This task uses liquid sulfur dioxide to extract aromatics from another material in the Edeleanu process. MCM-41, a mesoporous silicate material, is principally used as an alternative to certain catalysts for one stage of this task. Coker units are involved in this task, where mercaptan oxidation is a form of sweetening. Boiling at a lower air pressure removes the flasher tops from the resid, or bottoms, left behind by this process. Reformers, alkylation (-5[1])units, and (*) hydrocrackers (10[1])are found in facilities for performing this task, which also uses fluid catalytic cracking. This task uses fractional distillation to create products such as naphtha and paraffin wax. For 10 points, name this task that produces kerosene, diesel, gasoline, (10[1])and similar products. ■END■ (10[1])
