Gum content of light and middle distillate fuels-jet evaporation method 轻质及重质馏出燃料中胶质含量测定法-喷射蒸发法
Light petroleum distillate, generally known as naphtha, was the logical choice. 轻石油馏分,如石脑油是合乎逻辑的选择。
The two-stage hydrogenation refining and reforming of coal-derived light distillate 煤液化轻油馏份的两段加氢精制和重整
The original combined process for C 4 processing to produce high octane value gasoline in Lanzhou Petrochemical Company was made up of MTBE, polyisobutylene, gas fractionation, polymerization and alkylation units, taking FCC light C 4 distillate as feedstock. 兰州石化公司生产高辛烷值汽油的碳四加工联合工艺,原采用催化裂化生产的轻碳四馏分,由MTBE、聚异丁烯、气体分馏、叠合和烷基化等装置组成,流程较长。
The unit is a five-column process and its main products purity are as follows: purified propylene 99.6%, isobutene in light C4 distillate above 21%, which both are feedstock of polypropylene and polyisobutene units downstream. 该装置为五塔设计流程,主要产品精丙烯的纯度为99.6%,轻碳四馏分中异丁烯纯度不小于21%,为下游的聚丙烯、聚异丁烯等化工装置提供原料。
A numeric method for computing limiting concentration of light component in the distillate of binary batch distillation under constant reflux ratio and hold-up in the column is introduced. 介绍了采用恒回流比操作方法,在塔顶、塔板持液时,间歇精馏二元理想混合物,馏出液中轻组分极限浓度的数值计算方法。
Study on the cocatalyst for improving light distillate yield of residue catalytic cracking 提高渣油催化裂化轻质油收率的助剂研究
The light distillate ( IBP~ 80 ℃) of refining gasoline is used as etherification material, the lifetime of catalyst is improved obviously. 用精制后的轻馏分(初馏点~80℃)作为醚化原料,催化剂寿命明显提高。
