摘要： The invention provides a method of increasing the mesopore volume of a porous activated carbon, comprising coating a porous activated carbon with a metal oxide or metal oxide precursor to form a treated activated carbon; and calcining the treated activated carbon, in a dry atmosphere, for a time and at a temperature sufficient to increase the mesopore volume of the treated activated carbon. The invention also provides an activated carbon having a total mesopore volume of at least about 0.10 cc/g and less than about 0.25 cc/g, and a percentage of mesopore volume per total pore volume of at least about 15% and less than about 35%. Activated carbon modified according to the invention, cigarette filters incorporating such activated carbon, and smoking articles made with such filters are included in the invention.
摘要翻译：本发明提供一种增加多孔活性炭的介孔体积的方法，包括用金属氧化物或金属氧化物前体涂覆多孔活性炭以形成经处理的活性炭; 并在干燥气氛中煅烧经处理的活性炭一段时间和足以增加经处理的活性炭的中孔体积的温度。本发明还提供了具有至少约0.10cc / g且小于约0.25cc / g的总中孔体积的活性炭，并且每个总孔体积的中孔体积百分比为至少约15％且小于约35 ％。根据本发明改性的活性炭，包含这种活性炭的香烟过滤嘴以及用这种过滤器制成的吸烟制品包括在本发明中。
