Carbon Dioxide Methanation for [4] Intensified Reactors

The Kinetics of Methanation on Nickel Catalysts

An empirical rate equation was obtained for the methanation kinetics catalyzed by MCR-2X, a commercial catalyst prepared by Haldor-Topsoe. The studies were carried out in a fixed-bed reactor under differential conditions, and in a gradientless recycle reactor (Berry) over a range of total pressures, reactant concentractions (H2/CO ratios), and temperatures. The kinetics of methanation were foun...

Reactors, Kinetics, and Catalysis

( ) CO oxidation on Pt 100 was in®estigated at reactant pressures of 8 Pa using ellipsomicroscopy for surface imaging to monitor spatiotemporal pattern formation on the catalyst surface and mass spectroscopy to monitor the integral reaction rate. Three distinct temperature regions showing nonlinear phenomena were found. The first region, at 540 ] 615 K, is characterized by macroscopic, regular ...

The Reaction Kinetics of Dimethyl Ether. I: High- Temperature Pyrolysis and Oxidation in Flow Reactors

Dimethyl ether reaction kinetics at high temperature were studied in two different flow reactors under highly dilute conditions. Pyrolysis of dimethyl ether was studied in a variable-pressure flow reactor at 2.5 atm and 1118 K. Studies were also conducted in an atmospheric pressure flow reactor at about 1085 K. These experiments included trace-oxygenassisted pyrolysis, as well as full oxidation...
