“…The PSC pretreatment with 160 • C/60 min and 190 • C/30 min showed the highest methane yields with 239 mL/g VS and 229 mL/g VS, respectively. Budde et al (2014) [7] published methane yields for untreated manure of at least 162 mL/g OM in BMP tests (30 days) and up to 255 mL/g OM (160 • C/5 min) for cattle manure pretreated with thermal pressure hydrolysis. Furthermore, Budde et al (2014) [7] more often stated results between 216 and 232 mLCH 4 /g OM for treated manure.…”

“…Lab-scale batch tests with cattle manure pretreated with thermal pressure hydrolysis revealed contradictory results. Risberg et al [6] found no improved gas production, while Budde et al [7] measured increased methane yields by up to 58% with a treatment temperature of 180 • C. Besides the positive effect of surface enlargement of a thermal pressure hydrolysis, negative effects may occur due to the formation of inhibiting substances. These substances include phenolic compounds as well as furalaldehydes, e.g., furfural and 5-hydroxymethylfurfural, which are the main degradation products derived from the dehydratation of hexoses or pentoses, respectively (Barakat et al, 2012) [8].…”

Cattle manure is an agricultural residue, which could be used as source to produce methane in order to substitute fossil fuels. Nevertheless, in practice the handling of this slowly degradable substrate during anaerobic digestion is challenging. In this study, the influence of the pre-treatment of cattle manure with pressure-swing conditioning (PSC) on the methane production was investigated. Six variants of PSC (combinations of duration 5 min, 30 min, 60 min and temperature 160 °C, 190 °C) were examined with regards to methane yield in batch tests. PSC of cattle manure showed a significant increase up to 109% in the methane yield compared to the untreated sample. Kinetic calculations proved also an enhancement of the degradation speed. One PSC-variant (190 °C/30 min) and untreated cattle manure were chosen for comparative fermentation tests in continuously stirred tank reactors (CSTR) in lab-scale with duplicates. In the continuous test a biogas production of 428 mL/g volatile solids (VS) (54.2% methane) for untreated manure was observed and of 456 mL/g VS (53.7% methane) for PSC-cattle-manure (190 °C/30 min). Significant tests were conducted for methane yields of all fermentation tests. Furthermore, other parameters such as furfural were investigated and discussed.
