Abstract
Processes and apparatuses for co-processing pyrolysis effluent and a hydrocarbon stream in which a char produced by the catalytic cracking of the pyrolysis effluent is recovered and utilized to provide energy, such as heat to the catalytic cracking zone. The char can be burned in various combustion zones associated with the catalytic cracking zone. The char is produced from a renewable resource.
Claims14
A process for recovering energy in a fluid catalytic cracking zone, the process comprising:
- generating char in a fluid catalytic cracking zone, the fluid catalytic cracking zone configured to receive at least a hydrocarbon stream and a pyrolyzed product and provide a cracked effluent, wherein the cracked effluent includes char;
- separating the char from hydrocarbons in the cracked effluent to provide a recovered char;
- and
- recovering energy from the recovered char.
