    • The process involves the use of specifically selected coke precursor compounds from the front end of oil distillate fractions that contain C11 to C14 hydrocarbons and their use as additives in the processing of naphtha in a catalytic reformer. The C11 to C14 compounds additives enhance coke make in continuous catalytic regeneration (CCR) reformers to levels higher than those which are usually produced in low coke naphtha reforming operations. With the increase of ethanol blending in gasoline and low reformate octane severity operations, reformers do not produce the necessary amount of coke to permit sustaining steady state white burn operations.
    • 该方法包括使用来自含有C 11至C 14烃的油馏分馏分的前端的特定选择的焦炭前体化合物及其作为催化重整器中石脑油加工中的添加剂的用途。 C11至C14化合物添加剂将连续催化再生(CCR)重整器中的焦炭提高到通常在低焦碳石脑油重整操作中生产的水平。 随着汽油中乙醇混合的增加和重整油辛烷值的降低,改性剂不会产生必要量的焦炭,以维持稳态白烧操作。
