Relation of the different acid density and different time treatment with thedecolorant power,surface area, SiO_2/Al_2O_3 of active bentonite were studied.The resultsof experiments show that controlled lower acid density and long time of treatment isimportant.The decolorant power of active bentonite can reach 330,when treatmentcondition is w_(H_2SO_4)=0.2 and 8 hours.

本项研究对不同酸度、不同时间条件下处理的膨润土进行了脱色力、比表面积、活性膨润土中硅铝比分析及扫描电镜测试,由此,总结出控制获得高效活性膨润土的最佳条件应是使比表面积尽可能大,硅铝比尽量高。在适当控制酸度情况下,可以通过调整活化处理时间来取得较理想的性能。

The prospect for the application of activated bentonite is very broad in the fields of petrochemical industry and environmental protection. The natural bentonite was purified and then activated by H_2SO_4 solution. The precipitates were washed with water and centrifuged; and therefore the activated bentonite was obtained. The properties of synthesized activated bentonite were characterized, and the influences of H_2SO_4 solution concentration, reactive time, reactive temperature and different bentonites on H-CEC...

The prospect for the application of activated bentonite is very broad in the fields of petrochemical industry and environmental protection. The natural bentonite was purified and then activated by H_2SO_4 solution. The precipitates were washed with water and centrifuged; and therefore the activated bentonite was obtained. The properties of synthesized activated bentonite were characterized, and the influences of H_2SO_4 solution concentration, reactive time, reactive temperature and different bentonites on H-CEC and free acid were studied. The optimal conditions were put forward on the basis of above investigations. The results show that the materials have high H-CEC and low free acid.

活性膨润土在石油化工、环境保护等领域有十分广阔的应用前景。通过采用天然膨润土为原料,提纯后用硫酸溶液进行活化,反应产物经水洗、分离后得到活性膨润土,并且对活化产物进行性能测试,并初步研究了硫酸的质量分数、活化时间、活化温度和不同膨润土原料对氢转换量和游离酸量的影响,并提出了制备活性膨润土的最佳的反应条件。测试结果表明产物是氢转换量高,游离酸低的高活性膨润土

The influence of the ratio of liquor to solid,acidity, temperature and reaction time on product quality during the producing of acid active bentonite was investigated. The optimal process conditions was summed up and some methods of improving the acid active bentonite quality was proposed. The ratio of liquor to solid from 1.3 to 1.6,acidity from 15 percent to 25 percent,temperature from 95℃ to 105℃, 4 h of response time , thus the decolourization strength can be up to about 169, the activation degree more than...
