Ammonia Synthesis Gas and Petrochemicals from Cattle Feedlot Manure

摘要

The pyrolysis and partial oxidation of cattle feedlot manure are discussed. Previous studies by the investigators as well as the pioneering work of R.C. Bailie are reviewed. A description of the current reactor which has a throughput of one-half ton per day and experimental results on the simultaneous production of 0.4 to 1.2 liter ammonia synthesis gas per g. of dry ash-free manure and 25 to 65 kg ethylene per metric ton of dry ash-free manure are given. A basis for the production of the ethylene and other petrochemicals is discussed along with recent results on the decomposition of intermediate tar and liquids. The application of process technology to other feedstocks, use of oxygen instead of air, and a discussion of different reactor designs are also presented. (ERA citation 04:022049)
