COVER

The essence of heavy oil processing is molecular composition and conversion. The benefit of a refinery is based on the molecules they buy and sell. Refining at molecular level has been a common concept both in academic and industrial communities. However, it is challenging for chemists to understand the composition of heavy petroleum and the detailed mechanisms of refining processes.
