Abstract: A system for removing methane oxidation catalyst (MOC) poisons from an exhaust gas including a methane abatement unit that may receive the exhaust gas having methane (CH4)and the MOC poisons. The methane abatement unit includes a guard bed that may remove the MOC poisons from the exhaust gas and may generate an intermediate exhaust gas having the CH4 and devoid of the MOC poisons. The guard bed includes a MOC poisons capturing component having a first transition metal oxide, an aluminum oxide (Al2O3) support material, and a dolomite-derived support material. The methane abatement unit also includes a MOC bed fluidly coupled to and positioned downstream from the guard bed. The MOC bed includes a MOC and may remove CH4 from the intermediate exhaust gas to generate a treated exhaust gas having less than approximately 200 parts per million volume (ppmv) CH4.

Abstract: Implementations of the disclosed subject matter provide a process for the aromatization of a methane-containing gas stream that includes contacting the methane-containing gas stream in a reaction zone of an aromatization reactor comprising an aromatization catalyst and a zirconium hydrogen acceptor under methane-containing gas aromatization conditions to produce a product stream comprising aromatics and hydrogen, wherein at least a portion of the produced hydrogen is bound by the zirconium hydrogen acceptor in the reaction zone and removed from the product and the reaction zone as zirconium hydride, and wherein the weight ratio of zirconium hydrogen acceptor to the aromatization catalyst is at least 1:1.

Abstract: Implementations of the disclosed subject matter provide a process for the aromatization of a methane-containing gas stream that includes contacting the methane-containing gas stream in a reaction zone of an aromatization reactor comprising an aromatization catalyst and a titanium hydrogen acceptor under methane-containing gas aromatization conditions to produce a product stream comprising aromatics and hydrogen, wherein at least a portion of the produced hydrogen is bound by the titanium hydrogen acceptor in the reaction zone and removed from the product and the reaction zone as titanium hydride, and wherein the weight ratio of titanium hydrogen acceptor to the aromatization catalyst is at least 1:1.
