Processes and apparatus are described for removing impurities from solid biomass while preserving hydrogen and carbon content. Examples are provided of processes using acidified aqueous solutions in a countercurrent extraction process that includes the pneumatic transport of slurries between process units, or a mechanical dewatering step, or both, to produce a washed biomass suitable for various upgrading and conversion processes. Compositions related to the processes are also described.

Process and apparatus for removing impurities from solid biomass feeds

The invention comprises methods of catalytically pyrolyzing plastics. Since it has been discovered that plastics provide insufficient coke to provide adequate heat during catalyst regeneration, heat-forming additives can be introduced into the methods. Systems and compositions useful in the catalytic pyrolysis of plastics are also described.

Olefin and aromatics production by the catalytic pyrolysis of polymers

The present invention provides an improved catalytic fast pyrolysis process for increased yield of useful and desirable products. In particular, the process comprises an improved catalytic fast pyrolysis process for producing aromatic compounds, such as, for example, benzene, toluene and xylenes, from biomass feedstock containing impurities, such as, for example alkali and alkaline earth metal, sulfur and nitrogen components.

Catalytic fast pyrolysis process with impurity removal

The present invention provides a catalytic fast pyrolysis process for the production of fuel blendstocks and chemicals. In addition, the invention provides compositions of renewable blendstocks, compositions of renewable fuel blends, and compositions of 100 percent renewable fuels compatible with gasoline specifications and regulations.

Chemicals and fuel blendstocks by a catalytic fast pyrolysis process

The present invention provides an improved catalytic fast pyrolysis process for increased yield of useful and desirable products, while greatly reducing or eliminating fouling of various critical process lines which are likely to transfer heavy hydrocarbons, aromatics and oxygenates. The process comprises steps including feeding a fluid solvent stream having a Snyder Polarity Index of at least 2.4 to one or more of i) the raw fluid product stream from a catalytic fast pyrolysis process fluidized bed reactor to a first separation system, ii) the fluid product stream from the first separation system to a quench vapor/liquid separation system, iii) the vapor phase stream from the quench vapor/liquid separation system to a product recovery system, and, optionally, to the spent catalyst steam stripping system upstream of the catalyst regeneration system.

Catalytic fast pyrolysis process

The present invention provides an improved process for recovering CO from a catalytic fast pyrolysis (CFP) process product effluent. The process comprises the steps of: a) providing a first vapor phase stream resulting from a CFP process comprising, on a water-free and solids-free basis, from 25 to 80% CO and at least 15% CO, b) mixing the first vapor phase stream of step a) with a particular solvent to make a mixed phase stream, c) separating the mixed phase stream of step b) into a second vapor phase stream comprising CO and a liquid phase stream, and d) recovering a product stream from the second vapor phase stream of step c) having a higher concentration of CO and a lower concentration of COthan the first vapor phase stream of step a).
