The vapor pressure-temperature relationship of Fushun shale oil fractions is found to be quite similar to that of the petroleum or pure hydrocarbons, and the empirical formula log P=A—B/(T-43) can be applied to shale oil. The values of A and B of the above formula and also the conversion chart are given in this work. The boiling points measured at certain pressure are compared with values computed for this pressure from the corresponding boiling points at other pressures by the conversion chart,...

The vapor pressure-temperature relationship of Fushun shale oil fractions is found to be quite similar to that of the petroleum or pure hydrocarbons, and the empirical formula log P=A—B/(T-43) can be applied to shale oil. The values of A and B of the above formula and also the conversion chart are given in this work. The boiling points measured at certain pressure are compared with values computed for this pressure from the corresponding boiling points at other pressures by the conversion chart, it is seen that the maximum deviations are within ±2℃.

The aromatization of a C_8-C_9 fraction (105—155℃)of Fischer-Tropsch naphtha over chromia-alumina catalyst at various temperatures and space velocities has been investigated. At 500℃ and LHSV 0.43, the once-through total conversion is 84%, and the yield of aromatics is about 60% (based on feed stock). Under these conditions, about 37% (based on feed stock) of xytene-ethylbenzene fraction is obtained, which consists mainly of ethylbenzene and o-xylene. On regeneration, over 93% of coke-deposition can be...

The aromatization of a C_8-C_9 fraction (105—155℃)of Fischer-Tropsch naphtha over chromia-alumina catalyst at various temperatures and space velocities has been investigated. At 500℃ and LHSV 0.43, the once-through total conversion is 84%, and the yield of aromatics is about 60% (based on feed stock). Under these conditions, about 37% (based on feed stock) of xytene-ethylbenzene fraction is obtained, which consists mainly of ethylbenzene and o-xylene. On regeneration, over 93% of coke-deposition can be easily burned off, but a small amount of coke remains unburned, and shows no significant effect on the activity of catalyst. The C_8-C_9 fraction used contains 13% of olefins. Removal of the olefins from it decreases the coke formation rate, and increases the aromatic content in the liquid product.

Some kinds of Chinese coal have been hydrogenated in the autoclave for catalyst studies.Under the condition:temperature 450°,initial hydrogen pres- sure 100 atm./20°,and reaction time 1 hr.,the conversion of Shenli coal of Fushun reaches or exceeds 95%,when SnC_2O_4+NH_4Cl,SnCl_2,tin ore+NH_4Cl, ZnCl_2,(NH_4)_2MoO_4,FeS,or sulfurized bogiron ore is used as catalyst. A time-saving“microautoclave”technique is developed and is recommended for the preliminary study of coal hydrogenation. In the range of temperature 400—450℃ and initial hydrogen pressure 50—100 arm.,the order of hydrogenation activity of the three series of catalysts studied is:tin>molybdenum>iron;for the conversion of asphaltene,the activity of tinhalide catalyst is also the highest. As shown in this investigation,the Shenli coal of Fushun is well amenable to hydrogenation,and its use in the production of aromatic compounds and liquid fuel is very prospective.
