摘要： The present invention is an improved process for the recovery of bitumen from tar sand by employing a vessel containing a liquid comprising an organic phase consisting of a hydrocarbon solvent which is immiscible in water and an aqueous phase. The tar sand optionally containing water is introduced into the organic phase and then subsequently passes into the aqueous phase.

摘要： Waste water produced in an acrylonitrile plant and containing significant amounts of acrylonitrile and acrylic acid is processed so as to reduce its organics content for disposal purposes and to recover the acrylonitrile and acrylic acid contained therein. The waste water is treated by contact with activated carbon to adsorb the organics contained therein. The activated carbon is periodicaly regenerated with a desorbing liquid and the desorbate product is distilled to yield acrylonitrile and acrylic acid. Every fifth regeneration cycle, the activated carbon is regenerated thermally rather than means of a liquid in order to restore its activity to its original value.

摘要： An improved process for the production in high yield of activated carbon particles of high activity comprises rapid removal of volatile material from the area of carbonaceous particles during the carbonization step by individually venting each hearth of a multiple hearth furnace. The carbonaceous particles which are subjected to the carbonization step are prepared from mixtures of carbonaceous material and petroleum acid sludge.
