Abstract: The absorptive removal of carbon dioxide from biogas using a scrubbing liquid in which carbon dioxide is chemically bound proceeds by heating the loaded scrubbing liquid, occurring after the absorption, to a temperature at which liberation of CO2 begins. Immediately thereafter, the loaded scrubbing liquid is fed to at least one centrifugal separator for separating off the gas phase from the liquid phase, wherein methane and dissolved fractions of CO2 escape via the gas phase. After separation is complete, the gas phase is passed into the absorber unit and the liquid phase is further heated to the temperature required for desorption and fed to the desorption unit for regeneration.

Abstract: A coating agent comprises a binding agentcontaining at least one acrylate copolymer (A) with carboxyl groups and/or at least one acrylate copolymer (B) with epoxide groups, the acrylate copolymers (A) and (B) being obtained by solution polymerization using less than 5% by weight based on the total weight of monomers of one or more polysiloxane macromonomers a.sub.1 having a number-average molecular weight of 1000 to 40,000 and on average 0.5 to 2.5 ethylenically unsaturated double bonds per molecule; and one or more epoxy resins.

Abstract: A water-soluble protein conjugate modified by saccharides is covalently bound to a carbohydrate backbone via a saccharide group. Such protein conjugates modified by saccharides can be produced in a simple way by polymerizing a vinylsaccharide and conjugating in a known way the poly(vinylsaccharide) obtained in this way with the protein, which is preferably an enzyme. The protein conjugates according to the present invention are stable over long time periods at a high enzymatic activity and also in aqueous solution and are thus particularly suitable for use in test kits.
