A process for production and recovery of hydrocarbons from hydrocarbon-containing whole plants in a form suitable for use as chemical feedstocks or as hydrocarbon energy sources which process comprises: (a) pulverizing by grinding or chopping hydrocarbon-containing whole plants selected from the group consisting of Euphorbiaceae, Apocynaceae, Asclepiadaceae, Compositae, Cactaceae and Pinaceae families to a suitable particle size, (b) drying and preheating said particles in a reducing atmosphere under positive pressure (c) passing said particles through a thermal conversion zone containing a reducing atmosphere and with a residence time of 1 second to about 30 minutes at a temperature within the range of from about 200°C. to about 1000°C., (d) separately recovering the condensable vapors as liquids and the noncondensable gases in a condition suitable for use as chemical feedstocks or as hydrocarbon fuels.

A process using whole-plant biomass for production of fuel gases and organic liquids suitable for use as hydrocarbon fuels and as chemical feedstocks which comprises: (a) feeding a ground or chopped whole-plant biomass of a suitable particle size to an autothermic furnace containing a heating and drying zone, a thermal conversion zone and an oxidation zone wherein said furnace is a moving bed furnace and means are provided for exclusion of oxygen-containing gases from the inlet port, (b) heating and drying said biomass with reducing gases at a temperature within the range of from about 100°C. to 700°C., (c) removing said biomass from said heating and drying zone to said thermal conversion zone wherein a reducing atmosphere is present at a temperature of 200°C. to 1000°C., (d) exposing said biomass in thermal conversion zone to said temperature for a period of 1 second to 30 minutes, (e) removing said biomass from thermal conversion zone to oxidation zone wherein said biomass is partially oxidized to char at a temperature of 500°C. to 1000°C. in the presence of oxygen-containing gases selected from the group consisting of molecular oxygen and air, (f) removing said biomass from said oxidation zone wherein means are provided for exclusion of oxygen-containing gases from the outlet port, (g) removing product gases from heat and drying zone, (h) recovering liquid condensables from product gases.
