摘要
用快速热解气相色谱法(Py-GC)以及热解气相色谱-质谱(Py-GC-MS)联用技术,鉴定了山西蒲县藻煤藻类体的热解产物组成。利用等温一级反应动力学模型,计算了蒲县藻煤藻类体热解产物中正构烷烃、正构烯烃、苯(B)、甲苯(T)、萘以及热解总产物(A_T)等组分生成动力学参数,探讨了这些动力学参数与生烃的关系。
The composition of pyrolysis products from Puxian alginite is determined6ythe sequential flash pyrolysis gas chromatography and pyrolysis gas chromatography-massspectrometry. The pyrolysis products are mainly n-paraffin ranging from carbon 6 to 28 andalkyl aromatics with short chain length. The kinetic parameters of generating n-alkanes,n-alkenes, benzene, oluene,naphthalene,gaseous components(C_1~C_6),light hydrocar-bons(C_7~C_(14)), heavy hydrocarbons(C_(15)~C_(28))and the total products from the Puxian algi-nite pyrolysis can be calculated by an isothermal first order reaction kinetics model. The re-sults show that the generation rate of different molecular groups from Puxian alginite pyroly-sis, is sequenced as follows,i.e,the light hydrocarbons(C_7~C_(14)) including aromatics(k_(500)=0 2022 s ̄(-1)),the heavy hydrocarbgons(C_(15)~C_(28))mainly composed of paraffinic monomers(k_(500)=0. 1789 s ̄(-1), and the gaseous hydrocarbons(C_1~C_6)(k_(500)=0.1236 s ̄(-1)).The relationsbetween kinetics parameters and the hydrocarbon formation are also discussed in this study.
