The invention describes catalysts, methods of making catalysts, methods of making a microchannel reactor, and methods of conducting chemical reactions. It has been discovered that superior performance can be obtained from a catalyst formed by directly depositing a catalytic material onto a (low surface area) thermally-grown alumina layer. Improved methods of conducting oxidative dehydrogenations are also described.

Catalysts having catalytic material applied directly to thermally-grown alumina and catalytic methods using same; improved methods of oxidative dehydrogenation

The present invention provides catalysts, reactors, and methods of steam reforming over a catalyst. Surprisingly superior results and properties obtained in methods and catalysts of the present invention are also described. For example, a coated catalyst was demonstrated to be highly stable under steam reforming conditions (high temperature and high pressure of steam). Methods of making steam reforming catalysts are also described.

Steam reforming methods and catalysts

Steam reforming method

The invention describes microchannel apparatus and catalysts that contain a layer of a metal aluminide or are made in a process in which a metal aluminide layer is formed as an intermediate. Certain processing conditions have surprisingly been found to result in superior coatings. The invention includes chemical processes conducted through apparatus described in the specification. Other catalysts and catalyst synthesis techniques are also described.

Catalysts containing 30 weight percent or more platinum have surprisingly been discovered to possess superior stability and activity for catalyzing combustion reactions. The addition of rhenium improves catalyst performance in fuel lean conditions but has undesirable effects in fuel rich conditions. The invention provides integrated combustion microreactors, chemical systems utilizing these integrated combustion microreactors, methods of combustion, and methods of providing heat to endothermic reactions in integrated combustion microreactors.

Catalysts are described in which an active catalyst is disposed on a low surface area, oxide support. Methods of forming catalysts are described in which a Cr-containing metal is oxidized to form a chromium oxide layer and an active catalyst is applied directly on the chromium oxide layer. Methods of making new catalysts are described in which the surface is sonicated prior to depositing the catalyst. Catalyst systems and methods of oxidation are also described. The inventive systems, catalysts and methods are, in some instances, characterized by surprisingly superior results.

The present invention includes a supported catalyst for the reduction of nitrogen oxides (NO ) with a lower hydrocarbon. The supported catalyst comprising at least one active metal and at least one promoter metal attached to a support. The support may additionally include activated carbon. The promoter metals may be chosen from the lanthanide metals and the active metals may be chosen from palladium or platinum. The invention also includes a method of making the above mentioned catalysts and a method of using the catalysts to reduce nitrogen oxides (NO ) with a lower hydrocarbon.
