文獻:The activity measurements were carried out in a fixed-bed quartz reactor using a 0.25 g catalyst of 40–60 meshes. The feed gas mixture contained 500 ppm NO, 500 ppm NH3, 5% O2 and helium as the balance gas. The total flow rate of the feed gas was 300 cm3min−1, corresponding to a GHSV of 64,000 h−1. 問題:這里的64000 h-1是怎么算的啊?求教 |
