Patent number: 8260464Abstract: A control technique for use in a fuel processor is disclosed. In one aspect, a control system includes a subsystem manager controller the operation of a respective physical subsystem for each of a plurality of physical subsystems in the fuel processor. The subsystem managers take their direction from a master control manager. In a second aspect, the subsystem managers collectively form a layer operating in conjunction with a second layer capable of interfacing the subsystem managers to their respective physical subsystems, a third layer capable of interfacing the subsystem managers with the second layer. In a third aspect, master control manager manages the operation of each physical subsystem through a respective subsystem manager, directs state transitions of the subsystem managers, and routs interaction between the subsystem managers from the master control manager.Type: GrantFiled: November 14, 2007Date of Patent: September 4, 2012Assignee: Texaco Inc.Inventors: Vesna R. Mirkovic, W. Spencer Wheat, Hugh N. To, Dennis J. Benedetto

Publication number: 20110247724Abstract: In order to increase the hydrogen utilization rate of the cascade storage system, after dispensing gaseous hydrogen to a hydrogen vehicle, gaseous hydrogen is transferred via a compressor from at least one storage vessel at a lower pressure to at least one storage vessel at a higher, dispensable pressure. The methods of the present invention economically and efficiently increase the utilization rate of gaseous hydrogen stored in a cascade storage system by managing the storage of gaseous hydrogen and increasing the utilization rate of gaseous hydrogen stored in a cascade storage system.Type: ApplicationFiled: March 23, 2011Publication date: October 13, 2011Applicant: Texaco Inc.Inventors: Farshad Alexander Bavarian, Dennis J. Benedetto, John Michael Brady, Daniel Glenn Casey, Dean Alan Kenefake, Charles Franklin Perdue, JR., Hongqiao Bruce Sun

Patent number: 6759156Abstract: An operational cycle for a fuel processor capable of reforming a fuel, the operational cycle is disclosed. The operational cycle includes: an off state; a manager check state entered into from the off state, and in which the operational readiness of the fuel processor is checked; a preheat state entered into from the manager check state, and in which the fuel processor preheats gases, including the fuel, for mixing into a process feed stream; a startup state entered into from the preheat state, and in which the fuel processor begins operating under start-up conditions; a run state entered into from the startup state, and in which the fuel processor reforms the process feed stream into a reformate under steady-state conditions; and a shutdown state entered into any one of the manager check state, preheat state, startup state, and run state. The operational cycle may be employed in a fuel processor for a fuel cell or a fuel cell power plant.Type: GrantFiled: April 4, 2003Date of Patent: July 6, 2004Assignee: Texaco Inc.Inventors: W.
