Abstract:
A method for transforming waste into carbon in a reactor, said method comprising: a) drying the waste by submitting said waste to a pressure of at least 3 bar, and a temperature of at least 250° C.; b) releasing the water vapor out of the reactor, and; c) carbonizing at least partially the waste by maintaining said waste during a period of time of at least 5 minutes to a pressure of at least 3 bar, and a temperature of at least 250° C., thereby obtaining carbon; and d) optionally separating non-organic material from the obtained carbon.
Abstract:
Described is a monolithic support member comprising channels with walls separating the channels and having a coating deposited thereon, the non-coated channels having a polygonal cross-section profile, wherein the mean thickness dC of the coating in a corner of said cross-section profile is smaller than or equal to the mean thickness dE of the coating on an edge of said cross-section profile plus 85 micrometer. Also described is a method for the preparation of such coated monolithic support member. Further described is the use of such coated monolithic support member as a catalytic article in automotive exhaust gas treatment.
Abstract:
A catalyst-coated support including a sheetlike support, a primer layer applied thereto and composed of nanoparticles composed of silicon oxide-comprising material, and at least one catalyst layer applied to the primer layer. The layers applied are notable for a particularly good adhesive bond strength and can be used particularly efficiently in heterogeneously catalyzed gas phase reactions, especially in microreactors.
Abstract:
A method for forming a photocatalyst substrate is disclosed, comprising the following steps. A substrate is provided. The substrate is disposed on a transporting device to transport the substrate. When the substrate is under a spray coating device, the spray coating device is used to form a photocatalyst layer on a surface of the substrate. When the substrate is under a heating device, the heating device is used to solidify the photocatalyst layer on the surface of the substrate.
Abstract:
An embodiment relates to a photocatalytic composite material comprising (a) a first component that generates a photoexcited electron and has at least a certain minimum bandgap to absorb visible light and a structure that substantially prevents the recombination of the photoexcited electron and a hole; (b) a second component that adsorbs/absorbs an oxide of carbon; and (c) a third component that splits the oxide of carbon into carbon and oxygen using the photoexcited electron.
Abstract:
