摘要： A zeolite catalyst suitable for use in shape-selective hydrocarbon conversion processes. The catalyst is modified by incorporation therein of a hydrogenation-dehydrogenation functional metal, followed by gradient selectivation with an organosilicon compound under conversion conditions, wherein the gradient selectivation conditions are characterized by a progressive temperature gradient. The use of a progressive temperature gradient during the in situ selectivation procedure unexpectedly yields a catalyst in which the hydrogenation-dehydrogenation function is stabilized, thereby enabling long duration hydrocarbon conversion processes with low by-product make.

摘要： Living plants and animals synthesize and often accumulate a wide variety of organic materials having a molecular weight greater than 150. These include different chemical types such as natural hydrocarbons including rubbery substances, natural resins, and natural glycerides such as oils and fats. These substances, formed in the anabolic process, are collectively called "anabolites".This invention provides a process for catalytically converting certain anabolites to liquid hydrocarbons useful for the manufacture of fuels such as gasoline and chemicals such as para-xylene. Crystalline aluminosilicate zeolites having an effective pore size of greater than about 5 Angstrom units are useful catalysts.

The resultant catalyst is characterized by n-hexane sorption capacity at a temperature of 90.degree. C and a n-hexane partial pressure of 83 mm. of mercury which is at least 1 percent less than corresponding sorption capacity under identical conditions for the unmodified zeolite. Generally, the n-hexane sorption capacity for the described silica-modified zeolite, at the above specified conditions, is 5 to 60 percent less than that for the zeolite which has not undergone treatment to incorporate amorphous silica therein. The invention described herein also encompasses synthesis of the specified catalyst and use of the same in selectively converting lower monohydric alcohols and their ethers, especially methanol and dimethyl ether, to a hydrocarbon mixture rich in ethylene and propylene.

摘要： A novel use for sorbents involving the selective removal of heavy metals from liquid streams has been discovered. More specifically it has been discovered that these sorbents selectively remove alkyl lead moieties from gasoline. The sorbents are comprised of metal halides (preferably tin tetrachloride or antimony pentachloride) bonded to a suitable substrate through at least one amine or alkyl halide functional group. The sorbents can be effectively regenerated.
