为了降低焦油加工时的酸硷耗量、简化加工过程,进行了酚钠抽提方案之研究。 试验中考察了硷液浓度及焦油馏份中的酚类含量对抽提效果之影响;逆流抽提时之最宜硷用量;饱和酚钠液稀释以析出溶解的酚类时所需之水量;以及抽余油及粗酚的物理化学性质等。 试验结果表明:酚钠抽提法不但耗硷量甚少(对每百公斤酚类只需苛性钠10—15公斤,而一般硷洗法则需用40—45公斤)。而且抽余油不需经酸洗或氧化精制等过程,即可做轻柴油使用,其氧化安定性较好。此外酚钠抽提有显著的脱硫及脱氮作用。 抽余油之发动机试验证明:做为轻柴油其使用性能在任何方面均不逊于其他简易加工方法所制得之产品。

An oil sprays made up of DDVP as the main pesticide, 1,2-dichlorobenzene as an auxiliary solvent and diesel oil as a diluent is a new processing preparation. Field tests showed that the oil spray could be used for ULV aerial application, ULV area application and area smoke spraying. Some of the advantages of the oil sprays are : high-speed in killing with poison, good effectiveness, small dosage, easy operation, wide source of raw materials, handy process, low cost and so on.

This paper presents, at first, part of the data on the use of diesel-powered trackless mining equipment in 36 Swedish hardrock underground mines and the threshold limit values of diesel emissions in the underground mine atmosphere, drawn up by the Swedish National Board of Occupational safety and Health. It mentions the large amount of scientific research which has been carried out and is still being studied by designers, manufacturers, mines and research arganizations in order to satisfy these standards. The aims, tasks, fundamental equipment and research methods of diesel exhaust cleaning in the diesel engine laboratory of the University of Lulea are illustrated. It is pointed out that research on purifying diesel exhaust gases should be speeded up for solving the serious mine ventilation problem caused by the use of diesel-powered equipment. The paper concludes that efforts should be made to provide new facilities for efficient ventilation and to develop more modernized trackless mining equipment by increasing research work in the field of automatic ventilation control as well as the design and manufacture of new L H D machines, either diesel-electric-powered or electric-powered with trailing cables. Additional papers in this field of research will follow

文章首先扼要地介绍了瑞典全国三十六个地下金属矿山使用柴油无轨设备的部分统计资料,以及瑞典政府职业安全与健康局关于井下大气中柴油机废气的临界极限标准。指出,为达到这一标准,采掘机械设计制造部门、矿山、科研单位,已经并正在进行大量的研究工作。接着,比较系统地介绍了瑞典律勒欧大学柴油机废气净化实验室的研究任务、目的、基本设备和试验方法。最后,联系柴油无轨设备大量使用所引起的严重的通风问题指出,必须进一步大力开展柴油机废气净化的研究工作。并配合自动通风控制,研究柴油-电力驱动或电缆蒎筒式装运卸机等,将无轨开采技术装备推进到新阶段。
