Pyrolysis oil and method and system for the production thereof
A method for producing a pyrolysis oil is described. In said method, a feedstock to be treated is first pyrolyzed in a pyrolysis zone, in which the feedstock is heated to a temperature of 250 degrees Celsius to 700 degrees Celsius; and pyrolyzed solids and pyrolysis vapors are formed. The pyrolysis vapors are then reformed at a temperature of 450 degrees Celsius to 1,200 degrees Celsius in a post-conditioning zone, in which the pyrolysis vapors are brought into contact with a catalyst bed, wherein the pyrolysis oil is formed. In this case, the catalyst comprises a pyrolyzed solid, which can be obtained according to the pyrolysis, described above. Finally the pyrolysis oil is separated from the additional pyrolysis products, which are formed, in a separation unit.
Process for producing high quality bio-oil in high yield
A process is disclosed for converting a particulate solid biomass material to a high quality bio-oil in high yield. The process comprises a pretreatment step and a pyrolysis step. The pretreatment comprises a step of at least partially demineralizing the solid biomass, and improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass. In a preferred embodiment the liquid pyrolysis product is separated into the bio-oil and an aqueous phase, and the aqueous phase is used as a solvent in the demineralization step and/or in the step of improving the accessibility of the solid biomass by opening the texture of the particles of the solid biomass.

Apparatuses and methods for controlling heat for rapid thermal processing of carbonaceous material
Embodiments of apparatuses and methods for controlling heat for rapid thermal processing of carbonaceous material are provided herein. The apparatus comprises a reheater for containing a fluidized bubbling bed comprising an oxygen-containing gas, inorganic heat carrier particles, and char and for burning the char into ash to form heated inorganic particles. An inorganic particle cooler is in fluid communication with the reheater to receive a first portion of the heated inorganic particles. The inorganic particle cooler is configured to receive a cooling medium for indirect heat exchange with the first portion of the heated inorganic particles to form first partially-cooled heated inorganic particles that are fluidly communicated to the reheater and combined with a second portion of the heated inorganic particles to form second partially-cooled heated inorganic particles. A reactor is in fluid communication with the reheater to receive the second partially-cooled heated inorganic particles.
Demetallization of liquid biomass
Methods, processes, systems, or apparatus are provided to remove contaminants such as metals and chlorine present in a pyrolysis stream to form reduced-contaminant liquid biomass. In certain embodiments, for example, a metal chelating agent is dissolved into a metal-containing pyrolysis stream condensate to form metal chelate complex, followed by filtering to obtain the reduced-contaminant liquid biomass.
Process for producing bio-products from biomass using rotary compression unit
A bio-product such as biochar, bio-coal, bio-oil, coke, and/or activated carbon material is formed by processing a starting biomass material comprising water-laden material. The starting biomass material is heated to below or above an autoignition temperature through a rotary compression unit (RCU) by generating steam through releasing unbound and bound waters in the biomass thus forming a bio-product. The biomass material being processed may be, without limitation, a woody or non-woody biomass material, such as cellulosic material and/or grain. The process can also form bio-oil from pyrolysis vapors which can be processed to other bio-products.
