Abstract: Systems and methods for creating, managing, and analyzing marketing promotions are described. A bar code generator generates a bar code related to a deal offered by a merchant, wherein the deal includes deal data related to an offer to sell a good or service. The system also includes a bar code reader for reading the bar code. The remote server includes a deal database in which the deal data is stored. A deal transaction request process creates and transmits a deal transaction request via a telecommunications network from a customer computing device to the merchant computing device, and a deal transaction approval process receives the deal transaction request from the deal transaction request process and approves or rejects the deal transaction request. A notification process transmits an approval or rejection notification to the customer computing device as an alert that the deal transaction request has been accepted or rejected.

Abstract: A catalyst for selective hydrogenation of acetylene including a high surface area support material with a surface area at least about 150 m2/g and gold wherein the gold comprises from about 0.05 to about 5.0 weight percent of the catalyst and wherein the depth of penetration of the gold into the support material is such that at least about 90 percent of the gold is located within about 250 microns of the surface of the catalyst. A noble metal additive may also be included in the gold catalyst.

Abstract: A process for preparation of a selective hydrogenation catalyst including preparing a catalyst material containing palladium and preferably additional additive materials, prereducing the palladium material and the additional additive materials, storing the prereduced catalyst under a non-oxidizing material and distributing the prereduced catalyst in a shipping container under the non-oxidizing material to a customer for use in a selective hydrogenation reaction.

Abstract: A process for selective hydrogenation of acetylene during ethylene purification without in-situ prereduction utilizing a palladium/gold impregnated catalyst wherein the ratio of the gold to the palladium is from about 6:1 to about 50:1.
