Pd/C上松香催化加氢反应动力学
Kinetic Study for Catalytic Hydrogenation of Rosin over Pd/C
摘要
Abstract
Catalytic hydrogenation of rosin was studied with rosin as raw material, modified Pd/C as catalyst and oil No. 200 as solvent. The effects of internal and external diffusion were eliminated by improving the type of stirrer, adding solvent oil No. 200, raising rotational speed to more than 600 r/min and reducing granularity of catalyst at 10-20 μm. The changes of components with reaction time were traced on-line at temperature 403 K to 433 K and pressure 5 MPa by capillary gas chromatography. The pseudo-homogeneous reaction kinetics of catalytic hydrogenation of rosin was studied. The result shows that the reaction velocity of catalytic hydrogenation of rosin is the first order with respect to abietic acid concentration. The intrinsic kinetic equation is r = 1. 13 × 105exp( -5. 904 × 103/T)C1, and the activation energy is 4.909 × 104 J/mol.关键词
