The present invention discloses a fluidized bed system for the single step reforming technology for the production of hydrogen. Single step reforming combines the steam methane reforming, water gas shift, and carbon dioxide removal in a single step process of hydrogen generation. In the present invention, to address the heat transfer and the replenishment issues associated with single step reforming, the sorbent particles are fluidized. This fluidization allows the sorbent particles to be regenerated and consequently allows the optimal operating conditions for single step reforming to be maintained.

Fluidized bed system for single step reforming for the production of hydrogen

The present invention discloses a system for biomass treatment which addresses the need to find economical solutions to transport biomass. In the present invention, small, distributed gasifiers convert the biomass into synthesis gas ('syngas'). The syngas is then transported via a pipeline network to a central fuel production facility.

Relates to a process and apparatus that improves the hydrogen production efficiency for small scale hydrogen production. According to one aspect, the process provides heat exchangers that are thermally integrated with the reaction steps such that heat generated by exothermic reactions, combustion and water gas shift, are arranged closely to the endothermic reaction, steam reformation, and heat sinks, cool natural gas, water and air, to minimize heat loss and maximize heat recovery. Effectively, this thermally integrated process eliminates excess piping throughout, reducing initial capital cost.

The present invention discloses a heat transfer unit which integrates a boiler and a gas preheater for steam generation and gas preheating. In one embodiment, the heat transfer unit of the present invention may be used in fuel processing applications. In this embodiment, the heat transfer unit may be located downstream of a combustor such as an anode tailgas oxidizer.

The present invention discloses a hybrid combustor, such as an anode tailgas oxidizer (ATO), for fuel processing applications which combines both flame and catalytic type burners. The hybrid combustor of the present invention combines the advantages of both flame and catalytic type burners. The flame burner component of the hybrid combustor is used during start-up for the preheating of the catalytic burner component. As soon as the catalytic burner bed is preheated or lit off, the flame burner will be shut off. Optionally, the hybrid combustor may also include an integrated heat recovery unit located downstream of the catalytic burner for steam generation and for the preheating of the feed for a reformer, such as an autothermal reformer.
