Aldehyde hydrogenation catalyst

Thread Content

Alcohol and aldehyde enter the reactor at 100 to 130°C. The alcohol and aldehyde are in trickle phase and hydrogen is in continuous phase, operating at a pressure of 5.0 to 8.38MPa. The alcohol is sprayed on the Harshaw Ni-1404T 3/16-inch catalyst and drips onto the catalyst, and then flows out from the bottom of the bed through liquid control. The hydrogen feed is pressure controlled into the top of the reactor. RCH3CHO + H2 Ni-1404 RCH2CH2OH alcohol hydrogenation reactor is a vertical vessel with an inner diameter of 800mm. It contains eight baskets of 2m height, each equipped with a redistributor. It can hold approximately 6.5t of catalyst in total. The specified size and catalyst volume provide satisfactory space velocity and residence time that have been proven by industrial operations. Ni-1404 is a hydrogenation catalyst with a cylindrical black particle appearance.: Size about Φ5mm (3/16”) ； Specification SPE103; Manufacturer: How to calculate the airspeed and dwell time of American Engelhand Company? What other data is needed? What is the catalytic mechanism? Thank you, fellow professionals! ! ! ! ! ! ! !
