The examination for industrialization of MgO-CaO-Al2O3-NiO system catalyst and the betterment of this catalyst in using for the catalytic cracking of heavy oil and the partial combustion reaction of naphtha was carried out. As the results, the following facts was clarified. 1) In the case of catalytic cracking of heavy oil by using MgO-CaO-Al2O3-NiO sistem catalyst, the town gas of calorific values of 5000-5500 kcal/m3 and hydrogen content of 40% or more was produced under the conditions of reaction temperature of 900-950°C, space velocity of 1.0, steam/oil ratio of 1.0 and thermal yields of 700 JHU or more as shown Table 6. 2) In the case of partial combustion reaction of naphtha by using the betterment catalyst, the town gas of calorific values of 3500kcal/m3 and hydrogen contents of 35% was prodused under the conditions of air/oil ratio (m3/1) of 1.0 and thermal yields of 700 JHU as shown in Table 7. 3) MgO-CaO-Al2O3-NiO system catalyst and the betterment catalyst as the basic nickel catalyst for the catalytic cracking of heavy oil and the partial combustion reaction of naptha were succeeded for industrial use.
