The method for recycling carbon dioxide according to the present invention includes: injecting a reaction gas containing carbon dioxide and a carbon raw material into a rotary heating furnace; reacting the reaction gas and the carbon raw material with each other in the rotary heating furnace to generate a hydrocarbon precursor containing carbon monoxide; and converting the hydrocarbon precursor into a hydrocarbon compound, thereby exhibiting excellent conversion rate of carbon dioxide.

A method for enabling gas exchange and chemical reactions with one or more liquid streams contained in a reactive process vessel are provided. One or more exchange layers within the process vessel can be composed of both collector media and releaser media. The exchange layers allow elements to facilitate increased performance of vessel operations by promoting gas component mixing and diffusion. Improved rates of gas component exchange mean less coking and more gas components available for reaction.

The present invention relates to different liquid distributors for monolith in multiphase applications. The present invention more particularly relates to distributor devices in the form of a single injection and multiple injection pipe distributors; shower head distributor comprising a plurality of holes for plunging liquid; a packing of spherical particles with a pre-distributor to split the liquid into manifold streams, before entry into the monolith bed. The present invention provides liquid distributors for monolith in multiphase applications providing improved liquid distribution into the monolith bed resulting in uniform fluid flow in each channel so as to make maximum use of the catalyst surface area.

The present invention relates to a removable basket for a catalytic reactor comprising a horizontal base (1) and a plurality of vertical side walls (2) and/or at least one ellipsoidal side wall, and a plurality of vertical chimneys (3, 4) that are open at their lower (5) and upper (6) ends, each chimney comprising a lower part (7) comprising the lower end fastened to the base and extending between the side walls, in which a first chimney comprises an upper part (8) extending above the side walls, and the upper part of the first chimney is suitable for being inserted into a lower part of a chimney of another removable basket. The present invention also relates to a filtration and distribution device comprising said removable basket, a reactor comprising said device, and a hydrotreating and/or hydrocracking process using said reactor.

An apparatus includes a conduit with two process fluid inlets at one end of the conduit, one process fluid outlet at an opposing end, a heat exchange medium inlet, and a heat exchange medium outlet. One of the fluid inlets includes a tube extending into the conduit and a perforated node at the end of the tube, and the other of the fluid inlets is arranged up stream of the perforated node. The apparatus further includes hollow tubes positioned longitudinally within the conduit between the two process fluid inlets, the process fluid outlet, the heat exchange medium inlet and the heat exchange medium outlet. In addition, the apparatus includes a collection vessel positioned proximate the fluid outlet and fibers extending through each of the hollow tubes, wherein one end of the fibers is secured to the perforated node and the other end of the fibers extends into the collection vessel.
