摘要:
A method that combines the oil retorting process (or other process needed to obtain/extract heavy oil or bitumen) with the process for upgrading these materials using sodium or other alkali metals. Specifically, the shale gas or other gases that are obtained from the retorting/extraction process may be introduced into the upgrading reactor and used to upgrade the oil feedstock. Also, the solid materials obtained from the reactor may be used as a fuel source, thereby providing the heat necessary for the retorting/extraction process. Other forms of integration are also disclosed.

The invention provides for torrefaction apparatus which includes a drum (14) having a biomass inlet (18) and a torrefied material outlet (20), furnace means (16) external of the drum (14) for heating the drum (14) so that torrefaction temperature is achieved in the drum, and a gas inlet conduit (42) leading to the drum (14) from a source of inert gas, thereby to create an torrefaction atmosphere in the drum (14).
摘要:
In a first condensation stage (which is on the rising current end of the low-temperature carbonization drum and the equipment for which is integrated) quenching is done with a cooled low-temperature carbonization oil fraction containing solids. Simultaneously the whole discharge opening placed on the rising current end in the base region of the low-temperature carbonization drum for the volatile components of the low-temperature carbonization process is continuously scrubbed clean with the low-temperature carbonization oil fraction containing solids. Additionally, the volatile and liquid components are also drawn off simultaneously.

This invention relates to a method for thermal utilization of solid organic household and industrial waste, and may be applied in municipal economy, chemical, petrochemical and other branches of industry for the regeneration of hydrocarbons into fuel oil and fuel gas. The dephlegmatic phased method of organic waste utilization, comprising multistage pyrolysis of waste in a reactor without air access, at temperature not more than 1000° with obtaining of solid carbon residue and multi-component gas-vapor mixture, cooling of gas-vapor mixture in multiloop circulatory cooling system, extraction of a heavy fraction for repyrolysis and obtaining of a liquid fraction having indicated molecular mass and gas on a finite circuit. Organic waste are exposed stepwise to the pyrolysis with reloading of non-decomposed solid residue from a retort of the first stage reactor having temperature 150-180° C., sequentially to retorts for the pyrolysis at higher temperatures, and gas-vapor mixture from the retorts is directed to not less than one dephlegmator, there it is purified from tar composition, and tar composition being returned to a retort for the re-pyrolysis, gas-vapor mixture from the dephlegmator being conveyed to a fraction distributor for cooling, and combustion gases from a casing of the last retort being conveyed to casings of the preceding retorts, and then jointly with combustion gases generated by heaters under the casings of all retorts are delivered outside. The attained object is the provision of an apparatus for the pyrolysis of improved effectiveness, obviating overheating and reheating of the finished product, and providing for obtaining of qualitative oil and gas fuel and pyrographite.
摘要:
A NONCATALYTIC MULTI-HYDROTORTING PROCESS FOR MAXIMIZING THE CONVERSION OF COAL INTO COAL OIL. A PUMPABLE COAL-WATER SLURRY IN ADMIXTURE WITH A STREAM OF SYNTHESIS GAS IS PASSED THROUGH A TUBULAR RETORT WHERE IT IS HEATED TO A TEMPERATURE IN THE RANGE OF ABOUT 600 TO 950* F. IN THE ABSENCE OF AIR. THE SOLID COAL PARTICLES ARE FRAMENTIZED AND CARBONIZED IN THE TUBULAR RETORT, THE VOLATILE CONSTITUENTS IN SAID SLURRY ARE VOLATILIZED AND SIMULTANEOUSLY HYDROGENATION OF THE PROCESS STREAM TAKES PLACE. THE EFFLUENT FROM THE TUBULAR RETORT IS THEN INTRODUCED INTO A FLUIDIZED BED RETORT ALONG WITH A SECOND STREAM OF SYNTHESIS GAS. THERMAL DECOMPOSITION OF THE CARBONACEOUS MATERIALS TAKES PLACE IN THE ABSENCE OF AIR AND THE PROCESS STREAM IS HYDROGENATED FOR A SECOND TIME. THE PROCESS STREAM LEAVING THE FLUIDIZED BED RETORT IS COOLED TO CONDENSE OUT AND SEPARATE WATER AND RAW COAL-OIL IN A GAS-LIQUID SEPARATION ZONE. A PORTION OF THE OFF-GAS FROM THE GAS-LIQUID SEPARATOR MAY BE SCRUBBED AND PURIFIED TO PRODUCE NONPOLLUTING FUEL GAS HAVING A HIGH HEATING VALUE. SPENT CARBONACEOUS PARTICLES LEAVING THE FLUIDIZED BED RETORT AND OPTIONALLY A PORTION OF THE OFF-GAS FROM THE GAS-LIQUID SEPARATOR ARE INTRODUCED INTO A FREE-FLOW NONCATALYTIC GAS GENERATOR FOR CONVERSION INTO PREFERABLY HYDROGEN-RICH SYNTHESIS GAS BY PARTIAL OXIDATION FOR USE IN THE AFORESAID TWO HYDROTORTING STAGES.

A process and apparatus for upgrading heavy hydrocarbons such as asphaltenes to lighter oil and gas components is disclosed. The process provides a reaction environment that promotes fast and selective cracking of heavy hydrocarbons, while minimizing coke formation and fouling and enhancing product yields.
