ABSTRACT:
Solid hydrocarbon-containing material, such as oil shale, coal or tar sand, is fed into a retort through a multiplicity of feed lines to enhance retorting efficiency, throughput and product yield. In the preferred form, larger particles of hydrocarbon-containing material gravitate downwardly through the retort in countercurrent relationship to an upward fluidized stream of smaller particles of hydrocarbon-containing material. This arrangement is especially useful to retort larger particles of hydrocarbon-containing material. One or more streams of intermediate size particles of hydrocarbon-containing material can also be fed into the retort.
