by John Bøgild Hansen (Senior Scientist, Haldor Topsøe A/S) Topsøe is a Danish company that develops catalysts and process technology for gas-to-liquid conversions. Hansen details Topsøe’s integrated conversion of synthesis gas to gasoline, which was developed to improve petroleum refining operations. By producing dimethyl ether (DME) and methanol in a single step, Topsøe avoids storage of intermediate methanol necessary in traditional methanol-to-gasoline processes, and improves conversion as a function of operating pressure. An interesting application of this technology involves co-processing aqueous bioethanol with synthesis gas, which can all be turned into gasoline with the Topsøe TIGAS process, and avoiding expensive ethanol distillation. Other applications involve actually generating synthesis gas from waste biomass, which Topsøe has tested in a project with Carbona, funded by the DOE.

Hansen’s presentation includes many pictures of process equipment and process flow diagrams, including some from the DOE project. There are also details on the gasoline synthesis series of reactions, and product data. READ MORE and MORE and MORE (US Department of Energy)
