Abstract

A method for processing a gas stream comprising CO2 and at least three other gases selected from CO, H2, CH4, n-C2, n-C3, n-C4, n-C5, n-C6, O2, H2O and N2, the method comprising utilising the gas stream in a catalytic chemical vapour deposition process, thereby reducing the CO2 content of the gas stream.

Abstract

The invention relates to a screw conveyor, comprising a housing (2) connected to a material feed (1) and comprising a conveying screw (3), the hollow screw shaft (4) of which is connected to a coolant feed (12). In order to ensure advantageous conveying conditions, the hollow screw shaft (4) according to the invention has radial passage openings (10) for an inert gas as coolant in the conveying region of the conveying screw (3).

Abstract

Process and device for trapping oxygen-containing noxious gases from combustion gases. The process comprises a feeding of phosphorus into an heat exchange chamber, the reaction of said phosphorus with said oxygen of said oxygen-containing noxious gases and generating a second thermal energy, and a partial transformation of the second thermal energy into mechanical work and/or electrical energy into the heat exchange chamber.
