Abstract
Hybrid catalysts composed of a specially designed methanol synthesis catalyst and solid acids could make butane-rich paraffin mixture from synthesis gas containing CO_2, at below 300℃ and under 2-3 MPa. The catalyst could make similar hydrocarbon mixture from only CO_2 and H_2. The product contained little dry gas (C_1-C_2) and C_6+ paraffins. The catalyst could be used more than 5,000 hr without regeneration and the deactivated catalyst was regenerated in situ. The combination of this process with the well designed gasification process gave the energy recovery of about 40% or higher, from woody biomass.
