Abstract: A method for reducing inorganic contaminant levels during supercritical water oxidation (SCWO) is provided. The method utilizes a fluidized bed reactor wherein inorganic contaminants in the water precipitate out onto the catalyst. The clean water is reclaimed after oxidation of organic contaminants and reduction of inorganic contaminant levels.

Abstract: A process for the production of a monoalkylated aromatic compound which minimizes the production of undesirable alkylating agent oligomers, while producing monoalkylaromatics in high yields. The process entails the combination of an alkylation reaction zone, a separations zone, and a transalkylation reaction zone wherein the alkylation catalyst and transalkylation catalyst are dissimilar and where the alkylation catalyst is comprised of noncrystaline silica-alumina material and the transalkylation catalyst is comprised of an acid-modified crystalline aluminosilicate material that is characterized as having a surface area of at least 580 m.sup.2 /g following acid washing after catalyst particle formulation.

Abstract: Superior aromatic alkylation and transalkylation performance is obtained with a novel catalytic composition comprising a hydrogen form mordenite incorporated with alumina. The superior performance is a direct result of the catalyst composition having a surface area of at least 580 m.sup.2 /g. A novel method of preparing a catalyst having a surface area of at least 580 m.sup.2 /g is characterized by contacting a formed catalytic composite with an acidic aqueous solution.

Abstract: Superior isomerization performance is obtained in an isomerization process employing a catalytic composition comprising a Group VIII noble metal and a hydrogen form mordenite incorporated with alumina. The superior isomerization performance is achieved using a catalyst composition having a surface area of at least 580 m.sup.2 /g. A novel method of preparing an isomerization catalyst having a surface area of at least 580 m.sup.2 /g is characterized by contacting a formed catalytic composite with an acidic aqueous solution prior to addition of the Group VIII noble metal. The isomerization process is particularly useful in the isomerization of a dimethylnaphthalene containing feedstock into a product that contains a higher concentration of the 2,6-dimethylnaphthalene isomer than did the feedstock.

Abstract: A method is disclosed for hydrocracking a hydrocarbon feedstock having a propensity to form polynuclear aromatic compounds without excessively fouling the processing unit. The hydrocracking method includes contacting the hydrocarbon feedstock with a crystalline zeolite hydrocracking catalyst, contacting at least a portion of the resulting unconverted hydrocarbon oil containing polynuclear aromatic compounds with an adsorbent which selectively retains polynuclear aromatic compounds and recycling unconverted hydrocarbon oil having a reduced concentration of polynuclear aromatic compounds to the hydrocracking zone.
