A catalyst was developed for the hydrofining of raw naphthalene. It could run for 2800 hr in a 1.5L reactor of flowing system under 320—340℃, 40kg/cm~2, 0.8hr~(-1) and gas/oil=500 by vol. with C deposit of only about 5% when using coke oven gas as hydrogen source.The effect of the acidity and the pore size of the catalyst on the coke formation was discussed.

In this paper a thermodynamic method has been used to calculate the efficiency of coal liquefaction based on various kinds of coal. It is assumed that hydrogen source (both enthalpy and hydrogen) is provided from the same kind of coal, when it is converted into transportable fuel, Tue results from calculation for the most kinds of coal indicate that inorder to upgrade coal to fuel of H/C=1.6~2.2 the actual fraction of coal used for liquefaction is about 60~75%. According to the International Classification of Hard Coal, the coal class 4, 5, 6 and 7 have higher liquefaction effeciency; but the lignite containing much more oxygen gives the poor percentage effeciency.

本文假定在煤加氢液化制造液体燃料的过程中,原料煤和氢均由同一种煤提供。通过热力学计算,比较了我国几个煤种的煤炭在液化过程中液化效率的理论值。计算结果表明,液化效率大约在60~75%之间,其中,按国际硬煤分类的4、5、6、7类煤(相当于我国煤分类法中的气煤、肥煤、长焰煤、弱粘煤等)液化效率高,褐煤则由于含氧量高而液化效率低。

In a previous communication,we had reported the result of under the direction of the electron theory of catalysis of photosynthesis,with the compound of titanium dio- xide power and oxidizing iron powder as catalyst,water as hydrogen source,air as nitrog- en source and near ultraviolet light as energy source to reduce dinitrogen to ammonia under the common temperature and pressure.Bnt,so far as we know,on the surface of the earth,not only about half of the quantity of sunlight is visible light and the quantity of ultraviolet is small,but also the photonic energy of ultraviolet light is bigger than that of visible light.Therefore,any possibilty of finding some catalysts which can fulfil the dinitrogen fixation and reduce it to ammonia in the visible light would have great significan- ce both in theory and in practice.We prepared a series of catalysts.One of those is a ca- dmium sulfide containing 10% molybdenum compounding with iron powder as reported prev- iously. We proved that this catalyst can use the dinitrogenof air as nitrogen source with ~(15)N_2- enriched air.We also found this catalyst can use the visible light,until red light as ener- gy source when the green or red light is used iuthe monochromatic light experiment respe- ctively. When we used sunlight directly or used a lens to aggregate sunlight to irradiate sam- pies,the product yield of ammonia were about 26 and 110 μ mol/gram catalyst·hour res- pectively.

前文报导了用二氧化钛和氧化了的铁粉的混合物作催化剂,在常温、常压下、用水作氢源,空气作氮源,利用近紫外光作能源,模拟兰绿藻等的光合固氮,把分子氮固定下来,并还原为氨。本文报导的是一种能利用可见光的、含有钼等杂质的硫化镉和前文相似的铁粉混合作催化剂,在常温、常压下,通过~(15)N 的同位数实验,以及绿光和红光的实验,证明它的确在可见光下可以用水作氢源,空气作氮源,固定分子氮并还原为氨。如果稍加聚光,在太阳光下,每克催化剂每小时的产率在100微克分子以上。文中也初步探讨了形成机理。
