Biomass injection into fluid bed catalytic pyrolysis reactor
An improved process is provided for catalytic pyrolysis of biomass, comprising pneumatically injecting a biomass feed via a pneumatic injection line into a fluidized heat medium, for example, hot catalyst, with a carrier gas at a velocity of from 5 to 40 m/s in at least one mixing zone in communication with a pyrolysis reactor in which catalytic pyrolysis occurs, and maintaining a catalyst/biomass mixture flowrate ratio (C/B) of from 4 to 40 downstream from the point of catalyst injection via a catalyst injection line in the at least one mixing zone.

Fluidized Bed Plastic Waste Pyrolysis With Melt Extruder
Systems and methods are provided for conversion of polymers (such as plastic waste) to olefins. The systems and methods can include an initial pyrolysis stage where a plastic feedstock is delivered to the initial pyrolysis stage by one or more melt extruders. The one or more melt extruders can be heated to maintain the plastic feedstock in a liquid state during delivery of the plastic feedstock to the initial pyrolysis stage. This can allow for delivery of the plastic feedstock into the pyrolysis process with a controlled distribution of plastic into the pyrolysis reactor.

CHEMICAL RECYCLING OF PLASTIC-DERIVED STREAMS TO A CRACKER SEPARATION ZONE
Methods and systems are provided for the conversion of waste plastics into various useful downstream recycle-content products. More particularly, the present system and method involves integrating a pyrolysis facility with a cracker facility by introducing at least a stream of r-pyrolysis gas into the cracker facility. In the cracker facility, the r-pyrolysis gas may be separated to form one or more recycle content products, and can enhance the operation of the facility.
INTEGRATED PYROLYSIS AND GASIFICATION OF BIOMASS
Systems and methods are provided for integrated pyrolysis and gasification of a biomass feed, either as a separate feed or under co-processing conditions. The integrated pyrolysis and gasification can be performed using any convenient reactor configuration, such as fluidized coking reactor configuration or a fluid catalytic cracking reactor configuration. The biomass feed can initially by pyrolyzed to form liquid products, gas phase products, and char. The char can then be used as the input feed to gasification. In aspects where the biomass feed is co-processed, the biomass can be co-processed with a co-feed that is suitable for processing under fluidized coking conditions or other pyrolysis conditions, such as a conventional fluidized coking feedstock.
