  • Method for recovering phosphorus
    Patent number: 11167989
    Abstract: The present invention concerns a method for recovering phosphorus by thermochemical reaction of a phosphorus-containing material such as an alternative fuel, for example, in the presence of calcium-containing particles in a moving bed reactor and subsequent separation of fines enriched with phosphorus from the moving bed reactor. Furthermore, the present invention concerns the use of a recyclable material obtained by the method as a fertilizer or fertilizer additive.

  • METHOD FOR PRODUCING A METHANE-RICH PRODUCT GAS AND REACTOR SYSTEM USABLE FOR THAT PURPOSE
    Publication number: 20130041051
    Abstract: The invention relates to a method for producing a methane-rich product gas, in which a starting gas containing hydrogen and carbon dioxide is catalytically methanated under the influence of at least one adjustatable parameter in at least two stages and at least one criterion relating to the composition of the product gas is monitored. The criterion is fulfilled under a condition influencing the method and when the condition changes, a change in the parameter setting that preserves fulfilment of the criterion is affected.
