项目摘要
We performed a basic research on the use of waste plastics aiming the reduction of carbon dioxide emission of current 10 million tons a year from the metal industry. This year, we investigated the reduction of chromium employing solid carbonaceous fuels obtained from the dechlorination of waste plastics. We examined also the production of syngas (carbon monoxide and hydrogen) from PET, which can not be converted into oil by pyrolysis. All these processes were used to investigate their effect on the carbon dioxide reduction. Mixtures of powdered dechlorinated waste plastics, chromium slag and silicon sand were used as input material. These materials were heated in an alumina boat from room temperature to the process temperature. After that, the sexivalent chromium dissolution test was carried out with hydrochloric acid as an eluent. The yield of syngas (carbon monoxide and hydrogen) obtained by steam reforming of PET in the presence of calcium hydroxide and nickel oxide was determined. The results were compared with the use of coal in order to evaluate the effect of the substitution of fossil fuels by waste plastics and the resulting carbon dioxide reduction. After heating at 1000 ℃ in oxygen atmosphere, 1.6 % of sexivalent chromium was leached out of the sample but, after heating between 600 ℃ and 1000 ℃ in helium atmosphere, just 0.5 % was leached. These results show the possibility to substitute oil coke by dechlorinated waste plastics during the chromium slag treatment. One main product of syngas obtained from PET and PC by the pyrolysis in the presence of calcium hydroxide and nickel oxide, carbon monoxide can be used as reduction agent in the production of several metals, e.g. steel. The other main product of syngas, hydrogen is an important energy source in future technologies.
我们对废塑料的利用进行了基础研究,旨在减少金属行业目前每年1000万吨的二氧化碳排放量。今年,我们研究了使用从废塑料脱氯中获得的固体碳质燃料来减少铬。我们还研究了从PET生产合成气(一氧化碳和氢气),其不能通过热解转化为油。所有这些过程都被用来研究它们对二氧化碳减排的影响。以脱氯废塑料、铬渣和硅砂的混合物为原料,研究了不同配比的脱氯废塑料的脱氯效果。将这些材料在氧化铝舟皿中从室温加热至工艺温度。之后,用盐酸作为洗脱剂进行六价铬溶解试验。测定了在氢氧化钙和氧化镍存在下PET水蒸气重整得到的合成气(一氧化碳和氢气)的产率。将结果与煤炭的使用进行比较,以评估废塑料替代化石燃料的效果以及由此产生的二氧化碳减少量。在氧气氛中1000 ℃加热后,1.6%的六价铬从样品中浸出,而在氦气氛中600 ~ 1000 ℃加热后,只有0.5%的六价铬从样品中浸出。研究结果表明,脱氯废塑料代替石油焦处理铬渣是可行的。合成气的一个主要产物是在氢氧化钙和氧化镍存在下通过热解从PET和PC获得的合成气,一氧化碳可用作几种金属(例如钢)生产中的还原剂。作为合成气的另一种主要产品,氢气是未来技术中的重要能源。
