Selective hydrocarbon synthesis
The project 'selective hydrocarbon synthesis' has aimed at a demonstration of a new process for the production of high-octane gasoline from synthesis gas. The process is designated the Tigas process (Topsoe Integrated Gasoline Synthesis). The Tigas process is characterized by a large degree of integration of the three process steps involved, synthesis gas production, oxygenate synthesis and gasoline synthesis. The main idea is to eliminate costly interconnecting unit operations between the individual process steps. The integration is achieved by combining the two process steps, methanol synthesis and gasoline synthesis into one single synthesis loop without any isolation of MeOH as an intermediate step. Another key element in the integration has been the use of a new process for combined synthesis of methanol and dimethylether instead of conventional methanol synthesis. Two versions of the Tigas process schemes have been demonstrated. One version is based on a CO-rich synthesis gas derived from coal gasification with Texaco-type gasifiers, whereas the other version operates on a synthesis gas, produced by Lurgi-type gasifiers or by steam reforming of natural gas.
