Gas quantity and composition from the hydrolysis of salt cake from secondary aluminum processing.

ABSTRACT: A systematic approach to understanding the hydrolysis of salt cake from secondary aluminum production in municipal solid waste landfill environment was conducted. Thirty-nine (39) samples from 10 Aluminum recycling facilities throughout the USA were collected. A laboratory procedure to assess the gas productivity of SC from SAP under anaerobic conditions at 50 °C to simulate a landfill environment was developed. Gas quantity and composition data indicate that on average 1400 µmol g^-1 (35 mL g^-1) of gas resulted from the hydrolysis of SC. Hydrogen was the dominant gas generated (79% by volume) followed by methane with an average of 190 µmol g^-1 (21% by volume). N₂O was detected at a much lower concentration (1.2 ppmv). The total ammonia released w
