Abstract:
A process for producing ethylene from an ethanol feedstock comprises a step of subjecting the ethanol feedstock to a dehydration reaction in the presence of a supported heteropolyacid salt catalyst. The supported heteropolyacid salt catalyst includes a support and a heteropolyacid salt compound which is carried on the support and which is represented by a formula as defined herein.

Claim (Index 1):
A process for producing ethylene from an ethanol feedstock, comprising a step of subjecting the ethanol feedstock to a dehydration reaction in the presence of a supported heteropolyacid salt catalyst.\n wherein the supported heteropolyacid salt catalyst is prepared from a supported heteropolyacid catalyst which includes a support and a heteropolyacid carried on the support with a weight ratio of the heteropolyacid to the support in a range from 0.1:1 to 2.5:1; and wherein the supported heteropolyacid salt catalyst includes a support and a heteropolyacid salt compound which is carried on the support and which is represented by a formula selected from the group consisting of\n (M a n H 4-n )X a M d 12 O 40  \u2003\u2003Formula 1, \n (M b q H 3-q )X b M e 12 O 40  \u2003\u2003Formula 2, and \n (M c p H 6-p )X c M f 18 O 62  \u2003\u2003Formula 3, \n wherein: M a , M b , and M c  are independently selected from the group consisting of Cu, Ag, Au, Zn, Cd, and Hg; X a  is selected from the group consisting of Si and Ge; X b  and X c  are independently selected from the group consisting of P and As; M d , M e , and M f  are independently selected from the group consisting of Mo and W; n is an integer ranging from 1 to 4; q is an integer ranging from 1 to 3; and p is an integer ranging from 1 to 6.
