阅读说明：本技术 用于减硫的再活化加氢处理的催化剂 (Catalyst for reactivation hydrotreating for sulfur reduction ) 是由 T·麦克休 J·西曼斯 B·维肖利 P·金坎农 J·W·汤普森 A·恩德林 于 2020-05-22 设计创作，主要内容包括：本文公开了用于提供用于硫回收操作中的尾气净化的催化剂的方法、系统和组合物。本公开的各个方面涉及获得在不是尾气处理过程的第一过程中使用的催化剂,然后在尾气处理过程中使用如此获得的催化剂。例如,催化剂最初可以是加氢处理催化剂。所公开的方法和系统的一个有利方面是用过的加氢处理催化剂的再利用减少了操作者因处置用过的催化剂而产生危险废物。最终,这有助于减少催化剂生命周期的环境影响。所公开的方法和系统还提供了经济上有吸引力的用于尾气处理的高性能催化剂来源,这有利于用过的催化剂产生者、催化剂提供者和催化剂消费者。(Disclosed herein are methods, systems, and compositions for providing catalysts for tail gas cleanup in sulfur recovery operations. Various aspects of the present disclosure relate to obtaining a catalyst for use in a first process that is not an exhaust gas treatment process, and then using the thus-obtained catalyst in an exhaust gas treatment process. For example, the catalyst may initially be a hydrotreating catalyst. One advantageous aspect of the disclosed methods and systems is that the reuse of the spent hydroprocessing catalyst reduces the hazardous waste to operators from disposing of the spent catalyst. Ultimately, this helps to reduce the environmental impact of the catalyst life cycle. The disclosed methods and systems also provide an economically attractive source of high performance catalyst for exhaust gas treatment, which is beneficial to used catalyst producers, catalyst providers, and catalyst consumers.)
