Abstract

The invention relates to a purifying agent for sulfur, arsenic and phosphorus and a preparation method for the purifying agent. The invention is mainly to solve the problems of high bulk density and low adsorption capacity of a purifying agent in the prior art. The purifying agent for sulfur, arsenic and phosphorus provided by the invention comprises the following components in parts by weight: a)1 to 10 parts of aurichalcite; b) 10 to 50 parts of copper oxide; c) 10 to 60 parts of zinc oxide; d) 0.1 to 10 parts of nickel oxide; e) 0.1 to 5 parts of ferric oxide; and f) 0.01 to 3 parts of rare earth metal R. With a technical scheme of the invention, the purifying agent for sulfur, arsenic and phosphorus provided by the invention well solves the above-mentioned problems, and can be used for purification of natural gas, synthesis gas, light gaseous and liquid hydrocarbons, etc.

Description

technical field [0001] The invention relates to a sulfur, arsenic and phosphorus purifying agent and a preparation method thereof. Background technique [0002] Sulfur, arsenic, phosphorus and other impurities widely exist in raw materials such as natural gas, synthesis gas, coal gas, light gas and liquid hydrocarbons. The existence of these impurities will lead to poisoning and deactivation of many catalysts, greatly shorten the life of catalysts, and even lead to catalytic reaction It cannot be carried out normally; in addition, the impurities that have not been removed will enter the downstream synthetic products as the production progresses, which will bring a series of environmental and health problems. Therefore, efficient and high-precision removal of impurities such as sulfur, arsenic, and phosphorus is of great significance for protecting the main catalyst of downstream devices and improving the quality of downstream products at the same time. [0003] In general, ...
