摘要: This invention is to a process and system for controlling solids distribution in a gas-solids reactor. Solids distribution is controlled by controlling electrical charges between solid particles flowing between conductive surfaces within a gas-solids reactor. The electrical charges are controlled by conventional means such as by grounding the opposing conductive surfaces, or by applying a voltage to one of the opposing conductive surfaces.
