采用不同含水量的氧化铝为固定相对沥青组分分离的结果进行考察。在其他条件完全相同的情况下,随加水量的增加氧化铝的吸附活性与分离选择性下降。考察了四种有代表性的渣油与沥青的各组分收率与柱残留量随氧化铝含水量不同的变化规律。
Using different water content of alumina as a fixed phase relative to the separation of asphalt components were investigated. Under the same conditions, the adsorption activity and separation selectivity of alumina decreased with the increase of water addition. The variation of the yield of the four representative residues and the residue of the column with the alumina moisture content were investigated.
