摘要
为探讨超声波辐射溶胀在煤炭直接液化过程中的积极作用,以吡啶为溶胀剂对神华煤进行了超声波辐射条件下的溶剂溶胀处理,通过对溶胀过程中不同溶胀时间煤样的溶胀度与质量损失情况测定以及超声波辐射溶胀煤与自然溶胀煤的液化实验比较,发现超声辐射有助于煤的溶胀作用,煤液化转化率提高了3%~4%.实验表明,超声溶胀能够进一步提高煤催化加氢直接液化的反应性能.
Shenhua coal was swelled in an ultrasonic generator with pyridine as the swelling agent.In order to investigate the effects of ultrasound swelling on coal liquefaction,the loss of coal and swelling rate were determined and the IR spectra was analyzed.The ultrasonic swelling of coal can enhance the reaction of direct liquefaction of catalytic hydrogenation further by contrasting the liquefaction of coal swelled by ultrasonic wave radiation and the naturally swelled coal.The liquefaction conversion rate of Shenhua coal increases 3%-4% after the treatment of ultrasound irradiation.
