Nissui-Topsoe Methanol-Synthesis Process. A schematic flow diagram [29] of the process offered by Haldor Topsoe of Denmark and Nihon Suiso Kogyo Company of Japan is given in Figure 3.17. The process is based on a copper-zinc-chrome catalyst that is active at 230—280 C and at a pressures of 100-200 atm. 

ATR(l) [Autothermal reforming] A process for making CO-enriched syngas. It combines partial oxidation with adiabatic steam-reforming. Developed in the late 1950s for ammonia and methanol synthesis. Further developed in the 1990s by Haldor Topsoe. 

Low-pressure methanol synthesis relies almost exclusively on catalysts based on copper, zinc oxide, and alumina. The catalysts are produced by ICI (now Johnson Matthay), Siidchemie (now Clariant), Haldor Topsoe, in the past also by BASF, and other chemical enterprises and contain 50-70 atomic % CuO, 20%-50% ZnO, and 5%-20% Al203. Instead of alumina, chromium oxide and rare earth oxides have also been used. The mixed oxide catalysts are usually shipped as 4-6 mm cylindrical pellets with specific surface area of 60-100 m2/g. The catalysts are activated in situ with dilute hydrogen, often derived from off-gases from synthesis gas...

Low-pressure methanol synthesis catalyst is a well-proven product that is commercially available from a number of reputable suppliers, including BASF, ICI, United Catalysts/Siid-Chemie, and Haldor-Topsoe. In the past, methanol synthesis catalyst was available from these suppliers as part of a process licensed to the end user, althou today this practice is no longer universally applied.
