Application of hot-wire anemometry for experimental investigation of flow distribution in micro-packed bed reactors for synthesis gas conversion
Dadgar, Farbod; Venvik, Hilde Johnsen; Pfeifer, Peter (Journal article; Peer reviewed, 2018)The knowledge of the flow distribution inside microstructured reactors is valuable e.g. for improving the reactor design, developing flow distributors, and optimizing the catalyst loading method. The applicability of the ... -
Catalyst Deactivation During One-Step Dimethyl Ether Synthesis from Synthesis Gas
Dadgar, Farbod; Myrstad, Rune; Pfeifer, Peter; Holmen, Anders; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2017)Catalysts for direct synthesis of dimethyl ether (DME) from synthesis gas should essentially contain two functions, i.e., methanol synthesis and methanol dehydration. In the present work, the deactivation of both functions ... -
Direct dimethyl ether synthesis from synthesis gas: The influence of methanol dehydration on methanol synthesis reaction
Dadgar, Farbod; Myrstad, Rune; Pfeifer, Peter; Holmen, Anders; Venvik, Hilde Johnsen (Journal article; Peer reviewed, 2016)Direct dimethyl ether (DME) synthesis from synthesis gas is studied with regard to potential effects of methanol dehydration on methanol formation and copper-based catalyst performance. For this, the influence of the ... -
Pd/CeO2 catalysts as powder in a fixed-bed reactor and as coating in a stacked foil microreactor for the methanol synthesis.
Phan, Xuyen Kim; Walmsley, John Charles; Bakhtiary Davijany, Hamidreza; Myrstad, Rune; Pfeifer, Peter; Venvik, Hilde Johnsen; Holmen, Anders (Journal article; Peer reviewed, 2016)Pd/CeO2 as a catalyst for methanol synthesis has been studied in a microreactor consisting of 14 structured foils in a fixed-bed laboratory reactor. Methanol synthesis was carried out at 80 bar and 300 °C with a syngas ...
