2017年7月11日 · Here, we investigate two petroleum biotechnology applications, namely valorization and bioupgrading, as green approaches for valorization and upgrading of HVGO. The Pseudomonas aeruginosa AK6U strain grew on 20% v/v …

2022年3月30日 · Petroleum heavy vacuum gas oil (HVGO) containing 10 wt.% of petroleum wax was hydrocracked at 390–430 °C and under the pressure of 18 MPa over a Ni W/amorphous silica-alumina catalyst in a continuous-flow fixed-bed reactor. The hydrocracking of a reference feed (neat HVGO) was carried out under the same reaction conditions.

流化催化裂化（Fluid catalytic cracking，又作Fluidized-bed catalytic cracking ，或Fluidized catalytic cracking ；简称FCC），是石油精炼厂中最重要的转化工艺之一。 被广泛用于将石油 原油 中高 沸点 、高 分子量 的 烃类 组分转化为更有价值的 汽油 、 烯烃 气体和其他产品。 石油 烃类 的裂化最初都是通过 热裂化 （thermal cracking）完成；如今热裂化已几乎全部被催化裂化所取代，因为催化裂化可以产生更多具有高 辛烷值 的汽油。 此外，催化裂化也能产生更多拥有 碳 …

2020年6月5日 · The performance of both ebullated bed H-Oil vacuum residue (VR) hydrocracking and fluid catalytic cracking (FCC) of vacuum gas oils (VGO) is interrelated. The increase of H-Oil unit reaction...

2024年7月1日 · Herein, we have investigated the steam catalytic cracking of heavy VGO (HVGO) blends with naphtha (NAPH) and gas condensates (GCON) in a microflow fixed-bed reactor using synthesized nano-ZSM-5 catalyst for increased light olefins yield.

摘要： 为了研究工艺参数对加氢尾油裂解过程中结焦的影响,在加氢尾油裂解实验装置上考察了裂解温度、进料质量流速和水油质量比对炉管结焦速率的影响。 利用SEM、EDS、DSC-TG及EA对结焦试样进行表征和分析。 结果表明,结焦速率随温度升高从2.16mg/ (cm 2 ·h)逐渐增大到7.90mg/ (cm 2 ·h);结焦速率随流速的增大从3.36mg/ (cm 2...

HVGO is conventionally treated with thermochemical process, which is costly and environmentally polluting. Here, we investigate two petroleum biotechnology applications, namely val-orization and bioupgrading, as green approaches for valorization and upgrading of HVGO.

2015年4月8日 · 北京化工大学硕士学位论文sRT一Ⅳ（Hc）型裂解炉中HVG0裂解过程的模型化与模拟摘要乙烯是石油化学工业重要的基础有机原料之一，它的产量标志着一个国家石油化学工业的发展水平。 由于乙烯在石油化学工业中所起的主导作用，因而它的生产规模、成本、生产稳定性和产品质量等都会对整个石油化工联合企业起到支配作用。 所以，乙烯装置成为关系全局的核心生产装置。 乙烯绝大部分是由石油烷烃裂解而生产，乙烯裂解炉是乙烯生产中的关键设备，三 …

The H-Oil HVGO is the most coke-producing gas oil, probably because it contains the highest level of heavy higher-molecular-weight polynuclear aromatic hydrocarbons [28,33, 41]. The average ...

These findings suggest that HVGO can be potentially exploited as a carbon-rich substrate for production of the high-value biosurfactants by P. aeruginosa AK6U and to concomitantly improve/upgrade its chemical composition.
