Upgrading of Heavy Oil or Vacuum Residual Oil : Aquathermolysis and Demetallization

Viscosity Reduction of Heavy Oil by Aquathermolysis with Coordination Complex at Low Temperature

To seek for new catalysts for the aquathermolysis of crude oil under relatively low temperature, in this paper, a series of Mannich base-transit metal coordination complexes was synthesized and used in aquathermolysis of heavy oil as catalyst. The results show an evident viscosity reduction by 84.2% for the heavy oil reacted at 180 C for 24 h catalyzed by the Ni(II) coordination complex. The gr...

Simultaneous valorization and biocatalytic upgrading of heavy vacuum gas oil by the biosurfactant‐producing Pseudomonas aeruginosa AK6U

Heavy vacuum gas oil (HVGO) is a complex and viscous hydrocarbon stream that is produced as the bottom side product from the vacuum distillation units in petroleum refineries. HVGO is conventionally treated with thermochemical process, which is costly and environmentally polluting. Here, we investigate two petroleum biotechnology applications, namely valorization and bioupgrading, as green appr...

Upgrading of Pyrolysis Bio-oil: A Review

The increase in the population of the planet and the rapid economic growth and, consequently, the high consumption of energy has created many environmental problems in the globe. Due to these reasons and the lack of renewability of these fossil fuels, there has been a steep trend towards the production of renewable fuels from natural sources, one of which is the production of energy from biomas...

Characterization of pore coking in catalyst for thermal down-hole upgrading of heavy oil

Heavy oil and bitumen are a potential alternative energy source to conventional light crude. However, recovery of these resources can have substantial environmental impact. Downhole upgrading offers the prospect of both improving recovery, and decreasing environmental impact. However, use of catalysts to enhance downhole upgrading is limited by the need for one that can survive the extreme coki...
