Fuel Gas Production from Solid Waste.

摘要

This report contains two final reports from Dynatech subcontractors. Part 1consists of the report of the MIT program,Fuel Gas Production from Solid Waste by Thermophilic Anaerobic Digestion. The advantages of thermophilic digestion over the traditional mesophilic digestion are discussed. The primary drawback to thermophilic digestion is the need to supply heat to maintain the temperature above 50degrees C. It is concluded that anaerobic thermophilic digestion of cellulose waste is a feasible operation for the production of fuel gas. The effects of residence time,recycle,and temperature on the extent of solid waste degradation,biological mass formed,and quantity and quality of gas produced are discussed. Recommendations for future research are presented. Part 2is entitled Fuel Gas from Solid Waste and is the final report from the Univ. of Massachusetts. It contains three sections:Kinetic Studies on Anaerobic Digestion of Solid Waste;Feasibility of an On-Line Instrument for Measuring Anaerobic Digestion Microbial Activity;and Development of Process Techniques for Microorganisms Separation. Details of digester operation are included.
