Short Contact Time Catalytic Partial Oxidation of Methane over Rhodium Supported on Ceria Based 3-D Printed Supports

Three different ceria containing catalyst supports and an alumina (control) support have been deposited with rhodium and used in the short contact time catalytic partial oxidation of methane. The goal of this paper is to compare reactor performance from powder catalyst studies to determine how they translate into structured high gas hourly space velocity catalysts operating at millisecond contact times. The supports were synthesized by 3-D printing of powders allowing for the first time the use of a catalyst support in the form of a monolith entirely composed of ceria. The ceria containing supports demonstrated some of the enhanced activity demonstrated as powders and showed superior methane conversion and hydrogen selectivity as compared to the alumina support. The use of 3-D printing to translate powder catalysts into structured supports is promising.
