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: A layered catalyst reactor system and process for hydrotreatment of hydrocarbon feedstocks. The layered catalyst system reactors comprise vertical bed layers including a demetallization catalyst layer, multiple layers of supported hydrotreating catalyst layer, and multiple alternating layers of supported hydrocracking catalysts and self-supported hydrotreating catalysts. The arrangement of the catalyst layers mitigates the risk of temperature run-aways, with improvements in hydrotreatment performance.

Abstract: Provided is a process of conducting a Baeyer-Villiger oxidation which comprises contacting a ketone and an oxidant in the presence of an Sn-DZ-1 catalyst to thereby oxidize the ketone to an ester. The Sn-DZ-1 catalyst comprises Sn heteroatoms on the external surface of the zeolitic material lattice framework, and B heteroatoms, or silanols created from boron hydrolysis, throughout the remainder of the lattice framework.

Abstract: The present invention is directed to the synthesis of novel stable open metal clusters by selective oxidation of bound ligands. The synthesis comprises, for example, using an amine based oxidant for decarbonylation of specific carbonyl ligands. The synthesis can also comprise further removal of a bound amine group by an acid. The resulting metal cluster contains a coordinatively unsaturated site comprising a carbonyl vacancy. The resulting metal cluster can be used as a catalyst in a variety of chemical transformations.
