520	3		_aBench-scale evaluation of hydrotreating catalysts may lead to lower apparent activities than found in commercial operation. Especially for shaped catalysts deviating results are obtained. From bench-scale test results and liquid holdup measurements, it is concluded that these problems are related to the method of testing. The low superficial mass velocities in the test unit lead to inefficient catalyst utilization. It is demonstrated that reversing the direction of oil flow from downflow to upflow gives a much improved catalyst utilization comparable to those in commercial units.
