山核桃壳活性炭对煤气洗涤水的吸附净化
Purification of gas washing water from underground coal gasification by activated carbon prepared from pecan shell
摘要
Abstract
Activated carbon with pecan shell as raw material,after phosphate impregnation, carbonization and activation,can be produced. The surface morphology and pore size distribution of the activated carbons were characterized by SEM and nitrogen adsorption measurement.Furthermore, gas washing water from model test of underground coal gasification was purified by pecan shell activated carbon. The removal effects of volatile phenol,TOC、COD、ammonia and some elements were investigated. Results showed that the specific surface area and total pore volume of prepared activated carbon can be 2959m2/g and 2.223cm3/g. It incorporate both micro-pore and meso-pore with pore size range of 1—6nm. The removal rates of volatile phenol,TOC and COD values by pecan shell activated carbon after 45h can be 99.75%,88.33% and 65.73%,respectively. The removal rates of ammonia and trace elements after adsorption for 15 h reaches 80.71% and higher than 99%.关键词
