Abstract: A solid powder reactor includes: a reaction kettle, including a hollow kettle body and covers; an agitating device, including an agitating shaft and blades, wherein the agitating shaft is arranged in the kettle body and the blades are fixed on the agitating shaft; and a heating system, including a kettle body heater and an agitating heater, wherein the kettle body heater is fixed on the kettle body and the agitating heater is arranged on the agitating device. While the agitating device and the kettle body are driven to agitate, by a driving device fixedly arranged outside the reaction kettle, the heating system heats materials in the reactor. The present invention is applicable to solid reaction of solid powders. The materials containing attached water or not are both feasible, and the materials can directly enter the reactor and react. Compared with conventional solid reactors, the present invention increases the production efficiency.

Abstract: Techniques are provided for operating a reactor during a catalyst transition period. The instantaneous reaction rate during a catalyst transition period can be determined using real-time measured process variables, and material balance calculations to provide an instantaneous reaction rate in approximately real time. According to certain embodiments, a material balance can be performed on the reactor system using a continuous ideal stirred tank reactor to determine the fractions of each type of catalyst that are present in the reactor, as well as the overall weight percent of catalyst in the reactor. A controller can then calculate the overall instantaneous reaction rate based on the respective catalyst fractions and the overall weight percent of catalyst in the reactor. The catalyst feed rate can then be adjusted based on the determined instantaneous reaction rate to maintain the instantaneous reaction rate within desired limits during a catalyst transition period.
