Novel efficient dechlorinating agent and preparation method thereof

Abstract

The invention discloses a novel efficient dechlorinating agent and a preparation method thereof. The novel efficient dechlorinating agent is prepared from active components selected from one or more of Na2CO3, CaCO3, CaO, MgO, CuO, ZnO and derivatives thereof, NH4CO3 serving as a porous auxiliary as well as carriers and auxiliaries selected from at least one of Al2O3, zultanite, kaolin or carclazyte by adding a modified Zn salt and a Ca salt as synergistic auxiliaries, adding an appropriate quantity of water according to the proportion, blending and mixing prior to extrusion molding, drying and roasting. The novel efficient dechlorinating agent has the advantages that the novel efficient dechlorinating agent is high in adsorption rate of both high-concentration HCl and low-concentration HCl at the normal temperature and high in dechlorinating presicion, and chlorine capacity is above 35%; the novel efficient dechlorinating agent is capable of subjecting HCl gas in every work section to efficient deep removal and catalytic reforming at the temperature of 300-600 DEG C, and breakthrough chlorine capacity can be above 65%; the solid dechlorinating agent is free of toxicity and corrosiveness and convenient and safe to operate manually, and treatment of the waste dechlorinating agent causes no pollution or damage to the environment.

Description

technical field [0001] The invention relates to the technical field of dechlorination of oil products, in particular to a dry dechlorination agent for removing HCl from various gases in a catalytic reforming section and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the national economy, the public's demand for oil products is increasing, and major oil companies continue to increase oil production and processing. Due to the continuous development of oil recovery technology, various chlorine-containing oil recovery chemical additives have appeared in oilfields. The addition of such oilfield chemical additives has greatly improved the efficiency of crude oil recovery, but it has had an impact that cannot be ignored on the refining and chemical industry. In the process of petroleum refining, organic chlorine in oilfield chemical additives is converted into HCl after prehydrogenation, which not only causes serious ...

Problems solved by technology

[0009] Although the above reports have carried out some research on dechlorination, the use conditions of the currently disclosed dechlorination agents are all relatively single, especially the temperature conditions are strictly limited. Generally, the dechlorination agents can only be used under normal temperature or high temperature conditions. Report on the preparation method and application of broad-spectrum dechlorination agent

At the same time, the existing catalytic reforming dechlorination agent still has unsatisfactory dechlorination effect in use, the lateral pressure strength of the dechlorination agent is insufficient, and the use conditions of the dechlorination agent are more restricted, which restricts the industry of the dechlorination agent.
