A new hydroisomerization process in which a new type of dual function catalysts is used for the production of jet fuel from paraffinic middle distillates has been suggested. The new catalyst which is composed of nonplatinum metal components and an acidic carrier possesses high activity, good selectivity, and good durability. In the presence of this catalyst and under medium hydrogen pressure, hydrogen consumed is 0.3—0.5% and the liquid product yield is 95—97%.A 67% yield of jet fuel can be obtained from the...

A new hydroisomerization process in which a new type of dual function catalysts is used for the production of jet fuel from paraffinic middle distillates has been suggested. The new catalyst which is composed of nonplatinum metal components and an acidic carrier possesses high activity, good selectivity, and good durability. In the presence of this catalyst and under medium hydrogen pressure, hydrogen consumed is 0.3—0.5% and the liquid product yield is 95—97%.A 67% yield of jet fuel can be obtained from the hydroisomerization of a middle cut feedstock in single-pass over the new catalyst at 420℃, hydrogen pressure 40 atm., space velocity 0.70, and volume ratio of hydrogen to oil 1000:1. Its chief physicochemical properties are as follows: specific gravity 0.783 (d_4~(20)), freezing point —64℃, heat of combustion (net) 10320 kcal/kg, and an aromatic content about 16%.

The Co-carbonization of Shah Dong Yu-cun gas coal with coal tar pitch(CTP), oxidizing petroleun asphalt(OPA) and petroleun coke(PC) were researched. CTP and OPA were used as binder while PC as modified inert additives. Influence of the type of binder(and modified inert additives), blending content, median treatment temperature and soaking time at final temperature on the properties of cokes from co-carbonization. The results indicate that the isotropic optical texture of cokes from Yu-cun coal can be modified by CTP addition to fine mosaic texture. With increasing binder content in the blend, the amount of optically anisotropic areas in cokes and the microstrength of cokes are increased as well as the chemical reactivity of cokes is decreased. Soak period of 30 rain in 420-470℃ would increase the amount of optically anisotropic texture. Soaking resonable time at final temperature would increase the microstrength of cokes.

研究了山东禹村气煤和焦油沥青(CTP)、氧化石油沥青(OPA)及石油焦的共碳化。CTP和OPA作为粘结剂,石油焦作为改质惰性添加物。研究了粘结剂(及改质惰性添加物)类型、配量、中间处理温度和终温停留时间对共碳化焦炭性质的影响。结果表明,禹村焦的各向同性光学结构通过焦油沥青能改质为细粒镶嵌结构。随配合煤中粘结剂数量增加,焦炭中光学各向异性面和焦炭显微强度增加,焦炭的化学活性降低,420—470℃下停留30分可以增加光学各向异性结构的数量,终温停留适当时间可以增加焦炭的显微强度。

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...

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。
