To produce high-purity 1-octene, the dehydration of 1-octanol was performed over a dual-bed catalytic system comprising Al2O3 and Ba/Al2O3 catalysts. The influence catalyst weight on activities single-bed systems initially investigated at liquid hourly space velocities (LHSVs) 7–168 h−1 400 °C. For system, 1-octene selectivity decreased with an increase in weight. Although increased owing to anti-Saytzeff effect, its yield limited due low conversion. efficiency subsequently by varying bed ratio (i.e., xAl–yBa). 40Al-60Ba afforded higher conversion (95.3%) productivity than LHSV 56 h−1. Moreover, 10Al-90Ba high exhibited LHSVs 7–28 h−1, while also yielding product. lower toward after 100 h, offered stable performance regardless small reductions yield.
