Abstract:
The present invention describes a device that firstly allows temporary storage of a certain quantity of catalyst and, secondly, the putting back into circulation of said quantity in the regenerative reforming installations following an interruption in the circulation of the catalyst.
Abstract:
The present invention describes a process for a controlled conversion of a biomass feedstock, wherein the process comprises the steps of: loading the biomass feedstock to at least one reactor; liquefaction of the biomass feedstock into a monomer and/or oligomer sugar mixture in said reactor by treatment in hot compressed liquid water (HCW) at sub- and/or super-critical condition; and removal of the monomer and/or oligomer sugar mixture, being the product molecules, to avoid continued detrimental decomposition.
Abstract:
The invention relates to the production of acrolein and/or acrylic acid from glycerol, and more particularly to a method for continuous production of a stream comprising acrolein by dehydration of glycerol, comprising cycles of reaction and regeneration of a dehydration catalyst.

Abstract:
Synthesis gas is produced according to this invention using a combination of steam reforming and oxidation chemistry. The process incorporates the use of solids to heat the hydrocarbon feed, and to cool the gas product. According to the invention, heat can be conserved by directionally reversing the flow of feed and product gases at intermittent intervals.
Abstract:
A unit for producing and processing phosgene, said unit being configured for at least one maintenance mode and at least one production mode and comprising a structure which defines a confined space in a production mode, said confined space being sub-divided into at least two sub-spaces, wherein (i) at least one sub-space contains at least one apparatus for producing phosgene; (ii) at least one sub-space, other than the at least one sub-space according to (i), contains at least one apparatus for processing phosgene; (iii) the structure comprises at least one openable and lockable access means for temporary access of at least one of the apparatuses according to (i) or (ii) from outside the structure in a maintenance mode.

Abstract:
The present invention describes a catalytic reactor operating as a moving bed to manage interruptions in the circulation of catalyst while at the same time avoiding mechanical damage to the contact means containing the catalyst. The invention also concerns a refining or petrochemicals process using the reactor in accordance with the invention.
Abstract:
A method for processing plastics waste, in particular polyolefines, and a device for processing plastics waste, in particular polyolefines, are used especially in the industrial utilization of plastics waste. The method consists in that a primarily refined charge after being fed into a reactor (6) is fluidized and cracked during forced progressive-rotational movement coinciding with heating. A gas-steam fraction obtained during a utilization process is continuously guided out to a cooling system whereas impurities are periodically guided out from the reactor (6) to a waste tank (22).
