hourly space velocity

基本解釋

The selectivity of C8 was increased with raising of weight hourly space velocity, but the conversion of butene was reduced.
進(jìn)料空速增大C8產(chǎn)物選擇性增大，但丁烯轉(zhuǎn)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.
而且在反應(yīng)溫度和空速越低、劑油比越大、反應(yīng)時(shí)間越長的條件下，催化裂化反應(yīng)受干氣比率的影響越明顯。
Reaction temperature, catalyst to oil ratio, weight hourly space velocity and feedstock nitrogen content affected the nitrogen content of spent catalyst and the nitrogen distribution in products.
反應(yīng)溫度、催化劑與原料油的質(zhì)量比、空速、原料氮含量都影響待生催化劑的氮含量和氮在產(chǎn)物中的分布。
