    Abstract: A process includes flowing a catalyst composition comprising catalyst particles into a radial flow moving bed reactor, wherein the catalyst particles move by gravity through the radial flow moving bed reactor to an exit point of the radial flow moving bed reactor, wherein the catalyst particles form a moving catalyst bed in the radial flow moving bed reactor, flowing a light hydrocarbon feed stream comprising C1 to C3 alkanes into the radial flow moving bed reactor in a manner so that the light hydrocarbon feed stream flows radially inward or radially outward through the moving catalyst bed and thereby contacts the catalyst particles under reaction conditions to produce a product effluent stream comprising a C2 to C10 hydrocarbon product and hydrogen, and flowing the product effluent stream from the radial flow moving bed reactor.

    Abstract: A process is provided for removing organic chlorides from glyceride oil. The process includes the steps of (a) reacting a glyceride oil comprising organic chlorides with a liquid aqueous system at a temperature of at least 80° C. to form a treated glyceride oil and (b) separating the treated glyceride oil from the liquid aqueous system. The treated glyceride oil has a reduced concentration of organic chlorides compared to the glyceride oil reacted in step (a).

    Abstract: A process for reducing TAN of hydrocarbon feed oil, comprising: a. combining alkaline earth metal, in an aqueous solution having a pH of 10 to 14, with the hydrocarbon feed oil to make a mixture; b. vigorously mixing the mixture; c. precipitating a metal-naphthenate salt; and d. removing the metal-naphthenate salt to reduce the TAN by 50 to 100%; wherein a weight ratio of the hydrocarbon feed oil to the aqueous solution is from 0.25:1 to 20:1. Also, a process for reducing TAN, comprising: a. combining an inorganic alkaline earth metal salt having a water solubility at 20° C. from 35 to 150 g/100 g water, in an aqueous solution having a pH of 10 to 14, to make a mixture; b. precipitating a metal-naphthenate salt; c. collecting the metal-naphthenate salt at an interface between an oil phase and an aqueous phase; and d. removing the metal-naphthenate salt.

    Abstract: A method includes combusting a fuel stream in a combustion unit in the presence of a first oxygen enriched carbon dioxide stream received from an anode of an electrolyzer to generate a hot flue gas stream comprising carbon dioxide, steam, unconsumed oxygen, NOx and SOx, cooling the hot flue gas stream in a heat exchanger by supplying a water stream to the heat exchanger as a heat transfer medium to generate a cooled flue gas stream effluent, processing the cooled flue gas stream effluent in one or more separation units to generate a carbon dioxide rich gas stream and a carbon dioxide lean gas stream, and passing the carbon dioxide rich gas stream to the anode of the electrolyzer to generate a second oxygen enriched carbon dioxide stream for sending to the combustion unit.

    Abstract: A reactor uses catalyst blocks for conversion of light hydrocarbons to hydrogen and to liquid hydrocarbons. The catalyst blocks stacked on top of one another within the reactor facilitate conversion of the light hydrocarbons. Electric heaters can be arranged in a variety of orientations within the reactor to supply heat for the conversion reaction. Alternatively, the catalyst blocks can be located within reaction tubes within the reactor and heated by combustion of a fuel adjacent to the reaction tubes. When operated in a regeneration mode, coke that accumulates within the reactor is removed by oxidation.
