    摘要: This invention is to a microreactor type of reaction and analysis system. The system includes a chemical reaction chamber having internal conduits through which a chemical reactant, such as a reaction gas, can be fed. The conduits for transporting fluids such as reactant, carrier gas and balance gas are in appropriate communication such that the amount of reactant going directly to a catalyst located in the reaction chamber can be optimally controlled. The system is highly useful for studying the kinetics of a chemical reaction.

    摘要: This invention is directed to controlling regenerator temperature in an oxygenate to olefin process. Because a significant amount of heat can produced in the regenerator during the regeneration process, at least a portion of the heat must be removed to keep the system from getting too hot. This invention removes heat during the regeneration of the catalyst, using appropriate circulation of catalyst between the reactor and the regenerator. Sufficient circulation can eliminate the need for the use of a catalyst cooler in the regeneration system.
