Abstract: The invention relates to a method for generating a CO and an H2 product fraction, comprising the following steps: a) reforming (A) a hydrocarbon-containing feed flow (1) for generating a CO- and H2-rich synthesis gas (5), b) adsorptive separation (C) of undesirable constituents, in particular H2O and CO2, from the synthesis gas, c) separating (D) the adsorptively treated synthesis gas (7) into a CO product fraction (8) and an H2-rich fraction (9), wherein the H2-rich fraction (9) is supplied at least partially and/or at least intermittently to the adsorptive separation unit (C) as a regenerating gas, d) adsorptive hydrogen separation (E) from the H2-rich fraction (10), wherein the separated hydrogen constitutes the H2 product fraction, and e) supplying the residual gas fraction (3) from the adsorptive hydrogen separation unit (E) as heating gas to the reformation (A), wherein the reformation process (A) is operated depending on the composition of the residual gas fraction (3) supplied as heating gas to the re

Abstract: A tire tread for pneumatic vehicle tires comprising tread blocks of a central block row separated from one another by inclined grooves which consist of two angularly extending groove sections which meet at the central circumferential plane. Furthermore, two circumferential grooves extend at an acute angle to the circumferential plane of the tire in the region of the blocks which bound them at the sides.
