeneration facilities, and better restore activity, especially for sulfide catalysts used for hydrogenation and hydrocracking, a number of catalyst regeneration plants have been established to specifically treat catalysts External regeneration. After th...

AI Technical Summary

Problems solved by technology

After the regenerated catalyst is regenerated, its composition and structure cannot be completely restored to its original state. Therefore, the performance of the regenerated catalyst is generally lower than that of the new catalyst. After multiple regenerations, the performance characteristics deteriorate to the point that it cannot maintain normal operation or catalytic process. The economic benefit is lower than the specified index, which means that the catalyst life is terminated
