    Abstract: This invention provides an improved, simple and energy saving process for producing a gas containing methane, which process utilizes a reactor having a catalyst bed of a structure wherein a synthesis gas is allowed to pass perpendicularly to the longitudinal directions of a plurality of cooling tubes installed vertically within the catalyst bed. Within the cooling tubes, a liquid coolant at its boiling temperature is flowed upwardly under pressure. A portion of the reaction product gas leaving the catalyst bed is mixed, without cooling, with fresh feed gas and is recirculated to the catalyst bed. The amount of the recycled gas is less than 5 times the amount of fresh feed gas. The foregoing process produces a product gas containing methane from a feed gas containing carbon monoxide and hydrogen.

    Abstract: A radial ammonia converter system including first and second heat interchangers and first, second and third catalyst beds. The synthesis gas is heated in said first and second interchangers by catalyst bed effluent prior to full flow through each of the catalyst beds. In one embodiment, two of the catalyst beds are mounted with the first and second interchangers in one vessel; and in another embodiment, the first interchanger and second catalyst bed are mounted in one vessel and the second interchanger and first catalyst bed are mounted in a separate vessel. In both embodiments, the radial ammonia converter system is completed by a third catalyst bed in a separate vessel.

    Abstract: There is provided an improved panel bed of granular material useful for chemically or physically treating a gas and a granular material in a countercurrent contact. The contacting equipment is unusually compact and affords an unusually low pressure drop in the gas. Free surfaces of the granular material for entry of gas are supported cooperatively by "louvers" each having a gently curved upper surface, the outer edge of which supports the outer edge of a given free surface. The gently curved upper surface of the louver inclines from its outer edge first downward and toward the granular material bed and then upward toward an inner edge relatively deep within the granular material bed. The inner edge of a supporting surface is either above the inner edge of the superjacent free surface of granular material or, if below, a line drawn through these edges is inclined at an angle of less than about 45.degree. to the horizontal. A zone for countercurrent contacting of gas and the granular material is formed between each adjacent pair of supporting louvers. "Cleaning" is by puffback to remove granular material "spent" by the treatment, together with accumulated dust if the treatment includes gas filtration.
