HANDBOOK OF PETROLEUM REFINING PROCESSES 2/E
With worldwide petroleum refining capacity expected to continue its expansion well into the 21st Century, here is a timely and thorough revision of the definitive handbook on the licensable technologies for producing environmentally acceptable fuels and petrochemical intermediaries.
A global compendium of refining technologies, this handbook has been prepared by UOP, Chevron, Exxon, Foster Wheeler, MW Kellogg, and Stone and Webster, six major technology licensors. In addition, many of the technologies presented here were co-developed with firms around the world, including such organizations as British Petroleum, Insitut Francais du Petrole, Catalyst Chemical Industries Co., Instituto Mexicano del Petroleo (IMP), and Sinopac International.

Hi TD2K,
1)For Naphtha Reformer:
Catalytic Naphtha Reforming , edited by Antoinne & Pereira(This one is better than the one by Donald Little)

2) For Hydrogen and associated like shift Reactions : 'Catalyst Handbook' by Martyn Twigg, This book also has ammonia , etc.

3) Distillation Operation and Distillation Design by Kister (these are two books)

4) For hydrotreaters and hydrocrackers : If you can refer to UOP technology manual, if you have UOP plants, they are quite good.
And I feel one recommended by 25362 is good for hydrocracker.

Regards,
