Abstract
Devices for controlling the reaction rate of a hydrocarbon to an acid or other intermediate oxidation product by pressure drop rate adjustments. The devices incorporate a reaction chamber, different means for monitoring miscellaneous parameters, means for feeding ingredients including gases, means for exiting products and gases, means for stopping the feeding and exiting of gases at predetermined time intervals, means for measuring the pressure drop rate during the period that the feeding and exiting of gases takes effect, and a controller, the function of which is to conduct adjustments in one or more of temperature, feeding rates of hydrocarbon, solvent, catalyst, promoter, and the like until the pressure drop rate and the reaction rate fall within desirable predetermined limits.
