Abstract: A catalyst composition and process facilitates the oxidative reforming of low molecular weight hydrocarbons, such as methane, to other hydrocarbons having 2 or more carbon atoms (“C2+ compounds”). Compositions having a formula comprising a metal, tungsten, manganese and oxygen effectively catalyze the oxidative reforming of methane with a high rate of conversion and selectivity. Controlling feed gas flow and catalyst bed temperature controls the exothermic OCM reaction, avoiding runaway reactions or coking. A single or multiple reactor system can be utilized for the oxidative reforming reactions. Using two reactors in series, catalyst embodiments produced favorable yields of C2+ compounds, in the presence or absence of a distributed oxygen feed, and with or without interstage effluent cooling. Removal of desirable end products from the reactor effluent, followed by recycling of the residual effluent, increases the conversion to, and ultimate yield of desirable end product.

Abstract: Hydrogenated vegetable oil exhibiting superior thermal stability and containing reduced levels of saturates and trans fatty acids are produced using an activated hydrogenation catalyst and/or an improved hydrogenation process incorporating high shear. The use of a high shear mechanical device incorporated into the hydrogenation process as a reactor device is shown to be capable of enabling reactions that would normally not be feasible under a given set of reaction pressure and temperature conditions. For example, the hydrogenation process described herein enables a reduction of hydrogenation time, and operation at lower temperatures than current processes. The resulting hydrogenated vegetable oil is particularly useful in frying, confectionery baking, and other applications where a product with a low trans fat content or higher thermal stability is desirable. The hydrogenated oil produced may comprise less than 10 weight % of trans fatty acids with less than 5 weight % of linolenic acid (C18:3).

Abstract: A perovskite catalyst is prepared using a ceramic sol-sol methodology comprising preparing slurry in water of an alkaline earth metal salt, a powdered metal salt and a powdered transition metal oxide, adding a polymeric binder to form a paste, drying and comminuting the paste into a powder and heating the powder with a temperature profile to calcination temperatures. In one embodiment the slurry is formed of titanium oxide with barium carbonate and tin chloride in deionized water, and more specifically by a mixture according to Ba (1-0.05x)+TiO2+SnCl2(0.05x) where x is in moles. The perovskite catalyst is preferably used in a process for oxidative coupling of methane. Catalyst performance is enhanced through the addition of halides to the feed gas in the reaction.

Abstract: Waxes prepared from hydrogenated plant oils, such as castor, palm, and soybean, are used to prepare water based emulsions. The inventive waxes, obtained from naturally derived, renewable resources, were emulsified under anionic, cationic and nonionic conditions, producing emulsions having a solids content up to about 45% solids. When used to coat fibrous cellulosic articles, such as paperboard, the emulsions' performance was similar to emulsions containing petroleum-derived waxes. The inventive waxes have a low iodine value (between 2-5), and melting points between approximately 120-200 degrees F. (Mettler Drop Point). These waxes comprise a triglyceride whose fatty acids are predominantly stearic acid or ricinoleic acid.

Abstract: A catalyst and process for formation of hydrocarbons having carbon numbers of two or greater, the result of both oxidative coupling of methane (“OCM”), and other reforming reactions of OCM end products. An OCM catalyst has a structure represented by formula ABTiO3, wherein A is samarium or tin, B is barium; the reforming catalysts a composition represented by formula XYZ, wherein X is a metal from Group IA, Group IIA or Group VIIIA, or not present, Y a metal from Group VA, Group VIA, Group VIIA or Group VIIIA, Z chosen from oxygen, silica, silicalite and alumina. The inventive catalyst comprises an OCM catalyst and a reforming catalyst blended together; when used in a reactor effects an increased yield of hydrocarbons having a carbon number greater than 2 (in excess of 27%-30%, first pass rate of methane conversion about 50%) than occurs under OCM conditions alone.

Abstract: A process and catalyst for the partial oxidation of low molecular weight paraffinic hydrocarbons, such as methane, ethane, propane, naphtha, and natural gas condensates to form alkenes, such as ethylene, propylene and other valuable by-products. The process involves contacting the low molecular weight paraffinic hydrocarbon with the catalyst in the presence of oxygen or air and optionally steam. The catalyst has a perovskite-type crystalline structure, and lends itself to fixed and fluidized bed reactor configurations. The conversion process is less costly than conventional processes due to low pressure operation, the use of air and steam as a source of oxygen, and lower operating temperatures resulting in less coking, downtime, and reduced cost for materials of construction. Catalyst activity is extended and reactor downtime for catalyst regeneration is minimized by addition of chlorides and/or amines.
