Abstract
Methods and devices for controlling the reaction rate of a hydrocarbon to an acid or other intermediate oxidation product by pressure drop rate adjustments. The pressure drop rate measurements arc conducted at predetermined time intervals, after stopping the feeding and exiting of gases. The pressure drop at a predetermined time interval is measured or the time it takes for the pressure to drop by a certain degree. Adjustments are then made in one or more 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.
