Abstract
DISCLOSED IS A HETEROGENEOUS CATALYTIC HYDROGENATION PROCESS COMPRISING HYDROGENATING A SUBSTANCE TO BE HYDROGENATED UNDER TRICKLE FLOW CONDITION USING A REACTION TOWER CHARGED WITH A SOLID CATALYST, IN WHICH HYDROGEN GAS AND A LIQUID PHASE CONTAINING THE SUBSTANCE TO BE HYDROGENATED ARE MADE TO FLOW CO-CURRENTLY DOWNWARD FROM ABOVE, WHEREIN DYNAMIC LIQUID PHASE HOLDUP AMOUNT PER UNIT CATALYST EXTERIOR SURFACE AREA OF THE CATALYST CHARGED IN THE REACTION TOWER IS 0.005 x 10-3 TO 0.14 x 10-3 M3/M? AND THE CATALYST HAS A CATALYST STRENGTH OF 1.0 KG OR MORE, AS DETERMINED BY THE FOLLOWING FORMULA CATALYST STRENGTH = A-2?? WHEREIN A REPRESENTS A MEAN VALUE OF MINIMUM STRENGTHS OF 100 CATALYST SAMPLES MEASURED ACCORDING TO THE METHOD DESCRIBED IN "TEST METHOD FOR CRUSHING STRENGTH" OF JIS Z-8841-1993" AND?? REPRESENTS A MEAN STANDARD DEVIATION. FIGURE 1
