Using the 200-300℃ fraction from a small-sized continuous fractionraing device made in Japan as his raw material, the author conducts an experiment on its catalytic reforming behaviour in a FYX-1 autoclave. The effect of reaction temperature, initial H_2 pressure, reaction time and catalyst on desulfuration and denitrogenation of the oily liquid from coal liquefaction is studied.

Using the 200-300℃ fraction from a small-sized continuous fractionraing device made in Japan as his raw material, the author conducts an experiment on its catalytic reforming behaviour in a FYX-1 autoclave. The effect of reaction temperature, initial H_2 pressure, reaction time and catalyst on desulfuration and denitrogenation of the oily liquid from coal liquefaction is studied. The desulfuration and denitrogenation performance of the catalysts: 3722, 3761 and Mo-Ni-P which act on the oily product, as well as the change in its viscosity with time in different media and at different temperatures under the action of the three catalysts, is also studied. It is found that long reaction holding time and high holding temperature favour desulfuration and denitrogenation of the oily liquid while intensify its evaporation; high pressure favours denitrogenation and reduces its evaporation. Mo-Ni-P catalyst is a highly effective desulfurer and denitrider and in addition, has a favourable degradation effect on the dehydrogenated products and makes the viscosity og the reformed oily liquid less susceptihle to the effect of the existence of a N_2 atmosphere.

本文叙述了以日本小型连续装置馏程为200~300℃的液化油作试验材料,在FYX—1型高压釜中催化加氢改质的试验。讨论了不同的反应温度、氢初压、反应时间,催化剂对液化油加氢脱S,脱N的影响,评价了3722,3761,Mo—Ni—P三种催化剂对液化油的脱S,脱N能力,以及三种催化剂对液化油在不同介质、不同温度下粘度随时间的变化情况,结果表明:反应时间长,高温有利于液化油脱S,脱N,但液化油气化率高;高压有利于液化油脱N,且能降低气化率。Mo—Ni—P催化剂脱S,脱N效果好,加氢改质产品轻质化效果佳,改质液化油在N_2气氛下粘度变化较小。

The effects of preparation factors of Ni-Mo catalyst with DX-30 active carbon as carrier on hydro-desulfurization and hydro-denitrification of coal liquefaction oil were studied. The results show that the catalyst of 99.8% desulfurization efficiency and 63.2% denitrification efficiency were obtained. They are higher than those by commercial petroleum refining catalyst with Al_2O_3 or SiO_2 as carrier. It was found that the soaking order of active components in the catalyst,content of components,atomic ratio of Ni to Ni +Mo, temperature of heat treatment and pore structure of carrier all have influence on desulfurization and denitrification activity of the catalyst.Specific absorbate was used to measure the number of surface acid/base sites and its distribution on the catalysts by pulse chromatography.

本文研究以DX-30活性炭为载体的镍-铝催化剂制备因素对煤液化油的加氢脱硫脱氮反应的影响。实验结果表明,所制备的催化剂对加氢脱硫脱氮有很好的活性,在选定的实验条件下,脱硫率达到99.8%,脱氮率达63.2%,均高于以氧化铝、二氧化硅为载体的石油精制商品催化剂。研究发现,催化剂活性组份的浸渍顺序,含量、Ni/(Ni+Mo)原子比、催化剂焙烧温度、孔径分布等因素均影响催化剂的脱硫脱氮活性。在制备催化剂时,当先浸镍后浸钼,NiO-MoO_3涂量为35%,Ni/(Ni+Mo)原子比为0.29,焙烧温度为400℃时,催化剂的脱硫脱氮活性最高。实验中采用脉冲色谱法,以有特征集团的试剂分子为吸附质,测定了不同方法制备的催化剂表面酸碱中心集团的数目及分布情况。随催化剂制备方法的不同,催化剂表面酸碱中心数目及分布情况有很大差别。催化剂表面L酸中心有利于脱硫脱氮。

The paper investigates the performance of catalyst Ni-Mo,which uses activatedcarbon DX-30 as a carrier for hydrogenation of Liquid products from coal Lique-faction,and preparation factors that influence the performance of catalyst.Expe-rimental results indicate that under the same reaction conditions,catalyst Ni-Mo/DX-30 is better than catalysts 3665 and 3822 in hydro-desulfurization and hydro-denitrogenation,both of which are regarded as effective catalysts in this country.It is found that performance of catalyst is affected by such factors as impregnatingprocedure of active components,quantity of coating,atomic ratio of Ni/(Ni+Mo),core distribution and specific surface area.The optimum process is as follows:thecomponents are first immersed in Ni,then in Mo,coated by 35% NiO-MoO_3 byweight,and the value of Ni/(Ni+Mo) is 0.29.The number of acid and basic active cores and their distribution in the cata-lyst when prepared by different methods and under different conditions are mea-sured by pulse chromatography method,using solvent with characteristic group as anabsorbent.The number of acid and basic actives cores and their distribution varygreatly when the preparation method and processing parameters are different.It is found by electronic microscope that addition of NiO to MoO_3 will des-troy the original crystal,and produce a new loose crystal,which results in betterdispersion of active components and hence improved activity of the catalyst.

本文研究以Dx-30活性炭为载体的镍-钼催化剂在煤液化油加氢反应中的催化性能,并探讨了催化剂制备因素影响催化性能的原因。实验表明,所制备的催化剂对加氢脱硫脱氮有很好的效果,在相同的反应条件下,脱硫脱氮活性均佳于目前国内认为效果比较好的3665,3822催化剂。研究发现:催化剂活性组分的浸渍顺序、涂量、Ni/(Ni+Mo)原子比、孔径分布和比表面积均影响催化剂的性能。制备催化剂时,当先浸镍后浸钼,NiO-MoO_3涂量为35%,Ni/(Ni+Mo)原子比为0.29时,催化剂活性最高。在研究中还采用脉冲色谱技术,以有特征基团的试剂分子为吸附质,测定不同方法、条件下制备的催化剂表面酸碱中心的数目及分布情况。随催化剂制备方法、条件的不同,催化剂表面酸碱中心数目及分布有很大差别。借助电子显微镜发现,在 MoO_3中加入 NiO,破坏了原来的晶体结构,生成新的较松散晶体,提高了活性组分的分散度,改善了活性。
