Abstract: A process for converting a hydrocarbon charge stock into lower boiling, normally liquid hydrocarbon products which comprises reacting said charge stock and hydrogen at hydrocracking conditions in contact with a catalyst comprising an alumina-crystalline aluminosilicate composite, a Group VIB metal component and a Group VIII metal component. The catalyst is characterized by a method of preparation.

Abstract: A process for removing, by absorption, sulfur dioxide from a gaseous mixture such as a flue gas by scrubbing said mixture with an aqueous scrubbing solution containing an alkaline reagent such as sodium carbonate. The solution also has dissolved in it a quantity of silica which tends to precipitate when the pH of the solution is lowered by the absorption of the sulfur dioxide. The silica precipitated in this manner tends to form rock like deposits in the scrubbing device and associated equipment. If a water soluble basic salt of aluminum, such as sodium aluminate is added to the scrubbing solution prior to its use in the process, an aluminosilicate precipitate is formed which has a minimum deleterious effect.

Abstract: A method of catalyst manufacture. A calcined tin-containing refractory inorganic oxide support or carrier material is treated in contact with an aqueous solution of a basic reagent and thereafter impregnated with a Group VIII metal component to yield a catalytic composite of improved activity.

Abstract: An insoluble basic aluminum sulfate characterized by an SO.sub.3 /Al.sub.2 O.sub.3 mole ratio of from about 0.6 to about 0.4 and a particle size of from about 1 to about 10 microns is commingled with acidic silica sol to form a stable suspension which is convertible to spheroidal particles by the oil-drop method.
