Abstract: A method is disclosed for converting waste organic materials into an innocuous product gas. The method comprises maintaining, in a pressure vessel, in the absence of oxygen, at a temperature of 250.degree. C. to 500.degree. C. and a pressure of at least 50 atmospheres, a fluid organic waste material, water, and a catalyst consisting essentially of reduced nickel in an amount sufficient to catalyze a reaction of the organic waste material to produce an innocuous product gas composed primarily of methane and carbon dioxide. The methane in the product gas may be burned to preheat the organic materials.

Abstract: A method for converting organic material into a product gas includes: a) providing a liquid reactant mixture containing liquid water and liquid organic material within a pressure reactor; b) providing an effective amount of a reduced metal catalyst selected from the group consisting of ruthenium, rhodium, osmium and iridium or mixtures thereof within the pressure reactor; and c) maintaining the liquid reactant mixture and effective amount of reduced metal catalyst in the pressure reactor at temperature and pressure conditions of from about 300.degree. C. to about 450.degree. C.; and at least 130 atmospheres for a period of time, the temperature and pressure conditions being effective to maintain the reactant mixture substantially as liquid, the effective amount of reduced metal catalyst and the period of time being sufficient to catalyze a reaction of the liquid organic material to produce a product gas composed primarily of methane, carbon dioxide and hydrogen.

Abstract: Disclosed are treatment methods for breaking emulsions of petroleum oil and salt water, fatty oil and water, and those resulting from liquefication of organic material. The emulsions are broken by heating to a predetermined temperature at or above about 200.degree. C. and pressurizing to a predetermined pressure above the vapor pressure of water at the predetermined temperature to produce a heated and pressurized fluid. The heated and pressurized fluid is contained in a single vessel at the predetermined temperature and pressure for a predetermined period of time to effectively separate the emulsion into substantially distinct first and second phases, the first phase comprising primarily the petroleum oil, the second phase comprising primarily the water. The first and second phases are separately withdrawn from the vessel at a withdraw temperature between about 200.degree. C. and 374.degree. C. and a withdraw pressure above the vapor pressure of water at the withdraw temperature.

Abstract: A method is disclosed for converting lignocellulosic materials contained in biomass and other feedstocks into a fuel gas. The method comprises maintaining, in a pressure vessel, at a temperature of 300.degree. C. to 450.degree. C. and a pressure of at least 100 atmospheres, lignocellulosic material and water, and amounts of alkali and reduced nickel catalysts sufficient to catalyze a reaction of the lignocellulosic material to produce a product gas composed primarily of methane, hydrogen and carbon dioxide.

Abstract: An improved reclamation process for treating petroleum oil and water emulsions derived from producing or processing crude oil is disclosed. The process comprises heating the emulsion to a predetermined temperature at or above about 300.degree. C. and pressurizing the emulsion to a predetermined pressure above the vapor pressure of water at the predetermined temperature. The emulsion is broken by containing the heated and pressurized fluid within a vessel at the predetermined temperature and pressure for a predetermined period of time to effectively separate the emulsion into substantially distinct first, second and third phases. The three phases are then separately withdrawn from the vessel, preferably without any appreciable reduction in temperature and pressure, and at least above a withdraw temperature of about 300.degree. and above the vapor pressure of water at the withdraw temperature.

Abstract: Alkali metal carbonates have been found to be effective catalysts for dehydrogenation of primary and secondary alcohols. The dehydrogenated products may be either predominantly ketones and aldehydes, depending on whether the feed alcohol is secondary or primary, or may be fuel gases. Lower reaction temperatures, in the neighborhood of 600.degree. C., tend to produce high yields of liquid products. Higher temperatures encourage production of fuel gases of high calorific value. When fuel gases are a desired product, a feedstock containing water, in addition to the alcohol, produces increased yields due to the simultaneous catalysis of the water-gas shift reaction.

Abstract: The present invention is an improvement in the water-gas shift reaction in which an aqueous solution of ammonia or an ammonia yielding compound serves as a catalyst to increase the rate of, as well as shift the equilibrium toward, the production of hydrogen. The ammonia yielding compounds are preferably ammonium hydroxide or the weak acid salts of ammonia. Water for the reaction may be supplied by the solvent for the catalyst so that a separate source of steam is not required.
