In an aspect, the present disclosure provides a method for the oxidative coupling of methane to generate hydrocarbon compounds containing at least two carbon atoms (C.sub.2+ compounds). The method can include mixing a first gas stream comprising methane with a second gas stream comprising oxygen to form a third gas stream comprising methane and oxygen and performing an oxidative coupling of methane (OCM) reaction using the third gas stream to produce a product stream comprising one or more C.sub.2+ compounds.

The hydroprocessing reactor internals (HRI) have reduced height compared to standard HRI designs. The HRI height reduction is achieved by a more open design of a rough liquid distribution tray so that the required spaces above and below the tray for vapor flow are reduced. The hydroprocessing reactor quench zone internals comprise a collection tray, a rough liquid distribution tray, and a vapor-liquid distribution tray. Fluid mixing occurs above both the collection tray and the rough liquid distribution tray.

The present disclosure relates to a reactor containing of catalyst particles, a layer of fibrous catalyst particles support below said catalyst particles and a lower means of structural support below said catalyst particles with the associated benefit of such a reactor having increased space for catalyst particles, compared to a reactor with inert particles supporting the catalyst particles.

A device for bringing a target medium into contact with a carrier fluid comprises a chamber comprising a circumferential wall, a bottom wall and a top wall forming an enclosure for containing the target medium while contacting the carrier fluid, the chamber being substantially rotationally symmetric with respect to an axis of symmetry and adapted for remaining mechanically static in operation of the device. The device comprises a fluid inlet for injecting the carrier fluid into the chamber in a substantially tangential direction with respect to an inner surface of the circumferential wall, and an outlet. The device comprises a fluid distributor in the chamber for enabling the injected carrier fluid to pass through the distributor in a substantially inward radial direction, the distributor being substantially rotationally symmetric and adapted for rotating around the axis when driven by a transfer of momentum between the injected carrier fluid and the distributor.
