磷酸活化竹节制备醋酸乙烯载体活性炭的研究
Preparation of Bamboo Knot Activated Carbon as Vinyl Acetate Catalyst Carrier by Phosphoric Acid Activation
摘要
Abstract
Bamboo knot was used to prepare activated carbon as vinyl acetate catalyst carrier by phosphoric acid activation. The result showed that the adsorption value of acetate,BET,microporous volume increased with rising temperature (325 -400℃) ,impregnate ratio (0. 60-0. 75) and holding time ( 3 -6 h),but the adsorption of zinc acetate showed the opposite trend. N2-adsorption isotherm showed that the possessed activated carbon developed microporous and macroporous structure. Under the optimized condition,i. e. activation temperature 350 ℃ ,holding time 5 h and impregnation ratio 0.65,the adsorption value of acetate and zinc acetate,BET,microporous volume were 527.5 mg/g,70 g/L,999.0 m /g and 0.468 cm /g,respectively.关键词
