  • Patent number: 9713804
    Abstract: The invention relates to a catalyst composition suitable for the non-oxidative dehydrogenation of alkanes having 2-8 carbon atoms comprising silico-zinc aluminate, wherein the relative molar ratios of the elements comprised in said composition are represented by SixZn1-xAl2O4, wherein x stands for a number in the range from 0.003 to 0.76. The invention also relates to a process for the preparation of said catalyst composition, to a process for the non-oxidative dehydrogenation of alkanes, preferably isobutane using said catalyst and to the use of said catalyst in a process for the non-oxidative dehydrogenation of alkanes.
    Type: Grant

  • Publication number: 20140039233
    Abstract: A catalyst composition suitable for conversion of alkanes having 3 to 12 carbon atoms per molecule to aromatic hydrocarbons, wherein the catalyst composition comprises: MN/MA/Ga-zeolite, wherein MN stands for one or more noble metals and MA stands for one or more alkali metals and/or alkaline earth metals. The MN/MA/Ga-zeolite is a zeolite comprising: 0.01-10 wt % of MN with respect to the total MN/MA/Ga-zeolite; 0.01-10 wt % of MA with respect to the total MN/MA/Ga-zeolite; and 0.01-10 wt % Ga with respect to the total MN/MA/Ga-zeolite.
