Abstract: A process for making a synthesis gas comprising H2 and CO in the presence of a reforming catalyst comprising a supported non-noble Group VIII metal catalytic component from a feed including a low molecular weight alkane, and preferably methane as in natural gas, O2 H2O and CO2 without catalyst deactivation is achieved by partially oxidizing and steam reforming the feed in the presence of the catalyst. The feed H2O to hydrocarbon carbon mole ratio is less than 2. The mole ratio of the combined feed CO2 and H2O to hydrocarbon carbon ranges from 0.5 - 2.5 and that of the feed H2O to CO2 ranges from 0.35 - 6. Synthesis gas having H2 to CO mole ratios less than 2:1 and even less than 1.5:1 are easily achieved with net CO2 consumption, which also makes the process environmentally beneficial.

Abstract: PROBLEM TO BE SOLVED: To provide a method with high cost-efficiency for removing a metal from a refinery supply-flow. SOLUTION: A petroleum flow is electrochemically demetallized by contacting a hydrocarbon-soluble metal containing petroleum flow and an aqueous electrolytic medium with a metal cathode having a low hydrogen overvoltage under an electrical current and a pH which allow demetallization of a petroleum flow. The voltage of the cathode is 0 to -3.0 V relative to SCE at a pH of 7-14. The material for the cathode is typically a stainless steel, chromium, copper and nickel.

Abstract: PROBLEM TO BE SOLVED: To provide an anode material with CO resistance, capable of oxidizing carbon monoxide by low potential energy, restraining undesirable overvoltage to a minimum, and forming from a stable precursor having platinum particles dispersed in non-stoichiometric hydrogen tungsten bronze. SOLUTION: A tungsten oxide source selected from among a group comprising tungsten peroxide, WO3 , H2 WO4 , WO2 , Na2 WO4 , and a mixture of them is deposited on the surface of platinum particles having a surface area in a range of about 100-500 m /g, a content in a range of about 10-40 wt.%, and a particle size of about 20-30 Å to form a composition, and the tungsten oxide source is reduced under a reducing atmosphere. Platinum carried on carbon, dispersed in non-stoichiometric hydrogen tungsten bronze, capable of depositing on the electrode material can be formed.
