Abstract: The invention in one embodiment is a nozzle device for coupling with a fluid distribution conduit for improving the distribution of an upward or downwardly flowing poly-phase mixture including at least one gas phase and at least one liquid phase, above at least one packed bed of granular solid or fluidized bed. The fluid distribution conduit for receiving liquid and gas phases has one or more lateral openings for flow over an upper portion of its height through which a gas phase can enter and has fluid distribution conduit having one or more lateral openings for flow over at least a lower portion of its height through which a liquid phase can enter the fluid distribution conduit. It also has at least one lower cross section for flow through which a mixture of gas and liquid communicate with a packed bed of granular solid or a fluidized bed.

Abstract: A photocatalytic method and apparatus employing a Holl-type mill for the direct production of methanol from methane and water comprising forming a water/methane emulsion and contacting the emulsion with a photocatalyst under conditions to react the methane and water to form methanol.

Abstract: The present invention is directed to a method for hydroprocessing Fischer-Tropsch products. The invention in particular relates to an integrated method for producing liquid fuels from a hydrocarbon stream provided by Fischer-Tropsch synthesis. The method involves separating the Fischer-Tropsch products into a light fraction and a heavy fraction. The heavy fraction is subjected to hydrocracking conditions, preferably through multiple catalyst beds, to reduce the chain length. The products of the hydrocracking reaction following the last catalyst bed, optionally after a hydroisomerization step, are combined with the light fraction. The combined fractions are hydrotreated, and, optionally, hydroisomerized. The hydrotreatment conditions hydrogenate double bonds, reduce oxygenates to paraffins, and desulfurize and denitrify the products. Hydroisomerization converts at least a portion of the linear paraffins into isoparaffins.

Abstract: A distributor assembly for a multi-bed, downflow catalytic reactor is disclosed. The distributor assembly is configured for disposal and fixable attachment between the inner surfaces of the walls of a multi-bed downflow cylindrical reactor wall and for disposal between vertically stacked catalyst beds within the reactor.
