Abstract: The present disclosure refers to systems and methods for efficiently converting a C1-C3 alkane such as natural gas to a liquid C2-C10 product and hydrogen. Generally, the process comprises flowing the C1-C3 alkane through a plurality of tubes within a vessel wherein the tubes house a catalyst for converting the C1-C3 alkane to the liquid C2-C10 product and hydrogen. The C1-C3 alkane is heated under suitable conditions to produce the liquid C2-C10 product and hydrogen. Advantageously, the C1-C3 alkane is heated by burning a fuel outside the tubes in fuel burning nozzles configured to transfer heat from the burning through the tubes.

Abstract: Methods for regenerating spent catalysts, including spent catalysts used in in the catalytic conversion of a hydrocarbon feedstock. The method and associated processes comprising the method are useful to recover spent catalysts used in the petroleum and chemical processing industries. The method generally involves the use of an aqueous leaching solution to leach catalytically active metals from the spent catalyst so that solid carbon built up on the catalyst may be separated from the catalyst metals. The recovered catalyst metals, or a catalyst formed therefrom, may then be re-used in a catalytic conversion process.

Abstract: The present disclosure refers to systems and methods for producing hydrogen among other products. In some embodiments the methods comprise sequentially conducting a cracking step in a fixed bed mode and conducting a flowing step in a fluidized bed mode. Such sequential processes may result in a number of advantages including, for example, regenerating the catalyst during the fluidized bed mode in a manner such that beneficial heat is generated for use in the endothermic cracking step.

Abstract: A process for removing heavy polycyclic aromatic contaminants from a hydrocarbon stream using a quinolinium ionic liquid is described. The process includes contacting the hydrocarbon stream comprising the contaminant with a hydrocarbon-immiscible quinolinium ionic liquid to produce a mixture comprising the hydrocarbon and a hydrocarbon-immiscible quinolinium ionic liquid comprising at least a portion of the removed contaminant; and separating the mixture to produce a hydrocarbon effluent having a reduced level of the contaminant and a hydrocarbon-immiscible quinolinium ionic liquid effluent comprising the hydrocarbon-immiscible quinolinium ionic liquid comprising at least the portion of the removed contaminant.
