This invention relates to a process for conducting a hydrocracking or a hydrotreating process in a microchannel reactor. This invention also relates to a process and apparatus for flowing a vapor and liquid into a plurality of microchannels in a microchannel processing unit.

Process and apparatus employing microchannel process technology

A new electroless plating approach to generate a porous metallic coating is described in which a metal is electrolessly deposited on a surface. Microparticles in the metal are removed to leave pores in the metal coating. Another method of forming electroless coatings is described in which a blocking ligand is attached to the surface, followed by a second coating step. The invention includes coatings and coated apparatus formed by methods of the invention. The invention also includes catalyst structures comprising a dense substrate and a porous metal adhered to the dense substrate, which is further characterized by one or more of the specified features.

Porous electrolessly deposited coatings

Methods for controlling series or series-parallel reactions are described. Novel microchannel apparatus having mesoporous structures adjacent to bulk flow paths are described. Methods of synthesizing formaldehyde from methanol are also described.

Microchannel apparatus comprising structured walls, chemical processes, methods of making formaldehyde

Integrated Combustion Reactors (ICRs) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.

Integrated combustion reactor and methods of conducting simultaneous endothermic and exothermic reactions

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

This invention relates to a process for converting ethylene to ethylene oxide comprising: flowing reactants comprising ethylene and oxygen or a source of oxygen in a microchannel reactor in contact with a catalyst to form a product comprising ethylene oxide, the reactants undergoing an exothermic reaction in the microchannel reactor; and transferring heat from the microchannel reactor to a heat exchanger.

Process for converting ethylene to ethylene oxide using microchannel process technology

Novel methods of electroless plating are described. Catalyst coatings can be applied within microchannel apparatus. Various reactions, including combustion and steam reforming, can be conducted over electroless catalyst coatings.

Electroless plating in microchannels

An apparatus is described which comprises at least one process microchannel having a height, width and length, the height being up to about 10 mm, the process microchannel having a base wall extending in one direction along the width of the process microchannel and in another direction along the length of the process microchannel; at least one fin projecting into the process microchannel from the base wall and extending along at least part of the length of the process microchannel; and a catalyst or sorption medium supported by the fin.

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

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.

Protected alloy surfaces in microchannel apparatus and catalysts, alumina supported catalysts, catalyst intermediates, and methods of forming catalysts and microchannel apparatus

Interior microchannels within microchannel apparatus are uniformly coated. Remarkably, these uniform coatings are formed from materials that are applied to the interior microchannels after an apparatus has been assembled or manufactured. Coatings can be made uniform along the length of a microchannel, in the corner of a microchannel, and/or throughout numerous microchannels in an array of microchannels. Techniques for tailoring the application of washcoats onto microchannels is also described.

Tailored and uniform coatings in microchannel apparatus

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.
