油页岩炼制过程油气提质增效技术创新与系统集成

Oil shale is a kind of non-conventional resources of abundant reserve with a potential to mitigate the shortage of oil supply. Nowadays exploitation and utilization of oil shale in China suffers from serious challenges, such as small scale, low oil yield, low-quality oil products, and high pollutant emissions. .In this project, we will investigate new oil/gas upgradation technologies of the oil shale refineries, expand the downstream chemical products chain. We will try to establish fundamental “unit-process-system” models at multi-scales, analyze retorting mechanism and mass-energy conversion fundamentals, and identify bottlenecks of exsisting oil shale retorting processes integratd with new oil/gas product upgradation processes. .One of the key research focuses is to investigate a new process of integrating chemical looping gas regeneration for hydrogen production and further oil hydrogenation. Furthermore, multi-objective optimization is conducted for the oil shale refinery integration system. It is aimed to find out the most optimal solution to achieve high efficiency, best economic profit, and least emissions of oil shale resources utilization.
