Cleaning the water-methanol fraction from methanol on the industrial catalyst NTK-4
There are scheme and description of the apparatus for catalyst testing in cleaning of water-methanol fraction (methanol content 4,9- 5,1 wt.%). It is shown that reactor design features allow to test fine fractions and whole tablets with a diameter of 4,5-5,0 mm, 4,0- 5,0 mm in height. They obtained the test results of the industrial catalyst NTK-4 in the process of cleaning water-methanol fraction on fine catalyst fraction (1,0-1,6 mm) and whole tablets at a volume rate of 1250 h-1 (gas mixture), temperatures of 200, 250, 300 °C and 8-hour test. It is shown that the catalyst NTK-4 performs high activity on fine fractions and the tablets at 250 and 300 °C. The degree of purification at 250 °C on the fraction is 0,990 and 0,988 on the tablets with initial content of methanol, 5,1 wt.% in watermethanol fraction.
