Abstract: A method for chemically reducing carbon dioxide (CO2) with a red mud catalyst composition is provided includes introducing a gaseous mixture of CO2 and H2 into a reactor containing particles of the red mud catalyst composition. The method further includes reacting at least a portion of the CO2 and H2 in the gaseous mixture in the presence of the red mud catalyst composition at a temperature of 200 to 800°° C., and under a pressure ranging from 5 to 100 bar to form a gaseous product including a chemical reduction product of the CO2. A volume ratio of the CO2 to the H2 in the gaseous mixture is in a range of 1:10 to 10:1.

Abstract: A method for ammonia (NH3) decomposition to hydrogen (H2) and nitrogen (N2) includes introducing and passing a H2-containing feed gas stream into a reactor containing an industrial waste-based nickel (Ni-SMR) catalyst at a temperature of 500 to 900° C. to form a reduced Ni-SMR catalyst; introducing and passing an NH3-containing feed gas stream through the reactor in contact with the reduced Ni-SMR catalyst at a temperature of 100 to 1000° C. thereby converting at least a portion of the NH3 to H2 and regenerating the Ni-SMR catalyst particles to form a regenerated Ni-SMR catalyst, and producing a residue gas stream leaving the reactor; and separating the H2 from the residue gas stream to generate a H2-containing product gas stream.

Abstract: A method of preparing a metal-doped zeolite catalyst with a modified topology (e.g. a pillared zeolite or a delaminated zeolite), and a method of using thereof in a process for converting an alkyl-aromatic hydrocarbon stream to BTX (benzene/toluene/xylene), wherein an enhanced pore topology in the metal-doped zeolite catalyst determines a selectivity to transalkylation of trimethylbenzene to xylene, which in turn leads to a higher xylene yield. Various embodiments of the method of preparing the metal-doped zeolite catalyst, and the process for converting the alkyl-aromatic hydrocarbon stream to BTX are also provided.
