Embodiment 1

[0027] The impregnated modified activated carbon adsorbent loaded with sodium phthalocyanine cobalt sulfonate is prepared according to the same amount of impregnation as follows. First, weigh 11.4 g of sodium phthalocyanine cobalt sulfonate, add it into 80 ml of deionized water and dissolve it, and prepare solution I containing sodium phthalocyanine cobalt sulfonate. Add 2.3ml of 86% H in solution I 3 PO 4 . Then add 17.7ml of water to prepare sodium phthalocyanine cobalt sulfonate with a molar concentration of 0.2mol / L and PO 4 3- Solution II with a concentration of 0.20mol / L. Through preliminary experiments, the water absorption rate of activated carbon was measured to be 50%. Accurately weigh 100g of activated carbon, and according to the water absorption rate measured above, take 50ml of the above-prepared solution II, pour the solution into a container containing activated carbon, stir well, and mix evenly. After drying in the air, drying, roasting at 500°C for 8 ho...

Abstract

The invention relates to a active carbon desulphurization adsorbent loaded with cobalt phthalocyanine sulfonate and a preparation method thereof, and mainly solves problems that sulfur removal rate is low, and breakthrough sulfur capacity of desulfurizer is low in existing gas adsorption, desulphurization and purification technology. In the invention cobalt phthalocyanine sulfonate is employed as active ingredient and a small amount of phosphor is added for modifying the active carbon. In this way, the solid adsorbent is obtained. The problems of low sulfur removal rate, etc. are solved. The desulphurization adsorbent of the invention can be used in adsorption and purification of gas materials for removal of sulfur-containing compound.

Description

technical field [0001] The invention relates to an activated carbon desulfurization adsorbent loaded with phthalocyanine cobalt sulfonate and a preparation method thereof. Background technique [0002] h 2 S, carbonyl sulfide, mercaptan, sulfide and other sulfur-containing gas compounds widely exist in natural gas, oilfield associated gas, coke oven gas, coal gas, refinery gas, petroleum cracking gas, synthesis gas, water gas, semi-water gas and Claus method in the exhaust. As a common harmful and foul-smelling gas, most sulfides are highly toxic to humans and animals, and are flammable and explosive, easily corroding metal production equipment, and are poisonous to many catalysts. It is discharged into the air, pollutes the environment, and brings many adverse effects to people's production and life. In order to avoid its harm, under normal circumstances, the sulfur-containing raw gas needs to be desulfurized and purified in advance. [0003] As an important process of ...
