Способ позвол ет повысить активность КТ-сорбента в 1,5-2 раза, сократить количество сточных вод и врем приготовлени КТ на стади х сушки и прокалки . 1 табл.This invention relates to catalytic chemistry, in particular, to the preparation of a catalyst (QD) adsorbent for the purification of hydrocarbon gases from sulfur compounds. The goal is to increase the dynamic activity of the CT sorbent and reduce the amount of wastewater. Preparation of QT-sorbent containing iron oxide on active carbon involves impregnation of the carrier with a solution of iron salt and hydrolysis of the applied salt. Hydrolysis is carried out with gaseous ammonia diluted to contain it in a stream of 10-50% by volume, washed, and the drying and calcining steps are carried out in a stream of inert gas or under vacuum. The method makes it possible to increase the activity of the CT sorbent by 1.5–2 times, to reduce the amount of wastewater and the time of preparation of the QD at the stages of drying and calcining. 1 tab.

The resulting product is placed in a reactor and passed through a layer of coal diluted with argon (or nitrogen) to 50 vol.%, Ammonia is gaseous at room temperature until the breakthrough. Then the catalyst is washed from ammonium chloride with distilled water until the chlorine ion content in the wash water is less than 0.01 g / l and the catalyst is dried at 80-90 ° C in vacuum for 0.5 h. The calcining is carried out in vacuum at 180 ° C for 2 hours
