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...
متن کاملApplication of carbon nanocatalysts in upgrading heavy crude oil assisted with microwave heating.
Heavy crude oil can be upgraded to lighter oil using several techniques. However, current methods usually require high temperatures, long reaction duration, and cause serious environmental pollution. This study shows that by using carbon nanocatalysts, heavy crude oil can be efficiently upgraded to lighter oil at a relatively low temperature of about 150 °C. The temperature of crude oil was inc...
متن کاملA Review of Laboratory-Scale Research on Upgrading Heavy Oil in Supercritical Water
With the growing demand for energy and the depletion of conventional crude oil, heavy oil in huge reserve has attracted extensive attention. However, heavy oil cannot be directly refined by existing processes unless they are upgraded due to its complex composition and high concentration of heteroatoms (N, S, Ni, V, etc.). Of the variety of techniques for heavy oil upgrading, supercritical water...
متن کاملUpgrading 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...
متن کاملNew Upgrading Process for Heavy Oil Using Iron/active Carbon Mixture Catalyst
The possibility of optimizing the composition and the structures of the nickel catalysts and the pretreatment and reaction conditions for carbon dioxide reforming with methane is investigated. The optimum catalyst and the pretreatment and reaction conditions are determined employing the orthogonal and uniform design methods. The optimum nickel catalyst gives promising catalytic performance in t...
