| titleOfInvention | A kind of catalytic hydrogenation preparation hexahydrophthalic anhydride technique |
| abstract | A kind of catalytic hydrogenation of the invention prepares hexahydrophthalic anhydride (HHPA) technique, using SiO 2 For carrier, infusion process is prepared for Pd-NiO/SiO 2 Catalyst, in trickle bed reactor, tetrahydrophthalic anhydride catalytic hydrogenation prepares hexahydrophthalic anhydride (HHPA), has probed into optimum reaction condition and technological parameter.Using SiO 2 Loading type Pd, Ni binary metal catalyst, suitably reduction catalyst activity, increase hydrogen partial pressure, effectively improve purpose product hexahydrophthalic anhydride (HHPA) selectivity.On hydrogen point, in, in lower three positions, into drip-flow reactor, reaction layout is more uniform controllable, side reaction is reduced, catalytic hydrogenation is exothermic reaction, increases the internal recycle rate of hydrogen in reactor, hydrogen is as thermophore, timely transfer reaction heat reduces the generation of side reaction it is possible to prevente effectively from hot-spot is existing. |
