InactiveCN101773768AImprove dechlorination activityHigh activityOther chemical processesAluminium silicatesPorosityCross-link
The invention relates to a dechlorinating agent used for removing HCl from a gas by using a dry method and a preparation method thereof. The dechlorinating agent is prepared from Na2CO3, CaCO3, CaO and MaO as active constituents, crosslinked bentonite as a porous auxiliary agent, and methyl cellulose as a foaming agent and an auxiliary extrusion agent through extrusion forming, drying and roasting. The cross-linked bentonite is prepared by exchanging large-size poly aluminum cation with small-size simple cation, so that the crosslinked bentonite has great porosity factor and large specific surface. The specific surface and the pore volume of the crosslinked bentonite are larger than those of non-crosslinked bentonite. By using the crosslinked bentonite as the porous auxiliary agent, the specific surface of the dechlorinating agent is enlarged, and the dechlorinating activity and the chlorosity of the dechlorinating agent are increased. The dechlorinating agent prepared by using the crosslinked bentonite has a pore volume of 0.3-0.4 mL / g, a specific surface of 70-90 m<2> / g and a crushing strength of 60-80 N / cm, not only has lower price than pseudo-boehmite and a molecular sieve, but also has simple preparation process, high dechlorinating activity and great low-temperature penetration chlorosity.

Through the use of the carrier and the binder, the prepared high-temperature dechlorinating agent has relatively high strength, relatively high water resistance, relatively high argillization resistance, relatively high temperature resistance, relatively high oxygen resistance and relatively high CO2 carbonation resistance; the penetrating chlorine capacity of the high-temperature dechlorinating agent reaches 40%, rapid loss of active components during use of the dechlorinating agent is reduced, harm and influence of loss of the active components of the dechlorinating agent on production of a reforming catalyst are reduced, and the dechlorinating agent which is stable to develop, high in chlorine capacity and long in service life is achieved.
