Fluidized bed reactor system

摘要

A fluidized-bed reactor system with at least two fluidized-bed reactors, each being a circulating fluidized bed, a particle line with a particle separator for transferring fluidized-bed particles from the first to the second reactor, and a particle line exiting at the lower half of the second reactor for transferring fluidized-bed particles back to the first reactor, wherein, at least in the second reactor, two or more reaction zones separated by one or more flow controllers and that the particle line opens into the second reactor above at least one flow controller.

1. A fluidized-bed reactor system, comprising:
a first circulating fluidized-bed reactor; a second circulating fluidized-bed reactor; a first particle line comprising a particle separator configured to transfer fluidized-bed particles from the first to the second reactor; and a second particle line exiting at a lower half of the second reactor, configured to transfer fluidized-bed particles back to the first reactor, wherein at least the second fluidized-bed reactor comprises two or more reaction zones separated by one or more flow controllers, wherein the first particle line opens into the second fluidized-bed reactor above at least one flow controller; and wherein the system is configured to direct particles in a countercurrent flow to a fluid flow of a material feed.
