abstract = "By employing metal salts in dilute-acid pretreatment the severity can be reduced due to reduced activation energy. This study reports on a dilute-acid steam pretreatment of spruce chips by addition of a small amount of ferrous sulfate to the acid catalyst, i.e., either SO(2), H(2)SO(3) or H(2)SO(4). The utilization of ferrous sulfate resulted in a slightly increased overall glucose yield (from 74{\%} to 78{\%} of the theoretical value) in pretreatment with SO(2) and H(2)SO(3). Impregnation with ferrous sulfate and sulfuric acid did not give any improvement compared with pretreatment based solely on H(2)SO(4).",
