Abstract: Slurry bubble columns equipped with downcomers which have high efficiency gas disengagement means fitted on top of the slurry liquid reaction mixture comprising an inverted channel having a gas vent extending out of the apex of the inverted channel and a liquid by-pass pipe extending from the side of the inverted channel at a point below the apex to under the liquid level and emptying into the downcomer. The inverted channel is fitted to the top of said downcomer and the bottom edge of which inverted channel is in contact with the surface of the slurry mixture in the slurry bubble column reaction zone. Improved catalyst distribution and circulation, mass and heat transfer results from catalyst in gas-lean slurry flowing through the liquid by-pass tubes in the inverted channel and flowing into and down the downcomer to the bottom of the bubble column reactor.

Abstract: Accumulation of carbonaceous deposits on the combustion chamber surfaces of internal combustion engines is responsible for increased fuel octane requirement to prevent knock. Treatment of these carbonaceous deposits with weak bases, such as aqueous ethylenediamine, aids in their removal and thereby reduces the octane requirement of an internal combustion engine. The method is also applicable for removal of carbonaceous deposits from metal surfaces generally.

Abstract: A process for recovering oil from tar sands by subjecting the tar sands to aqueous extraction to produce a bitumen-rich layer containing bitumen, water and solids and a bitumen-lean layer containing relatively less bitumen and relatively more water and solids. The solids present in the bitumen-lean layer contain a substantial portion of finely divided clay having adhered organic matter. The clay solids are retained with the bitumen from the bitumen-lean layer and the bitumen-clay mixture is pyrolyzed. Pyrolysis of the bitumen-lean layer containing clay having adhered organic matter reduces the volume of aqueous tailings which would otherwise be produced and also results in increased hydrocarbon yields.
