International Classification:

C07C 1/20

US Classification:

585357, 585358, 585639, 585640, 502 63, 502 64

Abstract:

A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8.

International Classification:

C25B 1/02

US Classification:

205342

Abstract:

A method is taught of introducing an alternating voltage between a first electrode and a second electrode in a mixture comprising a depolarizing agent. The method then alternates between forming hydrogen gas at the first electrode while simultaneously oxidizing a depolarizing agent at the second electrode and forming hydrogen gas at the second electrode while simultaneously oxidizing the depolarizing agent at the first electrode.

International Classification:

C25D 21/18

US Classification:

205 99

Abstract:

The method begins by forming a solution comprising catalyst precursors, electrolyte and a solvent. Electrodes are inserted into the solution comprising an anode electrode and a cathode electrode. Electrochemical deposition then occurs wherein a current is passed between the electrodes. In this method at least one additional step of: i) heating the solution prior to and during the electrochemical deposition; ii) increasing the concentration of the catalyst precursors in the solution to greater than 0.1 millimolar; iii) performing the electrochemical deposition by a pulsed current; and iv) adding chemical promoters to the solution.
