中文摘要 | 本文對非理想混合的連續流動攪拌槽反應器中型式為 A+R→(η+1)R+ 產物的自身催化反應以及其整個反應速率式為γa=kCaCrr(p>0.r>0)的濃度多重 性已作分析。以反應級數p與r,Domkohler數θ'合參數A(A=m/n,m是完全混合體 積佔槽中總體積的分率,n是進入完全混合結橫流率佔總流率的分率)之多重穩態 準則已經導出。從我們的分析結果,非理想混合對反應級數r>1的穩態數目有影 響,但是對反應級數r<1的穩態數目無關。 |
英文摘要 | In this paper, the type A+R →(η+1) R + Products of concentration multiplicity for autocatalytic reactions and their overall rate expression-ra = kCapCrr(p>0,r>0) which where in a continuous stirred tank reactor (CSTR) with imperfect mix-ing, has been analyzed. Multiplicity criteria in terms of the reaction orders p andr, Darnkohler number ff and the mixing parameter A (A=m/n, m is the fraction ofthe total volume in perfect mixing and n is the fraction of the feed entered thezone of perfect mixing) were derived. From the results we analyzed, the non-ideal mixing had an effect on thenumber of steady states for the reaction orders r>l and r=l. However, the numberof steady slates for the reaction order r<1 is independent on the non-ideal mixing. |
