procedures to prevent the pollution of the atmosphere by exhaust gases from combustion processes, in particular by exhaust gases of combustion engines and device for implementing the procedure

摘要

Discharge of harmful gases, eg. unburned hydrocarbons, CO, oxides of N and SO2 into the atmos., is prevented by treatment with steam in presence of a body contg. Ge or Ce. The harmful gases are esp. exhaust gases from an i.c. engine. The process can also be applied to turbine engines, turbo-reactors, domestic heating appliances and industrial flues. The engine power and fuel consumption are improved. The amts. of CO, unburned hydrocarbons, oxides of N and SO2 discharged are nil, compared with 4-5.5% CO and 1-3% of the other gases for an untreated engine. The engine operates easily on a lean combustion mixt., in contrast to an untreated engine. Treatment is esp. over an alloy or cpd. of Ge or Ge with a metal, e.g. Fe, contg. 0.5-100 (36-40)% Ce or 45-80% Ge.
