| 中文摘要 | 本文主要在研究基於分線法的數值技巧用以模擬固定床反應器,文中採用核心遞縮模式來描述固相的非催化性氣固反應,同時也探討無輻向分散的絕熱固定床反應器在氣相中的質能方程式。本文以H2S與ZnO在絕熱固定床反應器的問題作為範例,俾便釋明應用本文方法以解析其溫度和濃度在反應器內的縱向分佈。由本文所得結果可提供一通則以分析氣固反應器模式,同時也提供一合宜數值技巧來處理氣體濃度分佈,並定量縱向分散對於暫態、溫度及濃度分佈的效應。 |
| 英文摘要 | A numerical technique based on the method of lines for the simula-tion of a fixed bed reactor was explored. A shrinking model was used to describe gas-solid noncatalytic reaction for the solid phase. The mass and energy balance equations with negligible radial dispersion terms in an adiabatic fixed bed reactor were also investigated for the fluid phase. Example problem in an adiabatic fixed bed reactor for H2S-ZnO reac-tion was solved and demonstrated its concentration with temperature distribution along the axial direction. The results of this work provided a general idea for analyzing models for gas-solid reactors, and a suitable numerical method to deal with gas concentration profile and to quan-tify the effects of axial dispersion in the transient concentration and temperature profiles. |
