     mesoporous carbon (mc) prepared by a surfactant-templating method was treated with different h2so4concentration (x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0 m) for use as a support (mc-x) for rhenium catalyst. rhenium catalysts supported on h2so4-treated mesoporous carbons (re/mc-x) were then prepared by an incipient wetness impregnation method, and they were applied to the liquid-phase hydrogenation of succinic acid to tetrahydrofuran (thf). the effect of h2so4 treatment on the physicochemical properties and catalytic activity of re/mc-x catalysts (x = 0, 0.2, 0.4, 0.6, 0.8, and 1.0) was investigated. it was observed that mc-xsupports showed different pore characteristics depending on h2so4 concentration. as a result, re/mc-xcatalysts showed different rhenium particle size. in the liquid-phase hydrogenation of succinic acid to tetrahydrofuran (thf), conversion of succinic acid and yield for thf showed volcano-shaped curves with respect to h2so4 concentration. thus, an optimal h2so4 concentration was required to achieve maximum catalytic performance of re/mc-x. yield for thf in the hydrogenation of succinic acid increased with decreasing rhenium particle size of re/mc-x catalysts. among the catalysts tested, re/mc-0.4 with the smallest rhenium particle size showed the highest yield for thf.
