Abstract: Methods of using a catalyst preburner upstream of a catalyst burner, such as an anode tailgas oxidizer (ATO), in fuel processing applications. The methods prepare a hydrogen containing gas mixture which can be effectively combusted in a single ATO. The catalyst preburner will convert raw fuels into a gas mixture including hydrogen. This hydrogen containing gas mixture then mixes with the required air flow and anode tailgas and off-gas from a pressure swing adsorption unit before being introduced into the catalyst burner. The methods address the start-ups needs of an ATO as well as the requirement that an ATO be able to burn both liquid and gas fuels in a single unit.

Abstract: Methods for accurately and conveniently calculating the inventory of hydrogen storage in a stationary storage vessel using the external ambient temperature and the internal pressure are disclosed in the present invention. To account for the delay in the heat transfer from the ambient air to the storage vessel and then to the hydrogen gas a first order filter can be used on the external ambient temperature. Following the application of the first order filter on the external ambient temperature, an empirical equation is used to calculate the mass of hydrogen in the stationary storage vessel.

Abstract: 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.

Abstract: Normal olefins such as n-butenes can be converted to iso olefins such as isobutylene by skeletal isomerization over catalysts of boron-beta zeolites having pore sizes of at least about 5 Angstroms and containing boron in the framework structure thereof. The boron-beta zeoliteS have sufficient acidity to catalyze the skeletal isomerization of normal olefinsto iso-olefins. The catalysts can be used to produce iso-olefins for reaction with alcohols in integrated processes to produce alkyl tertiary alkyl ethers such as MTBE.
