Abstract

Przedmiotem zgłoszenia jest promotowany katalizator cynkowy parowej konwersji tlenku węgla, który charakteryzuje się tym, że prekursor katalizatora jest mieszaniną hydroksywęglanów cynku, glinu i ewentualnie miedzi, w którym to prekursorze stosunek molowy Cu/Zn mieści się w zakresie od 0 do 0,8, korzystnie od 0 do 0,2 a stosunek molowy (Cu+Zn)/Al mieści się w zakresie od 0,5 do 0,9, korzystnie od 0,6 do 0,8, zaś finalny katalizator zawiera promotory w postaci metali I grupy układu okresowego o sumarycznym stężeniu w zakresie od 0,1 do 10,0% wag. Przedmiotem zgłoszenia jest też sposób otrzymywania katalizatora, który polega na tym, że syntezę prekursora katalizatora, będącego mieszaniną hydroksywęglanów cynku, glinu i ewentualnie miedzi, prowadzi się poprzez wytrącanie a następnie filtrację wodnej zawiesiny prekursora, jego suszenie i kalcynację prowadzącą do uzyskania formy tlenkowej katalizatora, którą po rozdrobnieniu i ewentualnie zarabianiu ze środkiem zmniejszającym tarcie i z wodnym roztworem węglanu i/lub wodorotlenku metalu I grupy układu okresowego formuje się w kształtki o średnicy zewnętrznej okręgu opisanego na przekroju mieszczącej się w zakresie od 1 do 12 mm, a następnie suszy i ewentualnie impregnuje wodnym roztworem węglanów metali I grupy i suszy otrzymując produkt końcowy.The subject of the application is a promoted zinc catalyst of steam conversion of carbon monoxide, which is characterized in that the catalyst precursor is a mixture of zinc, aluminum and possibly copper hydroxycarbonates, in which precursor the Cu / Zn molar ratio ranges from 0 to 0.8, preferably from 0 to 0.2 and the molar ratio (Cu + Zn) / Al is in the range of 0.5 to 0.9, preferably 0.6 to 0.8, and the final catalyst contains promoters in the form of metals of group I of the system periodic with a total concentration in the range of 0.1 to 10.0 wt. The subject of the application is also a method of obtaining a catalyst, which consists in the fact that the synthesis of a catalyst precursor, which is a mixture of zinc, aluminum and possibly copper hydroxycarbonates, is carried out by precipitation and then filtration of the aqueous suspension of the precursor, its drying and calcination leading to obtaining the oxide form of the catalyst, which, after crushing and possibly earning with a friction reducing agent and with an aqueous solution of metal carbonate and / or hydroxide of the first group of the periodic table, is formed into shaped pieces with an outer diameter of the circle described on the cross-section in the range from 1 to 12 mm, and then dried and possibly impregnated aqueous solution of Group I metal carbonates and dried to obtain the final product.
