Abstract: A Catalyst for reducing the nitrogen oxides in flue gases by a reducing agent and a catalytically active composition are described. The catalyst increases resistance to catalyst poisons such as arsenic trioxide. The composition contains 60-90% by weight of titanium, 10-30% by weight of molybdenum, and 0.2-10% by weight of vanadium, as their respective oxides. A very pure titanium dioxide having less than 500 ppm of calcium and less than 100 ppm of iron, being 60% in the anastase modification. It has a mean particle size of 10 to 100 nm, a mean pore radius of 10 to 30 nm and a BET surface of 10 to 80 m.sup.2 per gram. The catalyst is prepared by wet-grinding a suspension of the titanium dioxide with the vanadium pentoxide and molybdenum trioxide in stated proportions. The suspension is then dried and precalcined for several hours at 450.degree. to 550.degree. C. The precalcined material is comminuted to diameters smaller than 180 .mu.m.

Abstract: An automatic dishwasher detergent composition having improved chlorine stability is formulated as a linear viscoelastic, pseudoplastic, gel-like aqueous product of exceptionally good physical stability, low bottle residue, low cup leakage, and improved cleaning performance, Linear viscoelasticity and pseudoplastic behavior is attributed by incorporation of cross-linked high molecular weight polyacrylic acid type thickener. Potassium to sodium weight ratios of at least 1/1 minimize amount of undissolved solid particles to further contribute to stability and pourability. Control of incorporated air bubbles functions to provide the product with a bulk density of about 1.32 to 1.40 g/cc which roughly corresponds to the density of the liquid phase. Stearic acid or other fatty acid or salt further improve physical stability.

Abstract: A catalyst useful for hydroprocessing a hydrocarbon-containing oil contains at least one hydrogenation component on an amorphous, porous refractory oxide containing delta alumina. The catalyst is prepared by impregnating support particles having a narrow pore size distribution and a median pore diameter greater than about 185 angstroms with a solution containing a precursor of the hydrogenation components, followed by drying and calcining. The catalyst is useful for promoting a number of hydrocarbon hydroprocessing reactions, particularly hydrogenative desulfurization, demetallation and denitrogenation, and most particularly, hydrodemetallation of residuum-containing oils.

Abstract: The present invention relates to a novel route for the synthesis of methanol, and more specifically to the production of methanol by contacting synthesis gas under relatively mild conditions in a slurry phase with a catalyst combination comprising reduced copper chromite and basic alkali salts or alkaline earth salts. The present invention allows the synthesis of methanol to occur in the temperature range of approximately 100.degree.-160.degree. C. and the pressure range of 40-65 atm. The process produces methanol with up to 90% syngas conversion per pass and up to 95% methanol selectivity. The only major by-product is a small amount of easily separated methyl formate. Very small amounts of water, carbon dioxide and dimethyl ether are also produced. The present catalyst combination also is capable of tolerating fluctuations in the H.sub.2 /CO ratio without major deleterious effect on the reaction rate. Furthermore, carbon dioxide and water are also tolerated without substantial catalyst deactivation.
