Abstract:
A hydrocracking zone for the selective production of either a naphtha product stream or a middle distillate stream from a hydrocarbonaceous feedstock utilizing a fixed catalyst and varying the ammonia concentration level introduced to the hydrocracking zone. The ammonia can be obtained by the reaction of nitrogen in the hydrocarbonaceous feedstock in a hydrotreating reactor, or from an external ammonia source, where the ammonia concentration is controlled by a stripping zone which allows an ammonia concentration in the range of about 0 to about 50 wppm to be introduced into the hydrocracking zone to yield a naphtha stream and an ammonia concentration in the range of about 20 to about 200 wppm to be introduced into the hydrocracking zone to yield a middle distillate stream.
