Abstract

The invention discloses a desulfurizing agent for preventing a desulfurization enriching agent from hardening at a low temperature. The desulfurizing agent comprises the following raw materials in parts by weight: 50 parts of ferric oxide, 10 parts of basic zinc carbonate, 20 parts of pseudo-boehmite, 10 parts of diatomite, 2.0-2.5 parts of a binder, 5 parts of water glass and 3.0-3.5 parts of a lubricant. The invention further discloses a preparation method of the desulfurizing agent for preventing the desulfurizing rich agent from hardening at low temperature. The solid desulfurizing agent is prepared from the ferric oxide, the basic zinc carbonate, the pseudo-boehmite, the diatomite, the binder, the water glass and the lubricant, and the strength, the specific surface area and the water resistance of the desulfurizing agent are improved, so that the stability of the desulfurizing agent is improved.

Description

technical field [0001] The invention relates to the field of ammonia recovery from refinery sewage, in particular to a desulfurizer for preventing hardening of the desulfurization rich agent at low temperature and a preparation method thereof. Background technique [0002] Desulfurizers generally refer to agents that remove free sulfur or sulfur compounds in fuels, raw materials or other materials; in the control and treatment of pollutants, they mainly refer to the removal of sulfur oxides (including SO 2 and SO 3 ), various basic compounds can be used as desulfurizers. [0003] Ferric oxide and basic zinc carbonate are the main desulfurization components most widely used in the removal of hydrogen sulfide from gases. Generally, ferric oxide is mainly used under normal temperature conditions, and basic zinc carbonate is used under medium and high temperature conditions, and its desulfurization accuracy can reach ppm level, but under low temperature conditions, its desulfu...
