To　study　the　effect　of　biogas　production　with　a　single　component　in　the　waste,　the　phenomena　of　biogas　production　with　the　groups　of　fat　powder,　cellulose　powder　and　protein　powder　inoculated　respectively　in　activated　sludge　from　Liu　Minying　biomass　pool　and　Xiao　Hongmen　Sewage　Plant　were　observed　simultaneously.　Six　reactors　in　total　were　settled.　Gas　production　and　the　component　of　the　biogas　were　monitored　by　GC　everyday.　Three　single　materials　and　the　sludge　were　inspected　with　infrared　spectrometer　from　the　beginning　of　the　installment　of　the　reactors.　The　results　of　the　experiments　show　that　cellulose　powder　has　the　best　ability　on　the　respect　of　methane　production,　and　fat　powder　is　worse　than　cellulose　powder　but　better　than　protein　powder.　On　the　respect　of　hydrogen　production,　protein　powder　is　the　best　and　the　other　two　materials　produce　gas　without　hydrogen　at　all.　Compared　with　sludge　from　the　two　different　origins,　sludge　from　Liu　Minying　biomass　pool　is　better　both　on　methane　and　hydrogen　production.　The　difference　of　sludge　FTIR　figures　between　Liu　Minying　biomass　pool　and　Xiao　Hongmen　Sewage　Plant　can　explain　this　to　some　degree.　(C)　2012　Selection　and/or　peer-review　under　responsibility　of　Basel　Convention　Coordinating　Centre　for　Asia　and　the　Pacific　and　National　Center　of　Solid　Waste　Management,　Ministry　of　Environmental　Protection　of　China.
