This catalyst includes a Cr-contg. active component deposited on an aluminum oxide support. To increase the activity, thermal stability, and mech. strength of the catalyst, it contains a compn. with a pyrochlore structure of general formula CeaCrbZrcO7, where a = 1.20-1.46, b = 0.51-0.83, c = 1.98-2.03, and γ-Al2O3 is the support with the following component ratio: CeaCrbZrcO7 9.5-10.6, and γ-Al2O3 as the balance. The method for prepg. the catalyst is also described.
