    Abstract: Apparatus for rapidly heating one or more reactants for use in a fuel reformer. The apparatus includes a combustion section having an outer wall enclosing a combustion chamber and a catalyst disposed within the combustion chamber. The catalyst provides a non-diffused flow path through the combustion chamber for the combustion of gases and generation of heat and passage of such gases and heat from the combustion chamber. A heat recovery section is in fluid communication with the combustion section and has an outer wall defining a heat recovery chamber. At least one heat exchanging element is located within the heat recovery chamber having an inlet for receiving a fuel reforming reactant and an outlet for directing a heated reactant out of the heat recovery section. The combustion section is elevated relative to the heat recovery section such that heated combustion gases are displaced down into the heat recovery section. The combustion and heat recovery sections have outer walls that are continuous with one another to form a housing that is preferably cylindrical. The housing has an internal diameter of less than about 10 inches, or alternatively, has a length and a diameter in a ratio of between about 7:1 and about 4:1. Methods for the rapid start-up of a fuel processor using such a pre-reformer are also provided, as are integrated fuel processors comprising a fuel reformer and the disclosed pre-reformer.

    Abstract: Improved process for the production of substantially pure methane or clean synthetic natural gas (SNG) including the steps of partial oxidation of a hydrocarbonaceous fuel feed with substantially pure oxygen to produce a process gas stream comprising principally H2, and CO and having a critical mole ratio H2/CO in the range of 1.0 to below 1.5 and preferably 1.0 to 1.3; cooling the process gas stream and separating H2O, CO2 particulate carbon and gaseous impurities therefrom, reacting together the H2 and CO in said process gas stream in a catalytic methanation zone to produce a methane-rich gas stream containing gaseous impurities selected from the group consisting primarily of H2O, and CO2, along with minor amounts of H2, CO, N2, and Ar and mixtures thereof; and removing said H2O and CO2 to produce a product gas stream comprising substantially pure methane i.e. 95 mole % or higher (dry basis). The product gas may be used as a clean substitute natural gas having a gross heating value of about 980 BTU/SCF or higher.

    Abstract: A methane-rich gas stream is produced by catalytic methanation of synthesis gas feed comprising H2 and CO. When the mole ratio H2/CO of the synthesis gas feed is in the range of about 0.5 to 1.15, by adjusting the mole % H2O in the synthesis gas feed to a value in the range of about 0.1 to 15., the gross heating value of the product gas may be increased to a value above that obtained with a dry substantially CO2-free methanator feed gas. This effect of adding H2O becomes more pronounced as the H2/CO ratio drops further below the maximum value of 1.13. Further, in a preferred embodiment the gross heating value of the product gas (with H2O and CO2 removed) was maximized by adjusting the mole % H2O in the synthesis gas feed to the methanator to a critical value in the range of 1.0 to 3.0 and preferably 2.0 while maintaining the H2/CO mole ratio of the synthesis gas feed at a critical value in the range of about 1 to 1.15 and preferably 1.13.

    Abstract: A methane-rich gas stream is produced by catalytic methanation of synthesis gas feed comprising H2 and CO. When the mole % CO in the synthesis gas feed to the methanator is greater than 10 mole %, and the mole ratio H2/CO is in the range of greater than 1.0 to 3, by adjusting the mole % CO2 in the synthesis gas feed to the methanator to a value in the range of about 0.5 to 20, and the mole ratio H2/CO2 in the range of about 2 to 60 and preferably less than 3.9 it was unexpectedly found that a product gas is produced having a gross heating value which is greater than that which is obtained from a dry CO2-free methanator feed gas.

    Abstract: Significant improvement in the recovery of hydrocarbons from a subterranean hydrocarbon-bearing formation containing acidsoluble components is accomplished by injecting into the formation via an injection well drilled into a formation communicating with an adjacent producing well and containing acid-soluble components which may or may not have water-sensitive clays and shales included therein, an aqueous acidic solution of an admixture as hereinafter described whereupon the acid component reacts with the acid-soluble components of the formation creating passageways or enlarging existing passageways thus facilitating the flow of fluids therein and the admixture prevents post-precipitation of dissolved salts and thereby increases the recovery of hydrocarbons from the formation through the adjacent producing well.
