【 摘 要 】

References(7)Cited-By(2)A laboratory scale flow-type reactor—a coiled tubular flow reactor (CTFR)—was designed to obtain kinetic data of three-phase reaction, at high gas and liquid velocities with long liquid contact time, as is fond in commercial reactors. Kinetic measurements with CTFR were compared to those with an improved stirred basket-type batch reactor (BTBR) to examine the presence of the external effects in CTFR such as interphase mass and heat transfer resistances, and axial dispersion. Hydrodesulfurization of straight-run light gas oil and hydrogenation of 1-methylnaphthalene were performed for the comparison. It was verified that the reaction rates without external effects can be determined using CTFR under reaction conditions where the volatility of liquid-phase components is low, because kinetic data with CTFR and BTBR closely agreed with each other in such conditions.
