气固流化床中非线性特性的多尺度分析

Deterministic chaos theory offers useful quantitative tools to characterize the non-linear dynamic behavior of a fluidized bed and the developed complexity theory presents a new approach to evaluate finite sequences. In this paper,the non-linear,hydrodynamic behavior of the pressure flutuation signals in a reactor was discussed by chaos parameters and complexity measures.Coherent results were achieved by our multi-scale analysis,which further exposed the behavior in a gas-solid two-phase system.

氯气干燥工艺优化

通过优化氯气干燥工艺,将1个泡沫筛板塔逐步改成氯气洗涤塔、两级钛冷器、两级填料干燥塔、一级泡罩填料复合塔,使氯气含水由0.05%~0.10%降低到0.005%以下,从而满足氯气用大型氯压机输送的要求,减轻对设备、管道的腐蚀。     

THE CALCULATION OF CRITICAL PROPERTIES OF MIXTURES FROM EQUATIONS OF STATE

The rigorous critical state criteria based on Helmholtz free energy is used with equations of state fordirect calculation of critical properties(T_c,P_c and V_c)of 44 binary and 5 ternary systems.Special at-tention is paid to systems containing polar component(s)and the improvement in critical volume prediction.For extending this method to polar systems,the recently developed Cubic Chain-of-Rotators equation ofstate has been applied.As compared with SRK and PR equations of state,the improvement in V_c pre-diction is most impressive.     

增强反应法制备的废轮胎胶粉增韧聚苯乙烯

用增强反应法制备机械破碎的废胎胶粉增韧的聚苯乙烯复合材料研究表明,当胶粉质量分数为40%时,其冲击强度比纯聚苯乙烯提高10倍,而拉伸强度比纯聚苯乙烯仍保持50%以上.胶粉粒度为40目时,增韧效果最佳,粒度分布对增韧效果影响不大.这表明用增强反应法制备机械破碎的废轮胎胶粉增韧的聚苯乙烯复合材料时,不必过分磨细废胎胶粉,也不必过分追求胶粉粒度均一.
