Method of preparing a catalyst and catalyst prepared by the method

摘要

An improved catalyst for the high temperature steam reforming of hydrocarbons is provided. The method of preparing the catalyst includes the steps of: (1) impregnating a ceramic matrix with a solution containing soluble salts of the catalytic components and a delayed precipitating agent; (2) removing the matrix from the solution; (3) draining the matrix; (4) heating the matrix to a temperature suitable for the controlled hydrolysis of the precipitation agent, thus increasing the pH of the absorbed solution and bringing about deposition of the insoluble hydroxides within the pores; (5) calcining the precipitate within the pores to a mixture of the oxides; and (6) reducing the oxides.
