Abstract: Processes are provided for the removal of hydrogen from a mixture. The process can be performed by contacting a mixture comprising hydrogen, oxygen, and one or more organic compounds with a synthetic zeolite to produce water or steam. The synthetic zeolite can include Si and Al and has a SiO2:Al2O3 molar ratio of greater than 4:1, an 8-membered ring zeolite having a framework type of AEI, AFT, AFX, CHA, CDO, DDR, EDI, ERI, IHW, ITE, ITW, KFI, MER, MTF, MWF, LEV, LTA, PAU, PWN, RHO, SFW or UFI, a degree of crystallinity of at least 80% as measured by ASTM D535-197, and at least 0.01 wt % of at least one catalytic metal, based on a weight of the synthetic zeolite, where the at least one catalytic metal can include Ru, Rh, Pd, Ag, Os, Ir, Pt, Au, Mo, W, Re, Co, Ni, Zn, Cr, Mn, Ce, Ga, alloys thereof, or mixtures thereof. At least 95% of the catalytic metal can be disposed within a plurality of pores of the synthetic zeolite.

Abstract: This application relates to transfer hydrogenation between light alkanes and olefins, and, more particularly, embodiments related to an integrated olefin production system and process which can produce higher carbon number olefins from corresponding alkanes. Examples methods may include reacting at least a portion of the ethylene and the at least one alkane via transfer hydrogenation to produce at least a mixed product stream comprising generated ethane from at least a portion of the ethylene, unreacted ethylene, and an olefin corresponding to the at least one alkane.
