摘要
通过试验 ,建立了测定催化裂化用渣油中微量金属元素含量的方法。用干法灰化法处理样品 ,选择灰化温度为500℃ ,灰化时间为7h ,用盐酸溶解灰分 ,在水相中采用火焰原子吸收光谱法 。
The method for determing the contents of micro metal elements in residuum used in catalytic cracking was established through the tests.The contents of metal elements could be precisely determined by treating sample with dry ashing method at 500 ℃ for 7 h dissolving ash with chlorhydric acid,and using flame atomic absorption spectrometry in aqueous phase.
