Preparation of support for catalysts e.g. hydrogenation catalyst involves producing hydrogel; milling to give finely particulate hydrogel having particles with specific particle size; producing slurry; and drying the slurry

摘要

Preparation (P1) of a support for catalysts involves: producing hydrogel; milling to give finely particulate hydrogel; producing slurry based on finely particulate hydrogel; and drying the slurry. The finely particulate hydrogel comprises (vol.%): particles having particle size greater than 0 - =3 mm (at least 5); particles having particle size greater than 0 - =12 mu m (at least 40); and/or particles having particle size greater than 0 - =35 mu m (at least 75). Preparation (P1) of a support for catalysts involves: a) forming a hydrogel; b) milling the hydrogel to give a finely particulate hydrogel; c) producing a slurry based on the finely particulate hydrogel; and d) drying the slurry comprising the hydrogel to form the support. The finely particulate hydrogel comprises (vol.%): particles having particle size greater than 0 - =3 mm (at least 5); particles having particle size greater than 0 - =12 mu m (at least 40); and/or particles having particle size greater than 0 - =35 mu m (at least 75).
