| Abstract |
A pilot plant was designed and constructed to produce char via the St. Regis hydropyrolysis kraft chemical recovery process and to produce activated carbon from the char. This report includes discussion of laboratory and prepilot work, the pilot plant, and presents operating results. After a period of optimizing feed pretreatment, temperature and pressure conditions in the hydropyrolysis section of the plant, about 22,000 kg of char was produced for activation. The char was converted to a high quality granular activated carbon having properties which compared favorably with commercially available carbons. The concept of on-site production of activated carbon and the use of such carbon for local effluent treatment has been demonstrated to be technically sound. The cost of on-site production of hydropyrolysis activated carbon in quantities required for local effluent treatment is not competitive with commercially available carbons. To become competitive, the plant would have to supply carbon for effluent treatment at several locations. To achieve significantly lower costs would require entry into market production. |
