摘要： Dimethyldicyclopentadiene is continuously hydrogenated to tetrahydrodimethyldicyclopentadiene and then the latter is continuously isomerized to a missile fuel. Both the hydrogenation and the isomerization steps use a nickel on silica-alumina catalyst. The temperature of the hydrogenation is in the range of about 70.degree.-260.degree. C., and the temperature of the isomerization is in the range of about 200.degree.-280.degree. C. The space velocity of the hydrogenation is about 0.1 to about 2.0 volumes of the diene charged per volume of catalyst per hour and the space velocity of the isomerization is about 0.1 to about 3.0 volumes of the hydrocarbon charged per volume of catalyst per hour. The pressure range for hydrogenation is between about 200 psig to about 3000 psig and for isomerization between from about 10 psig to about 1500 psig. Hydrogen is present during the isomerization.

摘要： A naphtha upgrading process is provided which process utilizes a sulfated solid catalyst comprising (1) oxide or hydroxide of Group III or Group IV element, e.g. zirconium, and (2) a first metal comprising a metal or combination of metals selected from the group consisting of platinum, palladium, nickel, platinum and rhenium, and platinum and tin. The sulfated support is calcined prior to incorporation of the first metal and subsequent to said incorporation. The catalyst may further comprise (3) a second metal selected from the group consisting of Group VIII elements, e.g. iron. One embodiment of the invention further comprises (4) a third metal selected from the group consisting of Group V, VI and VII elements, e.g. manganese. Said second and third metals are added prior to the first calcination.
