Abstract:
The invention relates to a device (100) for preparing a substance stream (1.1) containing hydrogen and methane, comprising the following components: (i) at least one heat exchanger (KS1) for cooling a substance stream (1.1) to be prepared; (ii) at least one separating unit (A, A1, A2, A2') for purifying the substance stream (3) to be prepared into a hydrogen and methane-rich substance stream (5); (iii) at least one cooling unit (KS2) for cooling the hydrogen and methane-rich substance stream (5); and (iv) at least one cryogenic gas separating unit (KS3) for separating the hydrogen and methane-rich substance stream (6) into at least one hydrogen-rich substance stream (7) and at least one methane-rich substance stream (8, 9). The invention further relates to a method for preparing a substance stream.
Abstract:
The invention relates to a method for regenerating a supported hydrogenation catalyst containing ruthenium, wherein the catalyst is treated with steam and subsequently dried. The invention further relates to an integrated method for hydrogenating benzene to form cyclohexane in the presence of a supported catalyst containing ruthenium, comprising the catalyst regeneration steps in addition to the hydrogenation step.
