【Abstract】 Amorphous granular activated carbon was prepared with steam activation from hickory nuts according to orthogonal tests. The average yield of charring was 39.88%, the yield of activation was 30.4%～41.5% at the optimum conditions. Some samples could meet the requirement of carrier activated carbon of catalysts. This may be as a usage of hickory nuts.更多还原
