用煤矸石制取白炭黑的研究

研究了用煤矸石制取白炭黑的可行性。将煤矸石在一定温度下活化，并破碎到一定细度后，先用酸溶出氧化铝，再通过碱浸，用常压法制取水玻璃。然后以水玻璃为原料，用酸性硅溶胶两步法制取白炭黑。研究了活化温度、破碎粒度、反应温度、ｐＨ值、酸性硅溶胶的稳定性以及陈化条件等因素对制取过程的影响，确定了制取工艺，找出了最佳操作条件。并对白炭黑的改性进行了初步研究，以进一步提高其性能。

本文研究了用煤矸石制取水玻璃的可行性，利用正交试验，研究了焙烧温度、焙烧时间、反应温度、ＮａＯＨ浓度、渣样粒度等因素对制取过程的影响，确定了最佳操作条件。

Research on a New Technique of Producing Rapid-Hardening CementContaining Coal Gangue

After five years research, a totally new technology for producing a rapid-hardening cement containing bigh content of coal gangue is proposed’ In the technology, a specially designed rotary kiln is used as the calciulng equipmeut, whose structure is more like a conventional clinker cooler than a conventional rotary kiln. A fluidized bed furnace fueled by coal gangue is designed as its heater. With this technology, the quality of the cement yielded can be guaranteed; besides, no high grade coal is needed,no wastes are produced; furthermore, the investment is greatly lowered as compared with a traditional one. So it is a new viable method for disposing coal gangue’
