摘要 为解决重质芳烃难以处理的问题,开发了一种C_(10)^(+)重质芳烃轻质化工艺。以某炼厂生产的C_(10)^(+)重质芳烃和新鲜氢气为原料,在工业侧线装置上进行性能评价。在优化操作条件下,C_(10)^(+)重质芳烃经轻质化工艺流程处理后可转化为混合芳烃和C_(7)轻烃及以下组分,其中混合芳烃质量约占产物质量的57%,混合芳烃中以C_(8)—C_(10)芳烃为主,且主要为单环芳烃,可作为目前歧化与烷基转移技术的原料,用于生产对二甲苯。通过C_(10)^(+)重质芳烃轻质化工艺可以将附加值较低的重质芳烃转化成高附加值的轻质芳烃,产生较好的经济效益。 In order to solve the problem of difficult treatment of heavy aromatics,a kind of process for converting C_(10)^(+) heavy aromatics into light aromatics was developed.The performance was evaluated on the industrial side line unit,using C_(10)^(+) heavy aromatics and fresh hydrogen produced by a refinery as raw materials.Under the optimized operating conditions,C_(10)^(+) heavy aromatics can be transformed into mixed aromatics,C_(7) light hydrocarbons and the lighter components after being treated by the lightening process,in which the mixed aromatics account for about 57%(mass fraction)of the product composition.The mixed aromatics are mainly C_(8)-C_(10) aromatics and mainly monocyclic aromatics,which can be used as raw materials for the current disproportionation and alkyl transfer technology to produce p-xylene.Through C_(10)^(+) heavy aromatics lightening process,heavy aromatics with low added value can be transformed into light aromatics with high added value,resulting in better economic benefits.
