  • Methods and apparatus for enhancement of mass transfer of a fluid in a porous matrix system containing biomass
    Patent number: 6329196
    Abstract: A biological process is enhanced by a method and apparatus used to contact a biomass with a gas and with a nutrient liquid. A resiliently compressible porous matrix system containing the biomass is mounted in a reaction vessel containing a body of the nutrient liquid and a body of the gas above the body of the liquid. The body of liquid having an upper surface exposed to the body of gas and defining a liquid-gas interface. The resiliently compressible porous matrix system is located in a position in the reaction vessel so that compressible porous matrix system is partly immersed in the nutrient liquid and partly extends above the upper surface of the liquid into the body of gas.

  • Integrated reaction process
    Patent number: 4052148
    Abstract: A process in which a substance undergoes endothermic change within a predetermined temperature range in at least one stage of the process and is subsequently subjected to a substantially higher temperature in a further stage of the process, characterised in that effluent heat from said further stage is augmented and the resultant supply of heat is applied partly to the generation of power, and partly to said endothermic change.
