Description
  • Katalizatory gidroochistki na osnove geteropolivol'framata nikelya byli prigotovleny putem propitki ?-Al2O3 rastvorami kisloty H3PW12O40 i ee nikelevoi soli. Soderzhanie nikelya v katalizatorakh var'irovali dobavleniem soli Ni(NO3)2. Pokazano, chto rezul'tatom vzaimodeistviya aktivnogo komponenta s nositelem yavlyaetsya prisutstvie na poverkhnosti katalizatora iskhodnogo geteropolianiona, ego lakunarnogo analoga i nikel'zameshchennogo geteropolianiona. Gidroobesserivayushchaya aktivnost' katalizatora opredelyaetsya nalichiem v ego sostave smeshannoi fazy NiWS, kotoraya obrazuetsya v rezul'tate sul'fidirovaniya.
  • HDS katalyzátory na bázi heteropolywolframátu niklu byly připraveny impregnací roztokem H3PW12O40 a její nikelnaté soli. Obsah niklu byl regulován přidáním soli Ni(NO3)2. Bylo zjištěno, že výsledkem vzájemného působení aktivní složky a nosiče je přítomnost výchozího heteropolyaniontu, jeho lakunárního analogu a Ni heteropolyaniontu na povrchu katalyzátoru. Odsiřovací aktivita je určena obsahem směsné fáze NiWS, která vzniká při sulfidaci katalyzátoru. (cs)
  • HDS catalysts based on nickel heteropolytungstate were prepared by impregnation of the support (Al2O3) by a solution of H3PW12O40 and of its Ni salt. Content of nickel was controlled by addition of Ni(NO3)2. It was found out that the result of mutual action of the active component and the support is presence of the initial heteropolyanion, of its lacunar analog and of Ni heteropolyanion on the catalyst surface. HDS activity is determined by the amount of mixed NiWS phase which originates during sulfidation of the catalyst. (en)
