| 摘要: |
In order to find an efficient and feasible technological rout to dispose and utilize deoiled asphalt (DOA, a byproduct of solvent deasphalting process), the co-pyrolysis/gasification of DOA with lignite was investigated. A series of isothermal co-pyrolysis experiments were conducted in a fixed bed reactor to observe the characteristics of the chars yields and the pattern of the blends. Then a set of non-isothermal experiments were performed by thermogravimetric system to evaluate the gasification characteristics of the chars of lignite, DOA and the blends. It was observed that the DOA has the lowest reactivity for its low surface area, high graphitic carbon structure and low ash content. The reactivity of the co-pyrolysis chars was found higher than that of the calculated, this clearly demonstrating that the synergetic effect is existed during the co-gasification process. |
