摘要: The mechanisms of the dehydration reaction 1-decanol to 1-decene over precipitated gamma-alumina (γ-Al2O3) by means micro-kinetic modeling approach were investigated. Experimental data collected in temperature range 533–608 K, while retention time was varied from 0.029 0.15 h. γ-Al2O3 catalyst synthesized using a traditional precipitation method. yield both internal olefins and increased with increasing temperature. Conversely, di-n-decyl ether decreased An increase olefins. These experimental correlated well rate equation that assumes formation be reversible dual-site reaction. It is reasonable state isomerization single-site apparent activation energy for 1-decene, obtained Arrhenius plot data, 102 ± 2 kJ/mol.
