Apparatus and process for determining the hydrogen consumption during hydrogenation

摘要

With an apparatus for feeding hydrogen and for determining the hydrogen consumption, hydrogenation on a laboratory scale can be carried out automatically at constant hydrogen pressure and at the same time the hydrogen consumption can be measured if a measuring tube (6) with float (9) is connected between two valves (Y1, Y2) of a connecting line (1, 19) of hydrogen supplier and consumer (3) and if the float (9) is assigned at the upper and lower measuring tube ends (5, 11) initiators (10, 12) which are connected to a control system (15) actuating the valves. <IMAGE>
