ABSTRACT:
A large difficult to process hydrocracking feed stream may be processed at lower overall pressure and therefore in a unit of reduced capital cost by first dividing the feed stream into a light fraction and a smaller heavy fraction and then processing these fractions in separate reactors. The heavy fraction will normally contain the more difficult to process species and is processed in a once through reaction zone. The light fraction is processed in a higher conversion reaction zone which also receives the recycle stream produced in the product fractionation/recovery zone. The effluents of the two reaction zones may be charged into a common separator or into different separators to reduce ammonia levels in the recycle reactor.
