A method for producing a metal nitride and/or a metal carbide, a metal nitride and/or metal carbide optionally produced according to the method, and the use of the metal nitride and/or carbide in catalysis optionally catalytic hydroprocessing. Optionally, the method comprises: i) contacting at least one metal oxide comprising at least one first metal Mwith a cyanometallate comprising at least one second metal Mto form a reaction mixture; and, ii) subjecting the reaction mixture to a temperature of at least 300&#xb0; C. for a reaction period. Optionally, the metal nitride and/or metal carbide is a metal nitride comprising tungsten nitride.

Method for producing metal nitrides and metal carbides

Catalyst compositions with improved alkylation activity and corresponding methods for making such catalyst compositions are provided. The catalyst(s) correspond to solid acid catalysts formed by exposing a catalyst precursor with a zeolitic framework structure to a molten metal salt that includes fluorine, such as a molten metal fluoride. The resulting fluorinated solid acid catalysts can have improved alkylation activity while having a reduced or minimized amount of structural change due to the exposure to the molten metal fluoride. This is in contrast to fluorinated solid acid catalysts that are exposed to higher severity forms of fluorination, such as exposure to ammonium fluoride or HF. SnFis an example of a suitable molten metal fluoride.

Alkylation catalyst

Methods and systems for converting hydrocarbons including exposing a portion of a hydroperoxide-containing feed including tert-butyl hydroperoxide to a solid deperoxidation catalyst under decomposition conditions to form an oxidation effluent comprising tert-butyl alcohol, wherein the solid deperoxidation catalyst comprises a manganese oxide octahedral molecular sieve, are provided herein. Further methods and systems for converting the oxidation effluent to an alkylation product are also provided herein.
