本文着重介绍高温高压下开放流动体系内矿物-水反应动力学的最新研究成果。在研究了连续流动体系中方解石-水的反应速度方程后又在稳态操作的化学动力学实验中发现了偶存于其中的非稳态动力学过程。同时用轴向弥散模型和叠层反应器研究了萤石和钠长石反应动力学机理。本文还研究了不同温压、流速、介质和不同的溶液性质对反应速度的影响及控制因素。
This article focuses on the latest research results of mineral-water reaction kinetics in an open flow system under high temperature and pressure. After studying the calcite-water reaction rate equation in continuous flow system, we find out the non-steady-state kinetic process in the steady-state chemical kinetics experiment. The reaction kinetics of fluorite and albite was also studied by axial dispersion model and stacked reactor. This paper also studied the influence of different temperature and pressure, flow rate, medium and different solution properties on the reaction rate and the control factors.
