Abstract
Catalyst for dehydrogenating hydrocarbons, as manufactured by the process comprising: PA0 Admixing one or more iron compounds, chromium compounds and potassium compounds, in a definite range of relative proportions, PA0 Moistening and malaxing the resulting mixture while adding thereto a clayish material in such an amount as to obtain by reaction with the potassium compound, a proportion of 3 to 55% b.w. of potassium alumino-silicate in the final catalyst, PA0 Shaping the homogeneized resulting paste, drying and roasting it at about 870 - 1050.degree. C, the potassium compound being used in an amount greater than that liable to combine with the clayish material.
