A two-step process that includes a pyrolytic first step carried out in a mechanically or gravitationally impelled reactor and a catalytic fluid bed second step that upgrades the resulting vapor, for the conversion of waste plastics, polymers, and other waste materials to useful chemical and fuel products such as paraffins, olefins, and aromatics such as BTX is described.

Two step process for chemically recycling plastic waste

Methods and systems utilizing gas jets to carry biomass into a biomass conversion reactor are described. Reactor configurations and conditions for carrying out processes utilizing the gas jets are also described. The use of gas jets has been found to be especially desirable for operation with pyrolysis of biomass in catalytic fluidized bed reactors.

Gas jet injector reactor for 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.
