International Classification:

C10K 3/02

US Classification:

48111, 48209

Abstract:

The present disclosure relates generally to novel biomass pyrolysis processes and systems that decrease entrainment of char and other contaminants with the pyrolysis vapors. In certain embodiments, the present disclosure provides methods and systems to prevent entrainment of particles of char and heat carrier with pyrolysis vapors leaving a reactor, while allowing rapid upgrading of the vapors by catalyst(s) that are held in a an upgrading reactor and protected from contact with the char.

International Classification:

C01B 32/05
H01M 4/587
C10G 29/02

Abstract:

Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. More specifically, embodiments relate to methods for preparing hard carbon materials used as anode materials in metal-ion batteries, such as a sodium-ion battery. In one or more embodiments, a method includes exposing a liquid refinery hydrocarbon product to a first functionalization agent containing sulfur to produce a first solid functionalized product containing sulfur during a first functionalization process. The method further includes purifying the first solid functionalized product during a purification process and exposing the first solid functionalized product to a second functionalization agent containing oxygen to produce a second solid functionalized product containing sulfur and oxygen during a second functionalization process. The method also includes carbonizing the second solid functionalized product to produce a hard carbon product during a carbonization process.

Abstract:

Embodiments of the present disclosure generally relate to methods for preparing carbon materials which can be used in battery electrodes. In one or more embodiments, a method for preparing an anode carbon material is provided and includes combining a liquid refinery hydrocarbon product and a solvent to produce a first mixture, combining the first mixture and a first oxidizing agent containing an acid to produce a second mixture containing the liquid refinery hydrocarbon product, the solvent, and the first oxidizing agent, and heating the second mixture to produce a reaction mixture containing an oxidized solid product during an oxidation process. The method also includes separating the oxidized solid product from the reaction mixture during a separation process and carbonizing the oxidized solid product to produce a hard carbon product during a carbonization process.

Abstract:

Embodiments of the present disclosure generally relate to carbon materials for battery electrodes and methods for preparing such carbon materials. More specifically, embodiments relate to methods for coating a carbon film onto nano-ordered carbon particles to produce carbon-coated particles which can be used as an anode material within a battery, such as a lithium-ion battery, a sodium-ion battery, other types of batteries. In one or more embodiments, a method for producing carbon-coated particles is provided and includes positioning nano-ordered carbon particles within a processing region of a processing chamber, purging the processing region containing the nano-ordered carbon particles with an inert gas, heating the nano-ordered carbon particles to a temperature of about 700 C. or greater during an annealing process, and depositing a carbon film on the nano-ordered carbon particles to produce carbon-coated particles during a vapor deposition process.

Abstract:

The present disclosure relates to processes and systems that convert biomass to stable intermediate hydrocarbon products that having a greatly decreased oxygen content. This stabilized intermediate hydrocarbon product may be easily be stored for an extended period of time, further refined into liquid transportation fuels (either alone or mixed with petroleum-derived hydrocarbons), or blended with petroleum-derived blendstocks to produce a finished liquid transportation fuel.
