This study considers the influence of stream treatment on the activity if iron-pillared montmorillonite in vacuum gas oil cracking and the change in its physical-chemical characteristics. Stream treatment was demonstrated to result in a decreased specific surface area and iron and silicon content, as well as in the strengthening of the catalysts. After stream treatment, gasoline and gas yield is reduced and raw material conversion decreases. Before stream treatment, the proportion of aromatic hydrocarbons in cracking gasoline does not exceed 24.1%, while the isoparaffin content is 24,5%. After stream treatment, the aromatization of gasoline increases and the content of paraffin-naphthenic hydrocarbons decreases. The main component of cracking gases is butane-butylene fraction with a content equal to about 40% before stream treatment, which remains unchanged after processing.

蒸汽处理对真空瓦斯油裂解中铁柱蒙脱石活性的影响

本研究考虑了蒸汽处理对铁柱撑蒙脱石减压瓦斯油裂解活性的影响及其理化特性的变化。流处理被证明导致比表面积和铁和硅含量的降低,以及催化剂的强化。物流处理后,汽油和气体收率降低,原料转化率降低。物流处理前,裂解汽油中芳烃的比例不超过24.1%,而异链烷烃的含量为24.5%。物流处理后,汽油的芳构化增加,链烷烃含量降低。裂解气的主要成分是丁烷-丁烯馏分,在物流处理前含量约为40%,
