Description
Изобретение относитс к производству катализаторов дл процесса Клауса , npeflHa3Fra4eHHoro дл утилизации сероводорода из кислых газов с получением элементарной серы,The invention relates to the production of catalysts for the Claus process, npeflHa3Fra4eHHoro for utilizing hydrogen sulphide from acid gases to produce elemental sulfur,
Целью изобретени вл етс повышение активности катализатора за счет замещени в цеолите катионов натри на катионы металла, выбранного из группы, включающей никель, кобальт , цинк, кадмий, xpoMj при заданной степени обмена.The aim of the invention is to increase the catalyst activity by substituting sodium cations with metal cations in a zeolite for a metal selected from the group comprising nickel, cobalt, zinc, cadmium, xpoMj at a given exchange rate.
Пример 1, Дн приготовлени катализатора берут навеску цеолита МаХ с отношением SiO з Равным 2,35, прокаливают в течение б ч при охлаждают з эксикаторе и взвешиваигг, Затем из массы навески вычитают количество влаги и св зую- щеrOj рассчитывают количество г-эквExample 1, Day of catalyst preparation, weighed the zeolite MAX with the ratio SiO 3 equal to 2.35, calcined for 6 hours, while cooled from the desiccator and weighed. Then the amount of moisture is subtracted from the weight of the OO and calculated the g-eq.

Навеску соли раствор ют в 1, л дистиллированно воды так, чтобы соотношение зеса цеолит а к объему раствора соли было равкы.м 1:10.metal required for a given degree of exchange, and recalculated to the corresponding salt. A portion of the salt is dissolved in 1 liter of distilled water so that the ratio of zeolite xesa to the salt solution is equal to 1:10.
Цеолит помещают в колонку и медленно по капл м пропускают через него раствор соли при 70°С, затем тщательно про1-1ывают приготовленный каSUNaXThe zeolite is placed in a column and a solution of salt at 70 ° C is slowly added dropwise through it, then the prepared KSUNaX is carefully inspected.
