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

摘要

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.
