ABSTRACT:
A blast furnace is employed to process a natural material selected from the group consisting of oil shale, oil sandstone, asphalt rock or mixtures thereof. A first carbonaceous material selected from the group consisting of oil shale, oil sandstone, asphalt rock or mixtures thereof and a second carbonaceous material are charged to the top of a blast furnace and the carbonaceous char material remaining when the burden reaches the lower portion of the blast furnace in front of the primary tuyeres is burned to provide a hot, upwardly-moving gas stream containing CO and H.sub.2 to vaporize recoverable hydrocarbons contained in the carbonaceous material as the carbonaceous material moves downwardly through the blast furnace. A gas containing hydrocarbons, CO, H.sub.2 and vaporized carbonaceous oil and tar is withdrawn from near the top of the blast furnace and a molten slag is withdrawn from near the bottom of the blast furnace. The off gas can be condensed to provide liquid oils and a gas having a desirable Btu content. Provision is also disclosed for the removal of alkali metals from the process.
