碳基材料吸附SO2与吸附VOCs工艺温度的匹配使其具有协同脱除的潜力。吸附剂孔隙结构及化学活性功能的有序组合是实现SO2/VOCs协同吸附的关键。本项目基于吸附质分子极性、尺寸与碳基吸附剂纳米孔空间特性间的匹配关系，提出了煤基活性焦孔结构分级官能化构筑技术构想。通过微孔-中孔/大孔的分级构筑以及不同尺度孔空间内特定官能团的定向分布，实现特定吸附质在不同尺度孔空间内的分级赋存与耦合吸附强化，从而有望极大地挖掘活性焦纳米空间利用潜力，提高活性焦对SO2/VOCs协同吸附过程吸附质输运、赋存容量。通过对 “活性焦孔结构分级官能化构筑机制”和“吸附质分级赋存及耦合吸附强化机制”两个关键科学问题的研究，为活性焦协同吸附SO2/VOCs技术提供理论基础。

The potential for simultaneous removal of SO2 and VOCs is provided by the match of processing temperatures for their adsorption in carbon-based materials. Orderly combination of pore structures and chemical activity of adsorbents is the key to SO2/VOCs simultaneous adsorption. Based on the matching relation between molecular polarity as well as size of adsorbate and spatial characteristics of nanopore structures in carbon-based adsorbents, the conceive of constructing hierarchical functionalized pore structures in coal-based activated coke is proposed. Via micro-mesopores/macropores hierarchical construction and specific functional groups rational distribution in various scales of pore structures, hierarchical storage and enhanced coupling adsorption in various scales of pore space can be realized, thus the capacity for adsorbates transportation and storage during SO2/VOCs simultaneous removal are expected to be improved significantly. By investigating the mechanism of the hierarchical functionalized construction of pore structures in activated coke and hierarchical storage and enhanced coupling adsorption of adsorbates, which are two critical scientific issues in our study, the foundation for SO2/VOCs simultaneous adsorption by activated coke is provided.
