FEED NOZZLE ASSEMBLY FOR A CATALYTIC CRACKING REACTOR

摘要

Reactor vessel and a feed nozzle assembly (1) for feeding a gas and a liquid into such reactor vessel. The feed nozzle assembly comprises an outer tube (3) supplying a first liquid feed, such as oil, an inner tube (2) supplying a dispersion gas, such as steam, a third tube (23) supplying a second liquid feed, such as biomass, and a nozzle end. A catalytic cracking process wherein two or more hydrocarbon liquids are jointly dispersed into a dispersion gas and jetted via the same feed nozzle assembly (1) into a catalytic cracking reactor (30).
