    Abstract: 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.

    Abstract: A catalyst is provided, which is especially applicable for the selective production of C.sub.2 -C.sub.3 olefins, comprising a crystalline aluminosilicate zeolite having a silica to alumina ratio of at least about 12, a constraint index, as hereinafter defined, within the approximate range of 1 to 12 and having contained within the interior crystalline structure thereof added amorphous silica in an amount of at least about 0.3 and preferably between about 0.5 and about 30 weight percent. 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.

    Abstract: 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.

    Abstract: There is provided a process for oligomerizing propylene by contacting propylene with silica modified zeolites. The modification of the zeolite with silica results in a product which is enriched in hydrocarbons falling within the boiling range of jet fuel (330.degree.-480.degree. F.) and diesel fuel (480.degree.-650.degree. F.). The zeolite may be ZSM-5, which may be modified by sorbing methylhydrogensilicone into the pores of the zeolite followed by calcination to convert the sorbed methylhydrogensilicone into amorphous silica.

    Abstract: Oligomers produced from lower alkenes by acidic zeolite catalyzed oligomerization can be converted to useful lubricant additives or lubricants by amidation and sulfonation of olefinic bonds in the oligomers by reaction with nitriles in the presence of strong acid catalyst whereby oligomer derivatives containing amide groups and sulfonic acid groups are produced. The products so produced from C.sub.20 + olefins exhibit favorable qualities as lubricants. The discovery is particularly applicable to the amidation and sulfonation of oligomers produced from lower olefins such as propylene by oligomerization using a ZSM-5 catalyst which has been surface deactivated.
