    摘要： The invention relates to a process for the dehydrogenation of a feedstock comprising ethanol, using at least one multitubular reactor advantageously comprising a plurality of tubes comprising at least one dehydrogenation catalyst, and a calender, said feedstock being introduced into the tubes in gas form, at an inlet temperature of greater than or equal to 240° C., a pressure between 0.1 and 1.0 MPa, and a WWH between 2 and 15 h−1, wherein a heat-transfer fluid circulates in said calender at a flow rate such that the weight ratio of said heat-transfer fluid relative to said feedstock is greater than or equal to 1.0, and such that said heat-transfer fluid is introduced into said calender in gas form at an inlet temperature of greater than or equal to 260° C. and at an inlet pressure of greater than or equal to 0.10 MPa, and less than or equal to 1.10 MPa, and leaves the calender at least partly in liquid form.

    摘要： The present disclosure relates to electrolysis systems and methods. The teachings thereof may be embodied in methods and systems for the utilization of carbon dioxide and production of carbon monoxide. For example, a method may include: passing an electrolyte and carbon dioxide in front of a cathode through a cathode chamber; and removing electrolysis byproducts from an electrolyte/electrolysis product mixture using a catalytic filter system. The cathode may include material to reduce carbon dioxide. The process may generate a hydrocarbon compound or carbon monoxide as the electrolysis product and a formate as an electrolysis byproduct. The filter system may include a functionalized complex or a functionalized support material which catalyzes a cleavage reaction of formates (a) to hydrogen and carbon dioxide, or (b) to water and carbon monoxide.
