Process to prepare a char product and a syngas mixture
The invention is directed to a process to prepare a char product and a syngas mixture comprising hydrogen and carbon monoxide from a solid torrefied biomass feed comprising the following steps: (i) subjecting the solid biomass feed to a pyrolysis reaction thereby obtaining a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds and a solid fraction comprising of char particles; (ii) separating the char particles as the char product from the gaseous fraction; (iii) subjecting the gaseous fraction obtained in step (ii) to a continuously operated partial oxidation to obtain a syngas mixture further comprising water and having an elevated temperature and (iv) contacting the syngas mixture with a carbonaceous compound to chemically quench the syngas mixture. The temperature of the syngas is reduced in step (iv) from between 1000 and 1600° C. to a temperature of between 800 and 1200° C.

Covered cavity kiln pyrolyzer
The invention presents a covered cavity kiln pyrolyzer with modulated means of rotation, to promote mixing and exposure of the biomass to heat, thereby allowing complete and efficient pyrolysis of biomass therein. The invention has a portal arrangement for simultaneous entry of fuel and air alongside the exit of emissions and flames to a separate hood structure. In addition to rotational modulation for mixing, the rotational capabilities of the kiln also permit the removal of processed charcoal when the portal is turned downward. The invention also has a system of internal prongs for mixing and sifting removal of char, as well as automated fuel delivery mechanisms and a system of openings to allow insertion of pipes and sensors into the kiln for monitoring and for additional delivery of reagents for better modulation and efficiency by a user during the pyrolyzation process.
PROCESS TO PREPARE A CHAR PRODUCT
The invention is directed to a process to prepare a char product by pyrolysis or mild gasification of a solid biomass feed thereby obtaining a gaseous fraction comprising hydrogen, carbon monoxide and a mixture of gaseous organic compounds and a solid fraction comprising of char particles having a reduced atomic hydrogen over carbon ratio and a reduced oxygen over carbon ratio relative to the solid biomass feed. The solid biomass feed are pellets of a solid torrefied biomass feed. The pyrolysis or mild gasification is performed at a temperature of between 500 and 800° C. and at a solid residence time of between 10 and 60 minutes.
Pyrolysis process and products
A pyrolysis device and process to convert a carbonaceous feedstock to a carbon solid and pyrolysis gas, and processes for refining the resulting carbon solid and pyrolysis gases. The pyrolysis process may include introducing a carbonaceous feedstock into a pyrolysis processor having a vertical rotary tray processor, heating the feedstock to a temperature above about 790° F., removing a carbon material from a bottom of the pyrolysis processor, and removing a pyrolysis gas from a top of the pyrolysis processor.

Reactor for drying and torrefying a biomass, preferably a lignocellulose biomass
A reactor for drying and torrefaction, configured for torrefying biomass, including a chamber in which two separate areas are delimited, a mechanism for mixing and transferring biomass from one end of the chamber to the other, a drying device in an upstream area of the chamber configured to dry the biomass introduced into the reactor, a torrefaction device in a downstream area of the chamber configured to torrefy biomass dried in the upstream area, and a transfer and sealing system configured to allow dried biomass to be transferred from the upstream area to the downstream area at time intervals, and to make the two areas mutually sealed during each interval. Such a reactor may, for example, find application to torrefaction of lignocellulosic biomass.

Apparatus and method for conversion of solid waste into synthetic oil, gas, and fertilizer
A method of producing oil, gas, and ash fertilizer from a feedstock includes inputting the feedstock into a reaction chamber having a wall, and combusting the feedstock in the reaction chamber. An electrical current flow is induced between the reaction chamber wall and the feedstock so as to cause arcing in the feedstock within the reaction chamber. Ash reaction byproducts migrate downward through the reaction chamber onto ash support structure, which is substantially electrically isolated from the reaction chamber wall. Gas and liquid reaction byproducts migrate upward through the reaction chamber to an upper chamber by a partial vacuum in the upper chamber, and are evacuated therefrom. The oil and gas are then separated from the evacuated gas/liquid products, providing the oil and the gas products. The oil is refinable, the gas is high in energy content, and the ash fertilizer is high in nitrogen.
