Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania katalizatora do wysokotemperaturowej konwersji tlenku węgla, który polega na wytrącaniu osadu prekursora, odmywaniu osadu, jego suszeniu i formowaniu, z dodatkiem grafitu, ostatecznej postaci katalizatora charakteryzuje się tym, że przygotowuje się roztwór siarczanu żelaza II, siarczanu miedzi i dichromianu sodu w temperaturze 60°C mieszając składniki przez 4 godziny, a następnie wprowadza się otrzymany wodny roztwór soli do roztworu wodnego zawierającego taką ilość NaOH aby pH po wymieszaniu składników w pierwszym etapie wynosiło 5 - 7 i w takich warunkach miesza się w temperaturze 60°C przez 30 minut, następnie dodaje NaOH w takiej ilości aby pH układu reakcyjnego w drugim etapie procesu otrzymywania prekursora wynosiło 9 - 11 i miesza się przez kolejne 30 minut utrzymując stałą temperaturę układu reakcyjnego 60°C, wytrąconą zawiesinę odfiltrowuje się, suszy w temperaturze 60 - 80°C, rozdrabnia, dodaje grafit i formuje katalizator nadając mu postać w tabletek przy czym zawartości Cr(VI) w gotowym wyrobie znajduje się na poziomie poniżej 0,05%.The subject of the application is a method of obtaining a catalyst for high-temperature conversion of carbon monoxide, which consists in precipitating the precursor sludge, washing the sludge, drying it and shaping, with the addition of graphite, the final form of the catalyst, characterized by the preparation of a solution of iron II sulphate, copper sulphate and dichromate of sodium at 60 ° C while mixing the ingredients for 4 hours, then the obtained aqueous saline solution is introduced into an aqueous solution containing such an amount of NaOH that the pH after mixing the ingredients in the first step is 5-7, and under such conditions, the mixture is stirred at a temperature of 60 ° C for 30 minutes, then NaOH is added in such an amount that the pH of the reaction system in the second stage of the precursor preparation process is 9-11, and it is stirred for another 30 minutes, keeping the temperature of the reaction system constant at 60 ° C, the precipitated suspension is filtered and dried at a temperature of 60-80 ° C, grinds it, adds graphite and forms a catalyst in tablet form, the content of Cr (VI) in the finished product being below 0.05%.
