Synthesis gas generation by gasifying moist clarifying sludge - together with additional fuel whereby sludge components are oxidised odourlessly

摘要

Synthesis gas is prepd. by gasifying still moist clarifying sludge, (A), with additional fuel (B), e.g. C dust, heavy heating oil and combustible waste. The generated gas can be used as heating- or synthesis gas. All substances in (A) are oxidised odourlessly. (B) quantity should be sufficient to use the water in (A) to gasify the organic components of (A) and (B). The 2nd gasifying agent is O2, e.g. as air or O2-enriched air. A self-feeding combustion process is advantageous, e.g. at 900-1000 degrees C. Standard reactors can be used, esp. turbulent layer- or rotary furnaces, but not countercurrent generators.
