Abstract: Research and development of a 20t/a scale pilot experimental device for continuous gas-phase catalytic dehydrogenation of dipentene, including technical process, equipment process, and key equipments, was introduced. Design of key equipments, such as preheater, gasifier, and reactor, was mainly discussed. The structure and properties of common sprayer and ultrasonic sprayer in gasifier were studied in detail. The pilot experimental device was run practically. The p-cymene yields were respectively 92.65%-97.09%(common sprayer/260-280℃) and 97.04%-98.16% (ultrasonic sprayer /260-280℃).

Key words: dipentene, catalytic dehydrogenation, p-cymene, pilot experimental device
