Abstract: An apparatus and method for the preferential oxidation of carbon monoxide in a hydrogen-rich fluid. The apparatus utilizes one or more reactors that are dimensioned to optimize the exothermic oxidation reaction and the transfer of heat to and from the catalyst bed. A reactor of the apparatus has an elongated cylindrical catalyst bed and heat transfer means adjacent the catalyst bed. The heat transfer means is suitable for pre-heating the catalyst bed during start-up operations and for removing the heat from the catalyst bed during the oxidation reaction. One or more reactors of different dimensions may be utilized depending upon the pressure of the hydrogen-rich fluid to be directed into the apparatus and the pressure requirements for the carbon monoxide-depleted fluid exiting the apparatus. For instance, in low pressure operations where it may be desirable to minimize the pressure drop across the apparatus, two or more reactors having relatively smaller dimensions can be utilized. In higher pressure operations where pressure drop across the preferential oxidation apparatus is of less concern, a single reactor having larger dimensions may be utilized. The relatively narrow dimension of the catalyst bed coupled with the relatively large surface are used for heat transfer provides for more uniform temperatures within the catalyst bed and improved temperature control of the bed.

Abstract: An apparatus and method for producing hydrogen. The apparatus includes a fuel processor, a purification unit and a system controller. The controller determines a calculated flow of reformate from the fuel processor and operates the purification unit based on the calculated flow. The calculated flow is derived from a process model of the fuel processor and known feed(s) to the fuel processor. The calculated flow of reformate is used to control the flow of reformate to adsorbent beds within the purification unit and can be used to control other materials flows within the apparatus. Means for reducing fluctuations in the pressure and/or flow rate of reformate flowing from the fuel processor to the purification unit are also disclosed. The purity of the hydrogen produced can be maintained by adjusting the operation of the purification unit in response to changes in reformate composition, pressure and/or flow rate.

Abstract: A specialized mounting arrangement for an accessory such as an engine driven air conditioner compressor to an engine is utilized featuring a pair of press fitted bushings in a pair of arms of the mount and a single bolt extending therethrough. The arms of the mount assembly are constructed so that they straddle portions of an anchor member attached to the engine. A connector bolt is inserted through one bushing in one arm of the mount and then thorough a passage in the anchor member, and next into engagement with internal threads carried by the other bushing which his carried by the other arm of the mount. Rotation of the bolt moves the bushings toward one another and against the ends of the anchor member to clamp the anchor and thus the accessory therebetween. This clamping construction permits the accessory and mount to be adjusted axially relative to the bold so the accessory can be aligned relative to the engine drive arrangement before the accessory is finally affixed to the engine in a non-adjusting fashion.

Abstract: A method for operating a combustor having a catalyst bed. The method includes the steps of directing a flow of air through a catalyst bed, providing heat to the catalyst bed, sensing the temperature in an upstream portion of the catalyst bed to provide an upstream temperature, directing a flow of a fuel through the catalyst bed when the upstream temperature reaches a light-off temperature to produce a combustion reaction, increasing the flow of the fuel until the flow of air and the flow of fuel have a selected air to fuel ratio, and controlling the combustion reaction within the catalyst bed by adjusting the flow of air and the flow of fuel while maintaining the selected air to fuel ratio. The method can include sensing temperatures within the catalyst bed and controlling the combustion reaction in response to the sensed temperatures. The heat provided to the catalyst bed can also be adjusted in response to the sensed temperatures. The methods can further include exchanging heat between heated combustion products and one or more reforming reactants.
