Recovering liquid and gaseous hydrocarbons from solid raw materials containing hydrocarbons such as oil shale or coal by treating with a solvent oil at a temperature of 610.degree. K.-690.degree. K. and under pressure in the presence of hydrogen. The oil solvent is introduced into a heated vessel in vapor form. The raw material is introduced into the heated reaction vessel at a temperature below the condensation temperature of the oil to cause the oil vapor to condense at the surface of the raw material. The reaction vessel is heated to cause the raw material leaving the reaction vessel to be at a temperature above the condensation temperature of the oil at the pressure prevailing in the reaction vessel.

In a gas generation method in which liquid fuel is catalytically reacted with air at elevated temperatures to form a fuel gas, several plates each having a multiplicity of passage openings are arranged in tandem in spaced fashion within the reaction chamber of the gas generator and are embedded in a bed of packing material with the thermal conductivity of the plates higher than that of the packing material in order to obtain more uniform heating of the reaction chamber and better mixing and distribution of the reacting media permitting the gas generator to be loaded more heavily.

System for recovering oil products from oil sands in which superheated steam from a nuclear reactor is mixed with water in a chamber under high superatmospheric pressure to obtain hot water at a temperature near the boiling point at the prevailing pressure. The hot water enters a reaction tube which has an input screw conveyor for feeding oil sands into the reaction tube in contact with the hot water to effect release of the oil from the sands. The outlet of the reaction tube opens into a hydrocyclone into which the reaction products of oil and sand and water are discharged. A screw conveyor at the bottom of the hydrocyclone discharges separated sand and some water which passes into a settling tank to settle the sand and the clarified water is filtered and returned to the pressure chamber. The separated oil together with some water from the hydrocyclone flows to an oil separator where the oil separates from the water, which latter is also returned to the pressure chamber. The oil may be separated into fractions in a fractionating column and the column bottoms may be hydrogenated and returned to the fractionating column. Better oil recovery from the oil sand can be achieved and more efficient operation attained.

According to the invention, the fuel is supplied to the reformed-gas generator in an amount at least approximately proportional to the instantaneous demand of the internal-combustion engine and is mixed there, in atomized or evaporated form, with so much air and/or fed-back exhaust gas drawn in through the reformed-gas generator that for the air component of the mixture, the air number for the reaction of the fuel in the converter is at least 0.05 but not more than 0.5 and the exhaust gas component does not fall below the exhaust gas quantity equivalent to the air number 0.05 and does not exceed the exhaust gas quantity equivalent to the air number 0.5. The fuel gas mixture produced in this manner, prior to being fed to the combustion chambers of the internal-combustion engine, is mixed with enough additional air sucked in by the internal-combustion engine such that the air number for the combustion in these combustion chambers is at least equal to 1.

The invention concerns a column for bringing gases or vapors and liquids into contact which uses a plurality of plates made from a highly porous, open-pore, sintered material. According to the invention, the gas and the liquid are conducted in this column countercurrent-wise; the column plates are equipped with run-off tubes which have at the lower end a gas shut-off device such that upon starting, the path for the gas is blocked by the gas shut-off device because of the liquid column contained therein. This liquid column exerts on the gas a larger pressure than corresponds to the pressure difference between the gas in the space under the associated column plate and that above. The run-off tube is of such size that it is only partly filled by the liquid column so that it can continuously adjust itself during operation. The actual reaction between the gas and the liquid takes place partially within the column plates resulting in a greater exchange between the liquid and the gas and making the column relatively insensitive to motion effects and load variations.

Apparatus for bringing gases and liquids into contact

The invention concerns a device for quick starting a reformed gas converter. A first fuel nozzle vaporizes fuel supplied thereto and directs the fuel towards a flame tray. An oxygen carrying gas is combined with the vaporized fuel and the mixture is ignited by a suitable ignition device. The hot gases generated permeate through the device to pre-heat a catalytic converting material such as a perforated sintered block. A second fuel nozzle, after the converting material has been pre-heated to a minimum temperature, directs a stream of vaporized liquid fuel against the heated block. The reform gas generated passes into the reform gas generator proper as fuel therefor. By control of the combustion temperature, the hot gases generated by the ignition step when they pass through the sintered block will also be partially converted to reform gas, suitable for fuel for the generator proper, thereby allowing immediate operation of the generator.
