Procedure

An equimolar quantity of titanium n-butoxide [Ti(OC4H9)4 ] and zirconium chloride (ZnCl4) is dissolved respectively in an appropriate amount of anhydrous ethyl alcohol. After two ethyl alcohol solutions are mixed, the mixture is added dropwise to an excess of aqueous ammonia solution to obtain a white co-precipitate of titanium hydroxide with zirconium hydroxide. The co-precipitate is collected by filtration and then washed with de-ionized water until the solution is free of chloride ion. After being dried at 100° C. the co-precipitate is calcined in air at 500° C. for 2 hours to obtain the support of this example. 3.4 ml of 1.0M nickel nitrate solution is mixed well with the above support, the mixture is then dried at 90° C. whereby a supported catalyst which contains as 2wt% of nickel is obtained.
