Claim:
1. A process, comprising: providing distributor device for distributing liquid and gas in a multiple-bed downflow reactor; wherein the distributor device comprises: a substantially horizontal collecting tray provided with: a central gas passage and liquid passages around the central gas passage; a swirler, which swirler: is located above the collecting tray around the central gas passage, and is provided with vanes defining a swirl direction and being arranged to impart a swirling motion to gas passing through the central gas passage so that the gas leaves the central gas passage as a swirl swirling in said swirl direction around a vertical swirl axis; one or more ejection nozzles located above the collecting tray and arranged for ejecting, in an ejecting direction, a quench fluid into the gas before said gas enters the swirler; wherein the ejection direction is represented in an orthogonal set of three ejection vectors comprised of a radial ejection vector extending perpendicular to the swirl axis, an axial ejection vector (A) extending parallel to the swirl axis and a tangential ejection vector extending tangentially with respect to the swirl axis; introducing the quench fluid through the one or more injection nozzle; and passing the gas through the swirler; characterized, in that the ejection nozzle is directed such that the tangential ejection vector, T) of the ejection direction of the ejected quench fluid is directed opposite to the swirl direction.
