    Abstract: A metal substrate is coated with a layer of ceramic, by spraying droplets of a slurry of a ceramic precursor onto the substrate, the substrate being at a temperature between 500° C. and 750° C. The ceramic comprises alumina, and is made macroporous by spraying a mixture of alumina sol and alumina particles with no more than 35% by weight of dispersible alumina. Spraying onto a red-hot surface in this fashion leads to a very marked improvement in adhesion of the resulting ceramic to the metal substrate. A catalytically active material may then be incorporated in the ceramic layer, so as to form a catalyst structure (16).

    Abstract: A valve system (10) controls the fluid flow between an inlet (12) and an outlet (14). The system (10) splits the flow into two parallel flow ducts (15, 16) and recombines the flows through opposed tangential inlets (18) and (19) of a fluidic vortex valve (20) which has an axial outlet (22). An adjustable valve (24) controls the flow through one of the parallel flow ducts (15), controlling the strength of the vortex generated within the vortex valve (20). Hence a small valve (24) can control and adjust the flows in both ducts (15 and 16).

    Abstract: Biological waste materials are mixed with water and subjected to intense ultrasonic irradiation (14), before being supplied to an anaerobic digester (16), so that a biogas is generated which contains methane. The biogas is supplied to a catalytic reformer unit (20) to form a synthesis gas; steam may also be supplied, and the proportion of steam to methane is adjustable so that the synthesis gas may be rich in hydrogen or alternatively rich in carbon monoxide. Adjusting the proportion of steam to biogas enables the output of the process to be adjusted according to market conditions. If the synthesis gas is rich in hydrogen, it may be supplied to a fuel cell (26) to generate electricity, while if it is rich in carbon monoxide, it may be used to generate liquid hydrocarbons in a Fischer-Tropsch synthesis reactor (32).

    Abstract: Fischer-Tropsch synthesis is performed using a compact catalytic reactor unit (10) defining channels in which is a gas-permeable catalyst structure (16), the channels extending between headers (18). The synthesis occurs in at least two stages, as the reactor unit provides at least two successive channels (14, 14a) for the Fischer-Tropsch synthesis connected by a header, the gas flow velocity through the first channel being sufficiently high that no more than 65% of the carbon monoxide undergoes conversion. The gases are cooled (25) in the header between the two stages, so as to condense water vapour, and then pass through the second channel at a sufficiently high gas flow velocity that no more than 65% of the remaining carbon monoxide undergoes conversion. This lowers the partial pressure of water vapour and so suppresses oxidation of the catalyst.
