説明

Ni-MgO catalysts were prepared from nickel nitrate and several kinds of basic magnesium carbonate, and the catalytic activities for the dealkylation of m-xylene with steam were measured at 450°C and 1atm pressure.<br>Necessary conditions to be satisfied to obtain active catalysts were as follows:<br>(i) An ethanol solution of nickel nitrate must be used in mixing the raw material of the catalyst support and nickel nitrate. The use of an aqueous solution gives the catalyst of poor activity.<br>(ii) The raw material of the catalyst support must be selected adequately. Among the raw materials used in this work, the group-1 basic magnesium carbonate (a mixture of MgCO3•3H2O and 4MgCO3•Mg (OH)2•4H2O) is preferable to the other type. The selection of the desirable raw material is easily achieved by D. T. A. experiments.
