摘要：
Simple dehydrogenation of 1-butene to form 1,3-butadiene was performed at 550-620C using Pt/SnO2-Al2O3 catalysts (SnO2 = 0-23 wt%) in the presence of steam. The low SnO2 content catalyst (7 wt%) showed high selectivity to 1,3-butadiene, but the catalytic activity dramatically decreased due to coke formation during the dehydrogenation. With increasing SnO2 content in the catalyst, the deactivation was suppressed by a decreasing amount of coke. The high one-pass yield (30%) was obtained at 620C using the Pt/SnO2-Al2O3 catalyst containing 18.0 wt% SnO2 without serious deactivation of the catalyst. [GRAPHICS]
