Abstract: A multilayer supported oxidative coupling of methane (OCM) catalyst composition (support, first single oxide layer, one or more mixed oxide layers, optional second single oxide layer) characterized by formula AaZbEcDdOx/support; A is alkaline earth metal; Z is first rare earth element; E is second rare earth element; D is redox agent/third rare earth element; the first, second, third rare earth element are not the same; a=1.0; b=0.1-10.0; c=0.1-10.0; d=0-10.0; x balances oxidation states; first single oxide layer (Zb1Ox1, b1=0.1-10.0; x1 balances oxidation states) contacts support and one or more mixed oxide layers; one or more mixed oxide layers (Aa2Zb2Ec2Dd2Ox2, a2=1.0; b2=0.1-10.0; c2=0.1-10.0; d2=0-10.0; x2 balances oxidation states; AaZbEcDdOx and Aa2Zb2Ec2Dd2Ox2 are different) contacts first single oxide layer and optionally second single oxide layer, and second single oxide layer (AO), when present, contacts one or more mixed oxide layers and optionally first single oxide layer.

Abstract: An OCM catalyst composition characterized by general formula AaLabEcDdOx; wherein A is an alkaline earth metal; wherein E is a first rare earth element; wherein D is a redox agent or a second rare earth element; wherein the first rare earth element and second rare earth element are different; wherein a is 1.0; wherein b is 0.01-10.0; wherein c is 0-10.0; wherein d is 0-10.0; and wherein x balances the oxidation states. The alkaline earth metal is selected from the group consisting of Mg, Ca, Sr, Ba, and combinations thereof. The first rare earth element and the second rare earth element can each independently be selected from the group consisting of Sc, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Y, Tb, Dy, Ho, Er, Tm, Yb, Lu, and combinations thereof. The redox agent is selected from the group consisting of Mn, W, Bi, Sb, Sn, Ce, Pr, and combinations thereof.

Abstract: A mixed oxide catalyst for the oxidative coupling of methane can include a catalyst with the formula AaBbCcDdOx, wherein: element A is selected from alkaline earth metals; elements B and C are selected from rare earth metals, and wherein elements B and C are different rare earth metals; the oxide of at least one of A, B, C, and D has basic properties; the oxide of at least one of A, B, C, and D has redox properties; and elements A, B, C, and D are selected to create a synergistic effect whereby the catalytic material provides a methane conversion of greater than or equal to 15% and a C2+ selectivity of greater than or equal to 70%. Systems and methods can include contacting the catalyst with methane and oxygen and purifying or collecting C2+ products.
