High mechanical strength economic and environmentally friendly desulphurization activated carbon and preparation method thereof

Abstract

The invention discloses a high mechanical strength economical and environmentally friendly desulfurization activated carbon, which is characterized by comprising the following raw materials by weight: 98-105 parts of wooden activated carbon, 35-40 parts of diatomite, 3-4 parts of zinc aluminate, 2.5-3.5 parts of manganese sulfate, 1-2 parts of sodium molybdate, 1-2 parts of cobalt dichloride, 2-3 parts of castor oil, 1-2 parts of butyl naphthalene sulfonate sodium, 2.5-4 parts of polyvinylpyrrolidone, 2-4 parts of waste rubber powder, 7-9 parts of lignite, 20-25 parts of corn cob, 27-31 parts of sand-grass straw, 4-6 parts of an adsorption aid and the right amount of water; by addition of the corn cob and the sand-grass straw, the specific surface area is increased, waste is turned into treasure; by addition of the waste rubber powder and other strength increase materials, the mechanical strength of the prepared activated carbon is high, the prepared activated carbon is not easy to collapse, economical and environmentally friendly, high in desulfurization efficiency, and simple in production process, can greatly reduce the operation cost of dry desulfurization, and is suitable for automobile exhaust gas treatment.

Description

technical field [0001] The invention relates to a desulfurization activated carbon and a preparation method thereof, in particular to an economical and environment-friendly desulfurization activated carbon with high mechanical strength and a preparation method thereof. Background technique [0002] As we all know, sewage treatment, papermaking, petroleum processing, chemical fertilizer manufacturing, chemical fiber manufacturing, and some chemical raw material manufacturing industries discharge a large amount of hydrogen sulfide and sulfur dioxide, which not only causes environmental pollution, but also easily leads to catalyst poisoning and deactivation, thus reducing industrial production. Sulfur emissions have become one of the major problems to be solved in today's world industrial production. [0003] Activated carbon with high specific surface area has a porous structure and can adsorb various organic and inorganic substances. It has the characteristics of large adsorp...

Problems solved by technology

[0004] Among the many desulfurization methods, one is activated carbon adsorption. Although activated carbon can adsorb a variety of acid gases, the price of activated carbon is relatively high, and the desulfurization efficiency is low, which increases the cost.
