By using the fluidized-bed and partial oxidation technique, sawdust has been successfully pyrolysed in laboratory on an experimental apparatus. For the purpose of comparison, a fixed bed and an external heating fluidized bed have been used for parallel runs of carbonization. It has been proved by a number of runs that the tar yields as well as the rates of distillation by fluidized partial oxidation method are far much higher than those by any other method reported in current literature. Besides, the present...

By using the fluidized-bed and partial oxidation technique, sawdust has been successfully pyrolysed in laboratory on an experimental apparatus. For the purpose of comparison, a fixed bed and an external heating fluidized bed have been used for parallel runs of carbonization. It has been proved by a number of runs that the tar yields as well as the rates of distillation by fluidized partial oxidation method are far much higher than those by any other method reported in current literature. Besides, the present process has shown distinct advantages over the others in low capital cost and being simpler in processing.

在实验装置上用流化床部分氧化法成功地干镏了锯木屑。为了便于比较,还以固定床和外热式流化床进行了平行试验。一系列试验证明,用流化床部分氧化法可以获得比现行其他方法较高的焦油收率和高得多的镏出速率,而且建造容易,过程简便。试验了由木焦油镏分制得的抗氧化添加剂的添加效果。通过对延迟焦化汽油的氧化安定性试验(诱导期试验),证明所制得的添加剂具有良好的抗氧化稳定性。初步结果表明,本研究为制取抗氧化添加剂和实现锯木屑综合利用提供了有希望的途径。

In a radiation furnace, an externally heated tubefurnace, some pulverized brown coals are put into rapid pyrolysis. Considerably high yields of medium- heat-value gas,tar and char residue are obtained. The content of ethylene and propylene in the gaseous product is quite high, and the tar distillation yield, below 280℃ is substantially high, and its gasification rate is very fast. Adsorption ability of this char residue is good. Its ignition point is low, so it was found to have quite wide uses. The rapid pyrolysis...

In a radiation furnace, an externally heated tubefurnace, some pulverized brown coals are put into rapid pyrolysis. Considerably high yields of medium- heat-value gas,tar and char residue are obtained. The content of ethylene and propylene in the gaseous product is quite high, and the tar distillation yield, below 280℃ is substantially high, and its gasification rate is very fast. Adsorption ability of this char residue is good. Its ignition point is low, so it was found to have quite wide uses. The rapid pyrolysis of rich oil-shale ore yielded a gaseous product with heat value higher than 8000 kcal/nm~3, rich in ethylene and propylene. Light component in its tar is abundant and is suitable raw material for manufacturing liquid fuel. The rapid pyrolysis process using radiation-heated furnace is an effective method for upgrading the economic value of products from low grade fuel. This work has been accomplished with the joint effort made by a1l staff members of this research division.

The steel for bearing,alloy stell for moulding and the Precision parts are experimentally quenched in out-heating furnace made by ourselves. After the alloy steel (such as 9Cr18,Cr12MoV and 4Cr13) having hardening ability of air cooling is quenched into oil or water together with furnace Pipes. The hardness of sampies is equivallent to that of salt bath or a little higher than that of 1- 2HRC.When the other kinds of steel are quenched, as the cooling speed is not enough,they can't harden,so the internal cooling should be adopted by adding nitrogen at the same time,or directly put the workpiece into oil or water,thus the high hardness can be obtained. After vacuum quenching,the finish of workpiece is good,there is not decarburization on the surfaces of workpiece, the deformation of workpiece is small.and the higher stress is formed on the metal surfaces.The effect is well when the apparatus is applied to vacuum heat treatment of small precision parts.

用自制的外热式真空炉对轴承铜和合金工模具钢的试样进行了真空淬火试验,并用于精密零件的热处理,结果得出,具有空冷硬化能力的高合金钢(如9 Cr18、Cr12 Mov和4Cr13)工件随同炉管一起淬入油或水中冷却,试样的硬度和盐浴加热淬火者相当或略高1~2 HRC。其它钢种淬火时由于冷却速度不够,不能淬硬,必须同时通入氮气进行内冷却,或者破坏真空将工件直接淬入水或油中冷却才能得到高硬度。真空淬火工件的表面光洁,无氧化脱碳现象,零件变形小,而且在金属表面形成较高的残余压应力。该装置应用于小型精密零件的真空热处理,效果良好。
