摘要： The invention relates to a method for dosing catalysts into a reactor, wherein the catalyst is initially suspended in hydrocarbon in a receiving container, the suspension thus obtained is maintained in motion by agitation and fed into the actual reactor via a three-way dosing valve and an ejector. The suspension containing the catalyst is firstly discharged from the receiving container with the aid of a pump and continuously circulated, whereby the suspension is returned to the receiving container via the three-way dosing valve in a closed line system, whereupon the pressure inside the receiving container is adjusted so that it is 0.1 - 30 bars higher than the pressure in the reactor and the suspension is continuously introduced into the reactor by pulsing operation of the by now opened three-way dosing valve by a throughflow measuring device which controls the three-way dosing valve and by a downstream ejector.
