Kinetics of reactions of C8 olefins on HY zeolite

Kinetics and selectivity of reactions of 1‐alkenes on HY zeolite: The influence of chain length

“…We observe the appearance of all linear olefins and note that their distribution approaches equilibrium at comparatively low levels of conversion (in this study conversion is defined as species present other than the feedstock and its linear isomers). We further note that there is expected to be little difference between adsorption constants for 1-hexene and 2-or 3-hexenes (Abbot and Wojciechowski, 1987b) so that even at very low conversion, where equilibrium for linear olefins may not exist, the lack of equilibrium would not be expected to influence the reaction to any significant degree.…”

“…. (1) -dx -_ More recently we have also shown (Abbot and Wojciechowski, 1987b) that Equation (1) can be applied to reaction of linear and branched C8 olefins on HY zeolite at 300°C thus establishing a broad range of validity for Equation (1) and laying the basis for quantitative comparisons of the calculated parameters.…”

“…T reactions of paraffins on solid acid catalysts (Abbot and Wojciechowski, 1987a;Corma et al, 1985a,b;Haag et al, 1982;Pansing, 1965;Voge, 1958) but far less is known about the kinetics of reactions of olefins on these catalysts (Abbot and Wojciechowski, 1987b;Haag et al, 1982). Although olefins are not generally present in crude oil (Venuto and Habib, 1978), they are produced as primary products from cracking of paraffins and cycloparaffins (Germain, 1969).…”

“…We have previously applied our kinetic model to the reaction of isomeric C8 olefins on HY at 300°C (Abbot and Wojciechowski, 1987b). Under these conditions, we found that the dominant reaction processes were cracking and skeletal isomerization for 2,4,4-trimethylpentene and 1-octene respectively.…”
