Abstract

Aim\ Based on experimental results

the intrinsic kinetic models of low pressure methanol synthesis over a domestic Cu based catalyst

QML01

were established. Methods A series of the intrinsic kinetic experiments for QML01 catalyst was carried out in an integral micro reactor under following conditions: 5 MPa

(224~272) ℃ and feed compositions CO 0.051 3

.142 3/CO\-2 0.006

.092/H\-2 0.625 5

.774 8 (mole fraction). The model parameters were searched by means of Simplex Marquardt optimal method and Merson integral method. Results\ The parameters of intrinsic kinetic models for QML01 catalyst were estimated

respectively. Conclusion\ Statistical test shows that the intrinsic kinetic models established for QML01 catalyst not only agree well with the experiment results

but are highly acceptable and reliable also.
