Definitions
- reaction is conducted in a fluid bed reactor under semi-continuous conditions.
- a semi-continuous reaction for example, the reactants are added and the reactor is run until about 50% of the silicon has been utilized. After about 50% silicon utilization, additional reactants of silicon and catalysts may be added.
- a semi-continuous reaction is in contrast to a batch mode reaction. With a batch mode reaction, all of the reactant components are combined and reacted until most of the reactants are consumed. In order to proceed, the reaction has to be stopped and additional reactants added.
- a fixed bed and stirred bed may both be run under batch conditions.
