Low Temperature Pyrolysis of Black Liquor and Polymerization of Products İn Alkali Aqueous Medium
(1991) Demirbaş, A; Uçan, H.İ.
Atmospheric pressure pyrolysis for the production of liquids and gases from black liquor and its calcium salts and acidic precipitate have been carried out in a little stainless steel tube. Yields, sum of liquid and gas products, from black liquor and its calcium salts and acidic precipitate were 44.7%, 52.0% and 59.1% of dry basis respectively. The precipitates obtained from black liquor by acidifying with hydrochloric acid and passing carbon dioxide have been polymerized in aqueous acetone containing formaldehyde and ammonia, and converted a polymeric resin. © 1991, Taylor & Francis Group, LLC.
