preparation example Construction

[0026] The preparation method of above-mentioned catalytic reforming regeneration gas dechlorination agent: comprise the following steps:

[0027] 1) Grind the chemical raw materials with the formula or chemical composition to be below 200 mesh, fully mix them evenly in the mixer, and prepare the liquid raw materials according to the weight ratio;

[0028] 2) Put the mixed powder into the rotating ball forming machine, through the continuous rolling of the ball forming machine, add water or liquid binder during the rolling process, so that the material rolls to form spherical particles, when the spherical particles are φ3~φ6mm , take it out and place it for 8-12 hours (health preservation);

[0029] 3) The placed spherical particles are placed in a drying room for drying, and then roasted in a rotary kiln or a roasting furnace at a roasting temperature of 400°C to 600°C for 4 hours, and then packaged to obtain the finished product.

Abstract

The invention discloses a catalytic reforming resurgent gas antichlor and it's preparing method. The antichlor comprises (by weight percent): Ca(OH)2 or CaO 30%-60%, MgCO3 or MgO 20%-30%, K2CO3 or KOH 10%-15%, foraminous zeolite or siallitic soil 5%-15%, alhydrogel powder or silicasol 5%-15%; The total of the raw materials are 100%. The suing range comprises: IFP-I type reforming regeneration craft, IFP- II type reforming regeneration craft, UOP type reforming regeneration craft and other types of reforming regeneration craft.

Description

technical field [0001] The invention relates to a dechlorination agent, in particular to a catalytic reforming regenerated gas dechlorination agent for removing HCl from mixed industrial gas under high temperature and variable temperature conditions and a preparation method thereof. Background technique [0002] In the petroleum refining industry, the activity of the reforming catalyst in the catalytic reforming process will gradually decline during use, and it needs to be regenerated regularly to restore its activity. During the regeneration process, the catalyst needs to be oxychlorinated with a regeneration medium organic chloride (such as carbon tetrachloride, etc.). During or after the oxychlorination process, part of the residual organic chloride is converted to HCl, the latter flows into the pipes and equipment of the subsequent system along with the regenerated gas, causing corrosion to the pipes and equipment, or polluting the atmosphere af...
