摘要： A catalyst composition suitable for catalytic cracking of a heavy hydrocarbon oil containing large amounts of metal contaminants is prepared by the steps of spray-drying an aqueous slurry containing a flash calcined alumina obtained by contacting an aluminum hydroxide prepared Bayer's process with a hot air of 350.degree.-700.degree. C. for 5 seconds or less, clay being predominantly composed of silica and alumina, a precursor of a siliceous inorganic oxide and a crystalline aluminosilicate; washing this particle until the alkali metal content therein is reduced to 1.0 wt % or less as oxide; and thereafter incorporating a rare earth component in the particle.

摘要： In a globoid worm type compressor or expander comprising a casing, a globoid worm rotor in the casing and pinions meshing with the worm rotor, provision is made to effect sealing between the thread of the worm and each tooth of the pinions. The arrangement is such that the pinion is mounted on its shaft with the intermediary of a resilient member so that each tooth may be slightly displaced in both circumferential and diametric directions whereby to adapt itself to the thread of the worm to provide gas-tight seal between the tooth and the thread of the worm.

摘要： A method for reducing power consumption in a liquid-cooled type rotary compressor wherein a mixture of gas compressed in at least one compression chamber and liquid for cooling, lubricating and sealing are separated from each other immediately after the mixture is delivered out of the compression chamber to a delivery chamber so that the gas and liquid are allowed to behave separately. Further comprising the step of regulating the amount of liquid injected into said compression chamber always when the compressor is in operation. The said delivery chamber has a structure and dimension suitable for separating liquid from gas.
