摘要:
A system is provided that enables a continuous process that involves the introduction of particles into a reactor drum having a low oxygen environment. Heavy hydrocarbons are boiled off of the particles during the heating of the particles. The boiled off heavy hydrocarbons mix with a heated gas stream that heats the particles within the reactor drum. The heated gas stream (with the boiled off heavy hydrocarbons) exit the drum and are recirculated back to a heat source for reheating the gas stream prior to reentering the reactor drum. Repeated exposure to the elevated temperatures within the reactor drum cracks the heavy hydrocarbons into lighter hydrocarbons. The lighter hydrocarbons may then be separated out of the heated gas stream and collected for sale or use.

A high-temperature retort structure enclosing an inner retort volume. The high-temperature retort structure includes a floor forming a lower boundary of the inner volume, a ceiling forming an upper boundary of the inner volume, and a wall forming a lateral boundary of the inner volume. The floor has at least one discharge opening for discharging of material, and the ceiling has at least one intake opening for intake of material. The wall is comprised of an inner layer of high-temperature resistant, fast curing material, an intermediate layer of high-temperature concrete, and a permeability barrier disposed external to the intermediate layer.

Apparatus is disclosed herein for reducing engine nitrogen oxide emissions by mixing hydrogen prepared from a portion or all of engine fuel within a simple burner. The apparatus includes an insulated burner having an internal combustion chamber for receiving either a portion of or all the gaseous fuel or liquid fuel for mixture with air and subsequent ignition by a spark plug. The chamber is within a feed preheater assembly. A mixing chamber is included having a series of baffles against which injected air and fuel vapor impinge causing thorough and complete air/fuel blending into a mixture subsequently ignited and burned, and then discharged into the combustion chamber of the engine itself. The pre-heating assembly raises the temperature of the incoming air/fuel mixture via a heat exchanging process with post combusted gases from the combustion chamber. The apparatus improves operability and performs by conserving energy by insulating the total burner, placing the burner section within the feed preheater assembly, and locating the feed mixture flow of the preheater adjacent to the outer insulation; and hydrogen output may be increased by reaction between carbon monoxide and water produced by the main reaction or added separately.

THE PRESENT INVENTION CONCERNS A METHOD AND APPARATUS FOR TREATING A HYDROCARBONACEOUS PROCESS FLUID BY INDIRECTLY HEATING SUCH FLUID TO HIGH TEMPERTURES IN EXTREMELY SHORT PERIODS OF TIME AND THEN RAPIDLY COOLING. THE PROCESS FLUID IS PASSED INTO THE STRAIGHT SINGLE PASS REACTION TUBES OF THE NOVEL HEATER OF THIS INVENTION, SUCH REACTION TUBES BEING CONTAINED IN A REFRACTORY ENCLOSURE. THE TUBES ARE EACH CONNECTED TO AN INDIVIDUAL QUENCH TUBE WHEREIN THE PROCESS FLUID MAY BE RAPIDLY COOLED EITHER BY A COOLANT FLOWING THROUGH A PLURALITY OF JACKETS
EACH SURROUNDING EACH INDIVIDUAL QUENCH TUBE OR, IN ANOTHER EMBODIMENT, THE PROCESS FLUID MAY BE COOLED BY HAVNG THE QUENCH TUBES IMMERSED IN A LIQUID BATH. IN ANOTHER EMBODIMENT OF THIS INVENTION A METHOD AND APPARATUS IS PROVIDED FOR CARRYING OUT THE AFOREMENTIONED METHOD WHILE SIMULTANEOUSLY DECOKING INDIVIDUAL REACTION TUBES.
摘要:
Methods and system for obtaining long chain carbons that generally include forming a conversion mixture of an alcohol and a base, adding the conversion mixture to oil (such as petroleum based oil, crude oil, used oil, used motor oil, and new motor oil) to form a reaction mixture, adding a high nitrate compound the reaction mixture, and separating out the long chain carbons for use as an input by other processing such as pharmaceutical and/or additional petro-chemical processing. Additional cooling and/or filtering processes may be utilized to complete and/or optimize oil conversion.

A process for refining raw materials containing oil and/or bitumen includes supplying the raw materials to a reactor. The reactor is operated under a pressure of from 0.001 to 1 bar and at a reactor temperature of from 300 to 1000° C. so as to volatize fuel gases and obtain solids and non-evaporated fractions of heavy hydrocarbons. The solids and non-evaporated fractions of heavy hydrocarbons are introduced into a furnace. The non-evaporated fractions of heavy hydrocarbons are burned in the furnace at a furnace temperature of from 600 to 1500° C. so as to obtain hot solids in the furnace. The hot solids are recirculated from the furnace into the reactor. An oxidizing atmosphere of the furnace is separated from an atmosphere of the reactor by a sealing device.

The present invention relates to a device for heating a cylindrical component of given diameter, by means of hot gas, characterized in that it comprises at least two heaters (310, 312, 314) each delivering a stream of hot gas and emerging in an annular chamber (316), the inside diameter of which is slightly greater than said diameter. This device is used in particular for heating a metal journal (111) in which a bearing ring (123) for an inter-shaft bearing in a double-body turbomachine is mounted.

A self-sustaining system for converting organic waste feedstreams into usable solid and gas end products includes a plurality of interconnected retorts, an apparatus for flash pyrolyzing the feedstream to form intermediate gas and solid products, a source for introducing a water spray to refine and cool the intermediate products, a device for separating the gas product from the solid product and a device for regenerating, and thereby further refining, the solid product. In a self-sustaining process, wastes which would otherwise be landfilled are converted to an activated carbon product and a combustible gas mixture of hydrogen, carbon monoxide, and lower hydrocarbons.
