I M Al Nashef has received his PhD in Chemical Engineering from University of South Carolina, Columbia, SC, USA in 2004. After obtaining his BSc in Chemical Engineering from the University of Jordan in 1984 Nashef worked as teaching and research assistant at Kuwait University and United Arab Emirates University where he participated actively in different research areas. He has joined King Saud University, Riyadh, Saudi Arabia, after obtaining his PhD from the University of South Carolina in 2004. In 2011, he was promoted to Associate Professor. He co-authored more than 60 peer-reviewed journal publications. In addition, he received 7 patents from US and EU Patent Offices. He is also a recipient of several prestigious awards including King Abdullah Award for best invention in 2013. He supervised 9 graduate students.
In the last two decades, Ionic Liquids (ILs) have attracted considerable attention in many fields of scientific research. ILs have drawn an increasing interest due to their unique physical and chemical properties that showed a great potential as an alternative media in many potential applications. ILs are defined as low melting point, lower than 100 °C, salts consisting of organic cations and organic/inorganic anions both of which are large ions and held together by electrostatic interactions. ILs has very low vapor pressure, non-flammable, tunable and can dissolve both polar and non-polar compounds. Owing to their low vapor pressure ILs were qualified as green solvents. However, the green affiliation of ILs is now contested by many research groups. The hazardous toxicity and the very poor biodegradability of many ILs have been reported in the literature. ILs with high purity is also required since impurities, even in trace amounts, affect their physical properties. These drawbacks together with the high price of common ILs delayed their industrial applications and new concepts were strongly needed in order to utilize these systems in a more rational way. To overcome these drawbacks, a new generation of solvents, named Deep Eutectic Solvents (DES), has emerged as alternative to ILs in many applications. Formation of these DESs can be obtained by simply mixing together two or more components that can be chosen to be cheap, renewable and biodegradable. These compounds are capable of forming a eutectic mixture with a melting point lower than that of each individual component. DESs are generally liquid at temperatures lower than 100 °C. Many DESs have similar physical-chemical properties to those of ILs, while being much cheaper and environmentally friendlier. Owing to these advantages, there is now of growing interest in DESs in many fields of research. DESs are chemically tailorable solvents since they can be designed by properly combining various quaternary ammonium or phosphonium salts with different Hydrogen Bond Donors (HBD) or complexing agents. Hence, task-specific DESs with different physical-chemical properties can be prepared. It should also be noted that although components of DESs are potentially reactive chemicals, their auto-association by a hydrogen bond drastically limits their reactivity, allowing their use in many fields of research. In this work, we discuss the application of both ILs and DESs in petroleum refining and petrochemical processes. Examples include, but are not limited to, separation of aromatics, de-sulfurization, de-nitrification and carbon dioxide capture.

Xu Zhao is the Deputy Director of Market Analysis and Strategy Research Center of Refining and Chemical Industry in CNPC Economics and Technology Research Institute (ETIR). He has completed his Graduation from China University of Petroleum, Beijing, majoring in Chemical Engineering and Technology. He is mainly engaged in oil refining technology research and development strategy research.
Global energy is entering into a transformation period- clean, low-carbon and intelligent. The development of refining industry play a key role for the sustainable development of oil and gas industry, we need to increase the investment to promote technological process to achieve the sustainable development. The technological innovations will focus on the heavy oil processing, clean fuel production and refining and petrochemical integration. With the increasing of heavy oil processing in refineries, we have better understanding of the nature of heavy oil; hydrogenation and decarburization technologies will get new progress. The standards of clean fuel will be stricter; the low cost and high de-sulfurization activity will be the hot spot of catalyst research. Using refining and petrochemical integration to optimize the industrial chain, it will deliver more chemical raw materials and high value-added chemical products. At present, CNPC boasts 28 refinery enterprises; have established 12 large-scaled refinery bases, 7 large-scaled ethylene bases and 3 large-scaled arene production bases. Mission of CNPC is to contribute energy and create harmony and the strategy of CNPC is resources, markets, internationalization and innovation. Keeping the technological innovation, CNPC has some technology progress on the three aspects mentioned above. CNPC’s high-end production technology in naphthenic base thickened oil has made a breakthrough in the difficult deep processing of thickened oil all over the world, realized a historical leap in deep processing technology in super-thickened oil within China and constructed a production base for deep processing of thickened oil and naphthenic base products in Karamay Petrochemical Company. CNPC’s complete production technology in clean gasoline and diesel oil meeting China’s IV/V Standards have become a major technology in oil quality upgrading of CNPC to provide clean oil for pollution control and emission reduction. CNPC’s large-scaled complete technology of refining series have broken technological monopoly, CNPC’s large-scaled complete ethylene technology has been successfully applied and realized stable operation for more than three years in which has made CNPC become one of the 6 major ethylene patent holders in the world. Looking into future, intelligent refineries will lead the global refining industry into an intelligent age.
