Method of extracting oil and by-products from oil shale

摘要: Oil and by-products are extracted from oil shale by drilling a hole into the bed heating in its bed. Steam oxygen or air mixtures provide self-sustaining that draws form of vapor mist. As is removed, heat subsequent water gas reaction changes hard whitish, weak structured, friable material. This material falls, own weight, to bottom hole, thus exposing new for processing. Action steam with residual carbon generates hydrogen nd adds flow carries mist surface, together ash particles. The oil, any other valuable materials, separated before it either converted building block dumped used cavity.
