© SCF TECHNOLOGIES A/S26 MARCH 20108CatLiq ® Conversion Process: Key features• The organic solids are liquefied, oxygen removed and moleculessplit and rearranged, resulting in a liquid fuel with high energy density• The catalytic process operates at near-critical conditions of water atapprox. 350 0 C and 250 bars (conditions common to the oil industry)- strong sterilisation effect• The residence time in the reactionzone is relatively short (approx. 30 min.)- small process footprint• The plant may be manufactured inmodules
