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

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...
