| Abstract: | ![]()
Hydrogenation of soybean oil was carried out by nickel/ silica catalysts in a newly developed rotating packed disk reactor (RPDR). The rotation of a catalyst-filled disk facilitated hydrogen transfer into the liquid phase and mixing in the reactor, resulting in an improved threephase reaction. Performance of RPDR in a batch operation was studied by varying temperature, pressure, nickel concentration in the oil, and disk rotating speed. The overall reaction rate increased with these variables, but the selectivity of linoleic acid was high when the hydrogen transfer controlled the reaction on the catalyst. |
