Correspondingly , xrd patterns revealed that carbon shells became graphitic somehow . the effects of organic solvents and catalysts / catalysts precursors on the structure and morphology of products were also investigated in this study . cyclohexane , instead of benzene , was proven to be a suitable solvent , as it would not pyrolyze in the reaction system 对金属催化剂(或前体)以及有机溶剂与产物形貌关系的研究结果表明，苯作溶剂在反应条件下易裂解并形成积炭，从而阻碍了多孔碳产物的继续生成，而选用环己烷可以避免类似的裂解反应。

In view of cost , the clarification effect and environmental protection , the cleaning system with coke as absorbent should be the fairly good choice that can produce less tar content and high quality household gas . the cost will be made fewer as well for the reason that coke in filter and clarifier - tank can be put into gasifier again to pyrolyze . in order to improve the clarification level and make preparations for generating electricity by means of biomass gasification technology 该试验装置克服了当前生物质焦汕催化裂解研究中采用焦油的某一种组分或者几种组分的混合物作为其模拟化合物的缺点，以热解反应器产生的生物质气为焦油来源，研究了生物质焦油的催化裂解原理、催化裂解中不同气化温度、裂解温度、停留时间对焦油成分和催化裂解效果的影响，并对比以前的试验结果进行了初步的理论分析。
