1·If you then take the petroleum feedstock and convert it very efficiently into the polymer, it can have a very low environmental footprint.
假如你到时能将得到的石油原料高效地转成高聚物，那么其只会具有非常低的环境足迹。
2·Why use trees, rather than maize or sugar cane, as a feedstock for ethanol?
为什么要选择树木而不是蜀黍或蔗糖作为乙醇原料？
3·For example, the E. coli naturally feeds on some of the fatty acids it produces, rather than using them as a feedstock for producing alkanes.
例如，大肠杆菌以其自身合成的一些脂肪酸为食，而不是以它们为原料来生产烷类。
4·What, then, is the most abundant feedstock for making ethanol which does not wreak havoc on food supplies, is environmentally friendly, economic and has all the enabling technologies in place?
那么，能够大量用于生产乙醇又不影响食物供应、环保、经济并且有所有可行技术的原料是什么呢？
5·Meanwhile the feedstock could be nice and cheap: Brazilian sugar.
同时，原料可以非常便宜：巴西甘蔗。
1·Commercial application showed that entrainment by feedstock was reduced, while the yield and quality of vacuum distillate were enhanced.
工业应用表明，可以减少进料雾沫夹带，提高减压馏分油的收率和质量。
2·Carbon nanotubes have been obtained by the floating catalyst method using the feedstock spray technique.
采用浮游催化法喷雾进料技术制备碳纳米管。
3·CGO were hydrotreated by RN 2 catalyst to remove N and S impurities and improve the quality. The hydrotreated CGO was proposed to be mixed with VGO as FCC feedstock after testing in the pilot plant.
采用脱氮活性高的RN-2 催化剂对管输油的焦化蜡油进行加氢处理，脱除其中的氮、硫等杂质及改善烃类组成后，进行催化裂化或与直馏蜡油混合作催化裂化进料。
4·The obvious coke increase on the catalysts in the 1 st and 2 nd reactors was one of the characteristics of feedstock having heavy com...
