1. Professor Weibin Fan «Conversion of methanol into liquid fuels and chemicals». (October 30 in 1500)

The conversion of methanol to liquid fuels, as a non-petroleum route to get valuable chemicals from multifarious carbon resources such as coal, natural gas and biomass, has attracted extensive attentions in recent years. Zeolite is considered as one of the most effective catalyst for methanol conversion and its catalytic performance in methanol conversion is closely related to its framework structure and acidic properties. Therefore, the detailed catalytic mechnism and traget product selectivity of a given zeolite in methanol conversion can be effectively regulated through finely tuning the pore structure, acidic property and mophology of zeoltie. Methanol and dimethyl ether (DME) were first dehydrated in the acid site of zeolite, forming the methoxymethyl cations (CH3OCH2+), which gave ethene or propene as the initial alkene products. After that, the hydrocarbon pool species, such as methylcyclopentadienes and methylbenzenes, were rapidly constructed and methanol conversion reaction was initiated through the aromatics cycle or olefin cycle. The results of DFT calculation demonstrate that ethene and propene can be produced in nearly the same probability via the aromatic cycle in the acid site of intersection cavity of ZSM-5 zeolite, whereas propene and C3+ alkenes are the dominant product via the alkene cycle. The relative contribution of the aromatic and alkene cycles is probably related to the acid strength of a zeolite. Stronger acidity is more favorable to the propagation of the aromatic cycle and produce more ethene and aromatics. 27Al MQ/MAS NMR, in situ DRIFTS, in situ UV-vis and 12C/13C methanol switching measurement suggest that the variation of Al siting has a significant influence on the catalytic performance of zeolites in methanol conversion. More Al atoms located in the straight channel can enhance the alkene cycle that produces more propene and butene; in contrast, an increase in the fraction of Al in the intersection cavity of ZSM-5 and ZSM-11 can then promote the aromatic cycle and facilitate the formation of ethene and aromatics. Moreover, the Al siting or the distribution of acid sites in zeolite can also be controllably adjusted by adding proper content of boron (B), germanium (Ge) or alkali metal ions during the synthesis.

2. Professor Wenzhong Shen «Functional carbon materials derived from coal asphaltene». (October 31 in 1200)

Asphaltene is a mixture of heavy organic polymers, which is a by-product of coal tar and coal direct liquefaction process. It is mainly composed of C and H elements, and also contains a small amount of S, N, O and other heteroatoms. Compared with the precursors of carbon materials like polymer, coal and biomass, asphaltene is a liquid phase carbon source and has the advantages of abundant raw materials, easy doping and compounding. Due to its complex structure and wide molecular weight distribution, it is difficult to obtain regular and orderly structures during polymerization, condensation and carbonization. The structure of asphaltene determines its chemical properties and applications. Understanding its formation rules and structural controlling is the basis of efficient utilization of asphaltene. Asphaltene with controllable structures, concentrated molecular weight distribution and low heteroatom content is an excellent precursor to synthesize new functional carbon materials.

This report is mainly about asphaltene fundamental study and applications, including the separation and structural control, thermal condensation control, preparation of pitch-based carbon fiber and functional porous carbon materials.
