Patent
·
OSTI ID:7234061
This patent describes a process for liquefying a carbonaceous solid in a thermal liquefaction heater in a first stage thermal liquefaction in the presence of a liquefaction solvent, followed by a second stage catalytic hydrogenation wherein liquefaction solvent is recovered from the second stage for use in the first stage. This patent describes improvement in introducing a liquefaction solvent to the first stage liquefaction heater.
