System and Method for Obtaining Clean Coal Tars from Pyrolized Coal and Biomass

Номер: US20120024204A1
Принадлежит: Individual

A system and method for collecting hot coal tar gases emanating from a coal containing pyrolytic kiln are described. The hot coal tar gases, comprising a variety of different hydrocarbons as well as inorganic gases arising from the kiln thermal processing are transferred by diffusion and forced convection to a thermal duct in which the temperature is controlled to be maintained at a temperature below that of the kiln. The gaseous hydrocarbon with the highest condensation temperature is the first to liquefy. Additional useful hydrocarbons liquefy as the temperature of the gas continues to cool from the kiln temperature of ˜5000 C to one approaching the minimum duct temperature, ˜175° C. After a number of desirable hydrocarbons present in the coal tar gas have liquefied, the liquid contents are collected, either separately or as a combination of liquid hydrocarbons. The several remaining inorganic and some hydrocarbons gases with condensation temperatures below the minimum duct temperature are separately collected in gaseous form for further processing and/or safe disposal.

Systems and processes of providing novel thermal energy sources for hydrothermal liquefaction (HTL) reactors are described herein. According to various implementations, the systems and processes use concentrated solar thermal energy from a focused high-energy beam to provide sufficient energy for driving the HTL biomass-to-biocrude process. In addition, other implementations convert biowaste, such as municipal biosolids and grease and food waste, to biocrude using anaerobic digesters, and a portion of the biogas generated by the digesters is used to produce the thermal and/or electrical energy used in the HTL reactor for the biomass-to-biocrude process. Furthermore, alternative implementations may include a hybrid system that uses biogas and solar radiation to provide sufficient thermal energy for the HTL reactor.

THREE STEP ULTRA-COMPACT PLASMA SYSTEM FOR THE HIGH TEMPERATURE TREATMENT OF WASTE ONBOARD SHIPS

Номер: US20190056105A1
Принадлежит: PYROGENESIS CANADA INC.

An apparatus for thermal processing of waste having organic and inorganic components comprises at least a treatment station, a cooling station and a treated material-removal station, and at least three crucibles. The treatment station is adapted to thermally treat the organic components and/or inorganic components located in a given one of the crucibles located at the treatment station. The so-treated components in this given crucible are adapted to then be cooled at the cooling station, before the treated components located in the given crucible are removed therefrom at the treated material-removal station. The three crucibles are mounted on a turntable so that the three crucibles are each at one of the stations, before synchronously all moving to each crucible's next station. 1. An apparatus for thermal processing of waste having organic and inorganic components , comprising: at least a treatment station , a cooling station and a treated material-removal station , at least three crucibles being provided , wherein said treatment station is adapted to thermally treat the organic components and/or inorganic components located in a given one of said crucibles located at said treatment station , treated components in said given crucible being adapted to then be cooled at said cooling station , before the treated components located in said given crucible are removed therefrom at said treated material-removal station.2. The apparatus as defined in claim 1 , wherein said three crucibles are positioned in respective ones of said treatment claim 1 , cooling and treated material-removal stations claim 1 , and are adapted to be cyclically displaced from said treatment station to said cooling station to said treated material-removal station claim 1 , before returning to said treatment station for a new cycle.3. (canceled)4. The apparatus as defined in claim 2 , wherein said crucibles are mounted on a turntable adapted to displace said crucibles from between said stations claim ...
