Temperature and Concentration Distributions in Fixed-bed Catalytic Reactors : Comparison of Calculated with Experimental Results

Fixed-bed catalytic reactors are most widely used for vapor-phase reactions catalyzed by solid particles. Although theoretical studies concerned with the design method have been extensively performed, few systematic experimental substantiations have been presented. The purpose of this paper is to obtain the necessary data for the reactor design and to evaluate the accuracy of the design method. The radial temperature profiles and the mean conversions at various catalyst heights were measured in a 5.0 cm I.D. reactor where the hydrogenation of benzene takes place on a nickel-kieselguhr catalyst. The basic design data, the rate of reaction and the heat transfer characteristics in a fixed bed were also presented. A numerical design method used here is similar to those developed by Smith and Walas with suitable modification. Profiles of temperature and conversion predicted by the numerical method were in good agreement with the experimental data

30-Item General Health Questionnaire Scores in Male and Female University Freshmen

The thirty-item General Health Questionnaire (GHQ30) was conducted on 1,432 university freshmen twice in June 1998 and in January 1999 to investigate their mental health conditions after matriculation. After classifying the results by the time of investigation and gender, logistic regression analysis was performed to extract question items correlated with high GHQ scores. As a result, male students investigated in June showed the correlations among high GHQ scores and the following 5 items:subjective health conditions (SC), satisfaction with matriculation (SM), enthusiasm for studies (ES), living with (family or alone) (LW), and the difference between whether they passed the entrance examination directly upon graduation or not (EE), otherwise, that in January correlated with SC and SM only. Female students investigated in June showed the correlations among high GHQ scores and the following 3 items: SC, SM, and ES, otherwise, that in January correlated with SC, ES, and LW. In addition, factor analysis was performed after classifying the replies to GHQ30 by the time of investigation and gender. As a result, uselessness was obtained as the first factor in all students, and the following factors were respectively obtained as the second factor: human relationship and low activity in male students investigated in June, low activity in male students investigated in January, intimacy and high-tension in female students investigated in June, and low-tension in female students investigated in January
