Abstract:
A process for converting at least one C2 to C10 hydrocarbon to less saturated hydrocarbons, said process comprising the step of contacting at least one C2 to C10 hydrocarbon feed with (i) a catalyst having a general formula CraAbBc(O1âˆ’z(OH)2z)y, whereina+b+c=1; A is an element selected from the group consisting of Zn, Sn, Rh, Li, Na, K, Rb, Cs, Be, Mg, Ca, Sr and Ba; B is at least one element selected from the group consisting of Al, Si and Mg; wherein a is greater than 0.01 but less than 0.5; b is greater than 0.01 but less than or equal to 0.5; c is greater than 0.2 but less than or equal to 0.999; y is determined by the sum of the oxidation states of Cr, A and B individually multiplied by the corresponding stoichiometric coefficent a, b, or c, and said sum then divided by 2; and z is greater than or equal to 0 but less than or equal to 2; and (ii) a catalyst composition comprising rhodium and rare earth oxides.
