The dehydrogenation of tetralin over Ni-Mo/Al2O3, Fe2O3/Al2O3, Fe2O3 and FeS2 has been shown in this investigation to be a typical consecutive reversible reaction, with a small amount of 1, 2-dihydronaphthalene as an intermediate. On the less-active catalyst Fe2O3, a trace of 1, 4-dihydronaphthalene (DHN) is also formed-the more active the catalyst, the lower the concentration of DHN. The rate of dehydrogenation rises with an increase of the partial pressure of tetralin, and declines with an increase of the...

The dehydrogenation of tetralin over Ni-Mo/Al2O3, Fe2O3/Al2O3, Fe2O3 and FeS2 has been shown in this investigation to be a typical consecutive reversible reaction, with a small amount of 1, 2-dihydronaphthalene as an intermediate. On the less-active catalyst Fe2O3, a trace of 1, 4-dihydronaphthalene (DHN) is also formed-the more active the catalyst, the lower the concentration of DHN. The rate of dehydrogenation rises with an increase of the partial pressure of tetralin, and declines with an increase of the partial pressure of hydrogen. It was observed that DHN is much more active than tetralin and naphthalene, and in the presence of a catalyst, it can be converted rapidly into naphthalene and tetralin. The fact that hydrogen can accelerate the hydrogenation of DHN is thought to be the main reason for its inhibiting action on the dehydrogenation of tetralin. In the presence of a catalyst, 1,4-DHN is unstable and can be isomerized into 1,2-DHN very quickly. The different catalysts studied have almost the same order of activity for dehydrogenation of tetralin, conversion of DHN and hydrogenation of naphthalene. On the hypothesis that the reaction is a consecutive one on the catalyst surface and that the adsorbed DHN is a very active intermediate, a reaction model was deduced. The equilibrium constants of adsorption and the rate constants of the catalytic reaction were calculated. The curves so calculated fit very well the experimental data, thus showing the validity of this model. Certain experimental results were explained in the light of this model and the related parameters.

四氢萘在Ni Mo/Al_2O_3、Fe_2O_3、FeS_2上常压脱氢是典型的连串可逆反应,1,2-二氢萘及微量的1,4-二氢萘是反应的中间产物.脱氢反应速度随四氢萘分压提高和氢分压下降而提高.对二氢萘反应性能的考察表明它具有比四氢萘和萘高得多的反应活性,能迅速地催化转化为萘和四氢萘.氢加快二氢萘的加氢是它阻滞四氢萘脱氢的主要原因.各种催化剂对四氢萘脱氢、二氢萘转化和萘高压加氢都具有基本相同的活性顺序.根据可逆连串表面反应的历程及表面吸附的二氢萘为非常活泼的反应中间体的假设,作者推导了动力学模型,计算得到各反应物在Ni Mo/Al_2O_3、Fe_2O_3、Fe_2O_3/Al_2O_3上表面吸附常数和表面反应速率常数,并进行模拟计算.理论计算与实验能很好地吻合,证明了模型的合理性.模型及参数也进一步解释了一些实验事实.

In this paper, the underground tunnels especially those with prefabricated circu-lar linings of reinforced segments or blocks, by shield construction in the saturatedsilty soft ground of Shanghai area are discussed. On the basis of field measurementsand laboratory tests, the Chain Theory that the distribution of soil pressure aroundthe tunnel is approximately uniform, the elastic theoryof circular ring under loosening soil pressure, and the design method considering the stiffness of the ring jointsare proposed, the design models and parameters of the stratum and structures aresuggested. This mehtod has better confomity with the site realities than the conventionalway. lt yields thinner lining sections, less reinforcements and simpler jointwork, thus helping lead to the advantage of engineering cost and construction speed.

本文介绍了上海地区含水饱和淤泥质软土地层中地下工程的设计理论,主要为盾构法施工的装配式圆形钢筋混凝土管片和砌块衬砌结构。在现场量测和室内相似试验的基础上,提出了周围土压接近均匀的链条理论、松动压力下弹性圆环理论和考虑接头刚度的设计方法,并建议了设计时采用的地层和结构的模型及参数。采用本文方法,比习用设计方法更符合客观实际,可以使衬砌减薄、钢筋用量减少,接头构造简单,达到进一步节省投资和加快建设的效果。
