The present invention provides a class of catalyst compounds that can safely and effectively release hydrogen gas from a chemical substrate without producing either noxious byproducts or byproducts that will deactivate the catalyst. The present invention provides catalysts used to produce hydrogen that has a satisfactory and sufficient lifespan (measured by turnover number (TON)), that has stability in the presence of moisture, air, acid, or impurities, promote a rapid reaction rate, and remain stable under the reaction conditions required for an effective hydrogen production system. Described herein are compounds for use as catalysts, as well as methods for producing hydrogen from formic acid and/or a formate using the disclosed catalysts. The methods include contacting formic acid and/or a formate with a catalyst as described herein, as well as methods of producing formic acid and/or a formate using the disclosed catalyst and methods for generating electricity using the catalysts described herein.

A catalyst structure includes a carrier having a porous structure composed of a zeolite type compound and at least one catalytic material existing in the carrier. The carrier has channels communicating with each other, and the catalytic material is a metal fine particle and exists at least in the channel of the carrier.

A process for preparing a syngas from a methane comprising gas includes reacting the methane comprising gas with an oxidising gas at an operating temperature in the range of 1150 to 1370° C. by means of non-catalytic partial oxidation. A hot raw syngas mixture having a methane content higher than the methane content in a state of thermodynamic equilibrium at the operating temperature applied is passed through a bed of methane oxidation catalyst for oxidising methane with steam formed in the non-catalytic POX into carbon monoxide and hydrogen. The methane oxidation catalyst has at least one catalytically active metal supported on a refractory oxide support material where soot particles present in the hot raw syngas mixture are retained. The retained soot particles are converted to carbon monoxide. Soot depleted syngas is recovered in a state of thermodynamic equilibrium.

A method for producing methanol includes obtaining reformed gas by subjecting raw material gas containing methane to partial oxidation reforming by use of oxygen; reducing a CO/CO.sub.2 ratio in the reformed gas; and obtaining produced gas containing methanol from the reformed gas with the reduced CO/CO.sub.2 ratio by using any of a fixed-bed reactor and an isothermal reactor.

Redox catalysts are provided for “low-temperature” methane partial oxidation in absence of gaseous oxidants. Methods of converting the methane to syngas using the catalysts are also provided. In some aspects, the conversion takes place at temperatures of about 400° C. to about 950° C. The methods can be used to convert methane to syngas containing carbon monoxide and hydrogen gas. In some aspects, the methods are carried out in a fixed bed reactor with reverse flow.

A hydrocarbon reforming catalyst for producing a synthesis gas containing hydrogen and carbon monoxide from a hydrocarbon-based gas, the hydrocarbon reforming catalyst containing a complex oxide having a perovskite structure including at least Ba, Zr, and Ru; and a hydrocarbon reforming apparatus that includes the hydrocarbon-reforming catalyst.

Provided herein are catalyst materials and processes for processing hydrocarbons. For example, doped ceria-supported metal catalysts are provided exhibiting good activity and stability for commercially relevant DRM process conditions including low temperature and long term operation.

Chemical processors are configured to reduce mass, work in conjunction with solar concentrators, and/or house porous inserts in microchannel or mesochannel devices made by additive manufacturing. Methods of making chemical processors containing porous inserts by additive manufacturing are also disclosed.

A process of dissociating ammonia into a dissociated hydrogen/nitrogen stream in catalyst tubes within a radiant tube furnace and an adiabatic or isothermal unit containing catalyst, along with downstream purification process units to purify the dissociated hydrogen/nitrogen stream into high purity hydrogen product.

The present invention relates to a monolith catalyst for carbon-dioxide/methane reforming and a method of manufacturing the same, and more particularly to a novel monolith catalyst for a reforming reaction having improved thermal durability, configured such that a sintering inhibiting layer is formed by coating the surface of a monolith support with at least one element selected from the group consisting of Group 2, 3, 6, 13, 15 and 16 elements among elements in Period 3 or higher and an active catalyst layer is formed on the sintering inhibiting layer, thereby preventing carbon deposition and catalyst deactivation due to deterioration even upon reaction at high temperatures.
