Dason Technology developed a short contact time catalytic partial oxidation (SCOR) technology. With the SCOR technology, the following catalytic reactions are carried out in one reactor vessel at very short residence time (~ms):
CH4 + 0.5O2 = CO + 2H2
Dason’s SCOR reactor operates under moderate temperature and pressures, and has low cost to fabricate and operate. >90% C-atomic conversion efficiency was demonstrated for conversion of natural gas to syngas.
Molecule Works Inc. invented a compact monolith reactor technology for conversion of syngas to liquid hydrocarbons. The monolith reactor is packaged with monolithic catalyst blocks comprising a number of small, straight flow channels with active catalysts as the channel wall. The monolith structure substantially enhances gas/liquid/catalyst contacting efficiency and mass transfer rates, and provides 3-dimensional, continuous solid matrix for thermal conduction. Greater than 90% one-pass syngas conversion is achieved in a 20-cm long monolith reactor tube at <10% selectivity to methane. The monolith reactor allows the syngas conversion be conducted effectively at relatively low pressures (~10bar) and tolerates presence of CO2 and N2.
Combination of those two new reactor technologies significantly simplifies separation, reaction, and heat transfer process steps, and makes it possible to develop a compact GTL plant.
