Abstract：The clean and efficient conversion and utilization of heavy oil is a strategic issue to safeguard energy security and sustainable development of national economy and society. The project has proposed a new technique to utilize heavy oils with high efficient and clean method of "Deep separation of heavy oil， catalytic conversion of distillates， and comprehensive utilization of residues". The comprehensive utilization of residues is one of the key scientific problems to realize the industrialization of new technique. Focusing on this scientific problems， the following research is carried out. The thermodynamics and kinetics of gasification reaction of heavy oil residue is firstly investigated. The transport， flow and agglomeration behavior of residue particles is studied， and the methods to improve the fluidization performance of residue particles are found out. The flow and reaction characteristics of the gasification of residues slurry is also explored. The research will lay the foundation for the industrial application of heavy oil residue gasification process.

Key Words：Heavy oil；Residue；Gasification
