Abstract: Systems and methods are provided for using size-reversing materials in vessels where direct heating is used to at least partially provide heat for reforming reactions under cyclic reforming conditions. An example of a size-reversing material is the combination of NiO and Al2O3. It has been discovered that size-reversing materials can undergo a phase transition that can assist with re-dispersion of metal at elevated temperatures. This can assist with maintaining catalytic activity for reforming over longer time periods in the presence of cyclic reforming conditions.

Abstract: An apparatus for continuous preparation of carbon nanotubes, based on a fluidized bed reactor. The fluidized bed reactor comprises an annular varying diameter zone, a raw material gas inlet, a catalyst feeding port, a protective gas inlet, and a pulse gas controller. The annular varying diameter zone is located at a zone from a ¼ position starting from the bottom to the top. The pulse gas controller is disposed at the arc-shaped top portion of the annular varying diameter zone. The catalyst feeding port is located at the top of the fluidized bed reactor. The raw material gas inlet and the protective gas inlet are located at the bottom of the fluidized bed reactor. The device is also provided with a product outlet and a tail gas outlet. The device has a simple structure and low cost, is easy to operate, has a high raw material utilization rate, can effectively control the problem of carbon deposition on the inner wall of a primary reactor, can manufacture high-purity carbon nanotubes, and is suitable for large-scale industrial production.

Abstract: A process for hydrogen recovery from refinery gas system comprising supplying the refinery gas to an inlet manifold fluidly coupled to a conditioning stage, the conditioning stage comprising a reactor having a reforming catalyst deposited on an ultra-short-channel-length metal substrate; supplying oxidant to the conditioning stage via the inlet manifold; supplying steam from a steam generator to the conditioning stage via the inlet , manifold; reacting the refinery gas in the conditioning stage; and discharging a product through a discharge outlet fluidly coupled to the conditioning stage, the discharge outlet configured to flow the product for use by a downstream reformer. The process allows to either increase the H2 production rate or lower the firing rate while maintaining a constant H2 production rate for the downstream steam reformer, independent of the feed compositional variability of the refinery or still gas.
