            研究了从玉门轻质润滑油中用硅胶、氧化铝、活性白土和活性炭作吸附剂的吸附和热扩散分离低凝固点油的方法.用硅胶、氧化铝、活性白土吸附分离时,所得大部分分离油的凝固点都高于原料油,仅分离出一少部分凝固点略低于原料油的油.活性炭是一种非常有效的分离低凝固点润滑油的吸附剂,其中以抚顺活性炭为最好.用抚顺活性炭吸附分离时,得到了40%凝固点低于-35°(原料油的凝固点)的馏分,最低凝固点可达-63°.热扩散也是一个有效分离低凝固点润滑油的方法,但分离油最低凝固点只有-55°.

            进行了撫順残植煤的化学—工艺性质的評述。研究了残植煤各岩相組分(鏡煤类物质、孢子残体、树脂体)的一次焦油的組成;特别详细地采用紅外光譜和色层分离方法研究了树脂体焦油。撫順残植煤是很好的低溫干餾的原料。在热载体並流、多次往复循环实驗炉中进行的低溫干餾結果表明,可从残植煤得到较高收率的轻质化学产品和大量宝貴的煤气。采用色层分离法系統研究了撫順残植煤焦油的中性油的族組成。首次研究了低溫焦油中丙酮可溶性酚的組成。結果表明,在氮气流中进行甲基化,用色层法分离酚甲醚,並随后用化学、物理方法鑑定各組分,可以认为是比較好的一种研究重餾分混合酚的方法。

         A new process for producing roofing asphalt from petroleum residua by steam cracking and condensation has been studied in the laboratory. Three different stocks, i. e. Shengli and Renqiu vacuum residua and PDA asphalt of Renqiu vacuum residue,were used.Experiments were carried out in a 5 liter reactor at temperature 400 to 415℃ under atmospheric pressure and in the presence of superheated steam, while the reaction time was selected according to the softening point of the asphalt. Besides the roofing asphalt...
            在实验室中研究了一种从石油残渣油制取建筑沥青的新工艺——水蒸汽裂解缩合。使用了任丘减压渣油、任丘减压渣油的丙烷脱油沥青和胜利减压渣油三种不同原料。实验是在5升的反应器中,在过热水蒸汽存在下,反应温度为400~415℃、常压条件下进行,反应时间则根据产品沥青的软化点来选择。该过程除可得到规格要求的建筑沥青外,还可以得到一定数量的轻质馏出油,催化裂化原料和少量燃料气。各产品的产率随原料和反应条件变化。与氧化沥青过程相比,本过程另一个突出的优点是不排出有害气体,因而可以显著地减少对大气的污染。
