The selectivity of C8 was increased with raising of weight hourly space velocity, but the conversion of butene was reduced.
进料空速增大C8产物选择性增大，但丁烯转化率降低；
The impact of dry gas on FCC reaction becomes increasingly pronounced with lower reactor temperature and lower hourly space velocity, greater catalyst to oil ratio and longer reaction time.
而且在反应温度和空速越低、剂油比越大、反应时间越长的条件下，催化裂化反应受干气比率的影响越明显。
