An autoclave reactor having polycrystalline diamond bearings. The autoclave reactor can include a housing for containing at least one reaction material therein, a motor disposed within the housing, an agitator connected to the motor for stirring the at least one material within the housing, the agitator having a shaft connected to the motor at one end thereof, and at least one bearing disposed adjacent to the shaft or adjacent to the connection of the shaft to the motor, the at least one bearing being made of polycrystalline diamond. A process for making low density polyethylene (LDPE) can include introducing ethylene to the autoclave reactor disclosed herein and polymerizing the ethylene within a housing of the reactor to provide the low density polyethylene.

The current invention relates to a plasma reactor comprising: a reactor space, an axial gas inlet suitable for fluid flow in an axial direction, said axial inlet comprising radial injection slits for discharging a jet of gaseous mixture into said reactor space, a downstream gas expansion disc, which extends radially from the coaxial inlet and is located downstream of said radial injection slits with respect to said axial direction, plasma generating means suitable for ionizing a gaseous medium within said reactor space, and a cylindrical reactor container, coaxial with said gas inlet, encompassing said reactor space, said reactor container comprising outlet means. The invention further relates to a multistage reactor. The invention also relates to the use of said plasma reactor.

The invention relates to a flow element for transferring fluids comprising a capillary cartridge (1) having an integrated capillary line (3). The capillary cartridge according to the invention (1) has a ring-shaped channel (8) and securing grooves (6, 6), wherein the flow element is characterized in that the capillary line (3) is arranged in the ring-shaped channel (8). The ends of the capillary lines (3) are connected to connection elements (9) in which securing grooves (6, 6) are secured in a positive locking manner. The flow elements according to the invention contribute toward improved manageability and effectiveness of components. In a preferred embodiment, the flow elements are used as a distribution system in the form of a plurality of capillary cartridges (1-1, 1-2, . . . ). Such distribution systems are of technical importance in the field of catalyst testing apparatuses with reactors arranged in parallel.
