Disposing of sewage - by combustion, giving synthesis gas

摘要

In a process for disposing of sewage, comminuted waste and solid waste and/or conc. and dehydrated sewage and solid waste are mixed with a combustible liq. hydrocarbon, a slurry of such a hydrocarbon with C particles, an aq. slurry of C particles and/or water, as flow-auxiliary, to give a reaction mixt., which is led into a non-packed, non-catalytic free-flow gas generator, where the reaction mixt. is partially oxidised with a gas contg. free O2 and steam, under the normal conditions of the synthesis gas or heating gas reaction, to give a hot gaseous end-prod. contg. H2, CO, CO2, water and C particles. A cheap, continuous process is provided, giving a useful by-prod., e.g. synthesis gas. Discharge of waste into rivers is avoided.
