开放式反应器中的反应动力学和封闭式反应器之间的串联转移
Reaction kinetics in open reactors and serial transfers between closed reactors
摘要:
将反应网络的动力学和热力学理论推广到连续流搅拌釜式反应器(CSTR)和串联转移的失平衡动力学。根据它们的化学计量矩阵,确定了两种动力学的守恒律和网络的环。它示出的CSTR和串行传输动态是等价的限制,其中传输之间的时间间隔趋于零成比例的比例的分数的新鲜转移的解决方案。这些结果说明了有限的交叉催化反应网络和一个无限的反应网络描述聚合物之间的质量交换。序列转移动力学通常用于生命起源研究背景下的分子进化实验。本研究是脱落的串行传输参数在这些实验中所发挥的作用的新的光。
英文摘要:
Kinetic theory and thermodynamics of reaction networks are extended to the out-of-equilibrium dynamics of continuous-flow stirred tank reactors (CSTR) and serial transfers. On the basis of their stoichiometry matrix, the conservation laws and the cycles of the network are determined for both dynamics. It is shown that the CSTR and serial transfer dynamics are equivalent in the limit where the time interval between the transfers tends to zero proportionally to the ratio of the fractions of fresh to transferred solutions. These results are illustrated with finite cross-catalytic reaction network and an infinite reaction network describing mass exchange between polymers. Serial transfer dynamics is typically used in molecular evolution experiments in the context of research on the origins of life. The present study is shedding a new light on the role played by serial transfer parameters in these experiments.
