  • Patent number: 10843162
    Abstract: Various embodiments that pertain to oxygen enrichment are described. Oxygen enrichment is shown to allow for independent control of both reformer residence time and the oxygen-to-carbon ratio during reforming. This allows for much better control over the reformer and for significant gains in reformer through-put without negative impacts to reformer performance. Additionally, the use of oxygen enriched reforming is shown to result in enhanced reformer performance, reduced degradation from catalyst poisons (carbon formation and sulfur) and enhanced fuel cell stack performance due to greatly increased hydrogen concentration in the reformate.

    Abstract: In a process for purifying a hydrogen stream, the stream is contacted with a first washing fluid in a first purification zone under conditions effective to transfer at least some water from the hydrogen stream to the first washing fluid, thereby transforming the hydrogen stream into a water-depleted hydrogen stream. At least a portion of the water-depleted hydrogen stream may then be transferred from the first purification zone to a second purification zone, where it is contacted with a second washing fluid under conditions effective to transfer at least some oxygenates from the water-depleted hydrogen stream to the second washing fluid.

  • Patent number: 8993467
    Abstract: A method of operating a continuous or semi-continuous system for a catalyst regeneration process. The system comprises a regenerator, the regenerator comprising a combustion zone and a halogenation zone. The catalyst is fed into the regenerator. A circulating regeneration gas is introduced into a regenerator circuit including oxygen, the circulating regeneration gas having a nitrogen concentration that is less than air. Oxygen from the circulating regeneration gas reacts with the coke to provide water and carbon dioxide. Water and the carbon dioxide formed in this first reaction then further react with the coke to form carbon monoxide and hydrogen.

  • Patent number: 8979953
    Abstract: An apparatus for generating hydrogen including a housing, a reservoir, and a piston is provided. The housing has a top wall, a bottom wall, and a sidewall. The top wall has vents and a protrudent column extending to the interior of the housing. At least one vent communicates with the top wall and the protrudent column and rest of the vents surround the protrudent column. The reservoir is disposed in the housing for storing a solid state reactant and divides the housing into a first chamber and a second chamber. The first chamber is located between the top wall and the reservoir. The second chamber is located between the bottom wall and the reservoir for storing a liquid reactant. The piston is disposed on the bottom wall. The piston is used to push the liquid reactant towards the reservoir to react with the solid state reactant to generate hydrogen.

  • Publication number: 20150064104
    Abstract: Disclosed is a hydrogen generator that produces hydrogen by thermal decomposition. An electric circuit including a plurality of parallel branches, each including at least one electric heating element, is arranged in a sequence. The circuit also includes a normally open switch between adjacent branches and a normally closed switch in each branch but the last to provide current to the heating elements in the sequence of the parallel branches. Each heating element provides heat to thermally decompose a portion of a reactant, open the normally closed switch in the same branch, and close the normally open switch following that branch, energizing and deenergizing the heating elements in sequence. Each of the normally open switches includes a switch material with a resistivity that permanently decreases to close the switch in response to heating, and each of the normally closed switches opens in response to heating.
