Abstract
1. Способ приготовления катализатора для получения элементарной серы из сероводородсодержащих газов в присутствии кислорода, включающий использование диоксида титана, соединения ванадия и оксида кремния, формование, термообработку, отличающийся тем, что, с целью увеличения активности, стабильности и механической прочности катализатора, в качестве соединения ванадия используют раствор оксалата ванадила, который смешивают с гелем или ксерогелем диоксида титана, полученную суспензию подвергают распылительной сушке, затем полученный продукт смешивают со связующим, содержащим 0,5-2,0%-ный раствор полиэтиленоксида и остальное - смесь, состоящая из золя оксида кремния и раствора оксалата ванадила, взятых в атомном соотношении Si:V, равном 1:6-29, формуют, сушат и подвергают термообработке при 450-500C.2. Способ по п.1, отличающийся тем, что, с целью получения катализатора с повышенной термической устойчивостью, перед распылительной сушкой в суспензию добавляют оксид сурьмы.1. The method of preparation of the catalyst to obtain elemental sulfur from hydrogen sulfide-containing gases in the presence of oxygen, including the use of titanium dioxide, vanadium compounds and silicon oxide, molding, heat treatment, characterized in that, in order to increase the activity, stability and mechanical strength of the catalyst, as a compound vanadium using a solution of vanadyl oxalate, which is mixed with a gel or titanium dioxide xerogel, the resulting suspension is subjected to spray drying, then the resulting suspension The product is mixed with a binder containing a 0.5-2.0% solution of polyethylene oxide and the rest is a mixture consisting of a silica sol and vanadyl oxalate solution, taken in an atomic ratio of Si: V equal to 1: 6-29, is molded, dried and heat treated at 450-500C.2. The method according to claim 1, characterized in that, in order to obtain a catalyst with high thermal stability, antimony oxide is added to the suspension before spray drying.
