    Abstract: Fischer-Tropsch synthesis is performed on a CO/H*2 feed gas using a plurality of compact catalytic reactor modules (12) each defining catalytic reaction channels and coolant channels, in two successive stages, with the same number of reactor modules for each stage. The gas flow velocity in the first stage is sufficiently high that no more than 75% of the CO undergoes conversion. The gases are cooled (16) between successive stages so as to remove water vapour, and the pressure is reduced (20) before they are subjected to the second stage. In addition the reaction temperature for the second stage is lower than for the first stage, such that no more than 75% of the remaining carbon monoxide undergoes conversion during the second stage too. The deleterious effect of water vapour on the catalyst is hence suppressed, while the overall capacity of the plant (10) can be adjusted by closing off modules in each stage while keeping the numbers equal.

    Abstract: A catalytic reactor (20) comprises a plurality of sheets (21) defining flow channels (22) between them. Within each flow channel (22) is a foil (24) of corrugated material whose surfaces are coated with catalytic material. Flow channels (22, 22a) for a first gas extend in oblique directions relative to the flow channels (22b) for a second gas. The reactor (20) incorporates header chambers (26, 28) to supply gas mixtures to the flow channels (22), the headers communicating with adjacent channels being separate. The reactor (20) enables different gas mixtures to be supplied to adjacent channels (22), which may be at different pressures, and the corresponding chemical reactions are also different. Where one of the reactions is endothermic while the other reaction is exothermic, heat is transferred through the sheets (21) separating the endothermic reaction. When the catalyst is one set of flow channels becomes spent, it can be replaced by removing a header. The reactor (20) may be used in a compact plant to perform steam/methane reforming, obtaining the necessary heat by catalytic methane combustion, and also for Fisher-Tropsch synthesis, so that the overall process involves conversion of methane to long-chain hydrocarbons.

    Abstract: A valve assembly (10) comprises a valve stem (14) with a bore (15) and radial apertures (17), and a sleeve (18) closed atone end and slidable over the valve stem (14) to obstruct the apertures (17). At the end of the valve stem opposite the outlet end, the valve stem (14) defines a fluidic vortex chamber (22) with both tangential inlets (28) and non-tangential peripheral inlets (26), and with an axial outlet (24) communicating with the bore (15). The sleeve (18) defines at least one radial port (32) near its closed end. The valve assembly operates in a conventional fashion except when approaching closure. Once the last of the apertures (17) in the valve stem has been closed, the only flow path is through the fluidic vortex chamber (22). Further movement of the sleeve (18) alters the distribution of the flow between the non-tangential inlets (26) and the tangential inlets (28), so adjusting the strength of the fluidic vortex and the resistance to fluid flow. The valve assembly (10) suppresses erosive and cavitational wear of the valve mechanism, and can provide a wide range of flow modulation.

    Abstract: A compact catalytic reactor comprises a stack of plates (72, 74, 75) to define a multiplicity of first and second flow channels arranged alternately in the stack; each flow channel in which a chemical reaction is to take place is defined by straight-through channels across at least one plate, each such straight-through channel containing a removable gas-permeable catalyst structure (80) incorporating a metal substrate. The first flow channels (76) are oriented in a direction that is perpendicular to that of the second flow channels (77), and between successive second flow channels in the stack the reactor defines at least three side-by-side first flow channels (76); and the reactor incorporates flow diversion means (80; 88) such that the first fluid must flow through at least three such first flow channels (76) in succession, in flowing from an inlet to an outlet. The overall flow paths can therefore be approximately co-current or counter-current.
