Disposal of Waste Plastics With Traditional Coking Process

A new technology for treating waste plastics （WP） by traditional coking process was introduced. With a thermo-balance and a 10 g atmospheric fixed bed reactor, the thermo-gravimetric behavior and product were studied during co-coking of WP with blended coal. And then, using a coke-oven with capacity of 200 kg, the characteristics of products were assessed. The results showed that there is an overlapping temperature range （200-550℃ ） of decomposition between WP and blended coal, and the pyrolysis synergism index η and synergism strength β proposed could evaluate the synergism between them. 1% of added WP results in the maximum synergism in all series experiments. The increase of added WP decreases the synergism. Tar yield in co-coking is increased with the decrease of water yield for synergism. Moreover, it was also found that the quality indexes of coke, such as M10, M40, CRI and CSR, are degraded with the increase of WP until 4%, though the quality of tar and gas is optimized for WP addition.     

焦油渣回收利用的研究与应用

炼焦生产过程中,生产的高温焦炉煤气在集气管或初冷器冷却的条件下，高沸点的有机化合物被冷凝形成煤焦油，与此同时，煤气中夹带的煤粉、半焦等也混杂在煤焦油中,形成大小不等的团块,这些团块称为焦油渣。焦油渣的数量与炼焦煤料的水分、粉碎程度及装煤操作有关,一般焦油渣占炼焦干煤的0.15-0.20％。

废塑料配煤炼焦的小焦炉试验

废塑料经分类、筛选和制粒后，用小焦炉进行配煤炼焦试验，结果表明，对焦炭强度的影响不大，还可增加炼焦化学产品的产率，但废塑料的配比宜控制在2％以下。     

间接原子吸收光谱法测定自来水及焦化厂废水中氯

氯的共振吸收线为138.0nm,位于真空紫外区,不能用原子吸收光谱法进行直接测定,但利用其与Ag~+可生成难溶AgCl沉淀的性质,通过测定已反应的或未反应的银量,可间接测定氯。血浆、植物汁液、酒等多种物质中氯的测定已有报道。我们对本所自来水及山西某焦化厂废水中的氯
