TL;DR: In this article, a thermally autonomous microchannel this article for hydrogen production in the steam reforming of methanol has been designed and tested, which consists of an evaporator, a stirrer, and a microchannel catalytic unit (MCU) containing a catalyst deposited in short channels.

TL;DR: In this article, an operation of a microchannel reactor during the partial oxidation of methane has been studied and the deposition of a durable (Ni-Pt)/LaCeZrO catalyst on the Fecralloy microchannel plates working under thermocycling (up to 900°C) conditions up was developed.

Abstract: This paper reports the results of a study of a water–gas shift reaction over nickel–ceria catalysts with different metal loading. Within this study, the overall CO conversion and observed kinetic behavior were investigated over the temperature range of 250–550 °C in different reactor configurations (fixed-bed and microchannel reactors). The quasi-steady state kinetics of the CO water–gas shift reaction was studied for fractions of Ni-containing cerium oxide catalysts in fixed-bed experiments at lab-scale level using a very dilute gas (1% CO + 1.8% H2O in Не). A set of experiments with a microchannel reactor was performed using the feed composition (CO:H2O:H2:N2 = 1:2:2:2), representing a product gas from methane partial oxidation. The results were interpreted using computational models. The kinetic parameters were determined by regression analysis, while mechanistic aspects were considered only briefly. Simulation of the WGS reaction in the microreactor was also carried out by using the COMSOL Multiphysics program.

TL;DR: In this paper, a micro-channel reaction for catalytic oxidation of methanol to formaldehyde in a microchannel reactor (MCR) in view of the process intensification was investigated.
