    摘要： A vertical, fixed-bed ammonia converter wherein a fixed-bed catalyst zone is configured into two mechanically separated catalyst volumes and two gas streams that operate in parallel. The design maintains the ratio of gas flow to catalyst volume so that there is no catalyst effectiveness penalty. The catalyst beds and gas flow paths are configured so that gas flow is downward through each catalyst volume. Each fixed-bed catalyst zone in the present invention can hold the catalyst in an annular space formed between two concentric shrouds arranged around a shell and tube heat exchanger. The two catalyst beds associated with each zone are situated above one another along the length of an interstage heat exchanger. Pipes or conduits are disposed through the beds to effect the parallel gas flow configuration, or alternatively, annular flows are created via passages through the internal shrouds that contain the catalyst beds.

    摘要： The invention concerns a process and an apparatus for performing chemical reactions under pressure in the presence of a solid catalyst in a multi-stage reaction zone, after external intermediary thermal conditioning. This process may be used for the synthesis of ammonia or methanol or for gasoline reforming. It is characterized in that at least one reaction fluid is introduced into at least one compartment, a first reaction effluent is recovered, a heat exchange takes place, outside the reaction zone, between a first effluent and an external heat exchange medium, then said first effluent is introduced into at least one subsequent compartment and a second reaction effluent is recovered from said subsequent compartment. The reaction fluid or reaction effluent circulates cross-wise in the compartments substantially perpendicularly to the reaction zone, the compartments being tight and of elongate shape, each compartment being adjacent to one or two other compartments, each group of two adjacent compartments comprising a common partition, wall, either substantially parallel to said generatrix or substantially oblique with respect thereto.

    摘要： A reactor suitable for synthesis of ammonia or methanol comprises a catalyst bed 36 equipped with heat exchange tubes 32 supported by means 28-31 or 40, 42 providing catalyst fillable space between the tubes over substantially their whole length. Preferably catalyst particles between the tubes and in an uncooled bed 36 downstream thereof constitute a single body of catalyst. The reactor is especially suitable for synthesis at low pressures such that the heat transfer area provided by the tubes is relatively low.

    摘要： The present invention is generally directed to an improved process and apparatus for the production of gaseous products such as ammonia by catalytic, exothermic gaseous reactions and is specifically directed to an improved process which utilizes a gas-phase catalytic reaction of nitrogen and hydrogen for the synthesis of ammonia. This improved process for the production of ammonia utilizes an ammonia converter apparatus designed to comprise at least two catalyst stages and a reheat exchanger so arranged as to provide indirect heat exchange of the gaseous effluent from the last reactor catalyst stage with the effluent from at least one other reactor catalyst stage having a higher temperature level in order to reheat the effluent from the last reactor catalyst stage prior to exiting the reactor vessel, thereby facilitating higher level heat recovery from the reactor effluent.
