However, within the range of pretreatment severities tested, feedstock reactivity appeared to reach a broad maximum of 70 to 80% at the higher combined severities.
The HS-FCC technology has been tested with various feedstocks at different capacities.
The carbonaceous feedstocks tested were industrial and sewage sludges, scrap tire powder, fluff, South African coal, and beech charcoal, and are characterized by having a wide range of volatile, ash, and fixed carbon contents, elemental compositions, and physical properties.
XMG removal followed similar trends for the different feedstocks tested, although slightly lower values were obtained for poplar, as illustrated in Figure 3B.
Since glucan conversion exhibits much more variability than XMG removal among the three feedstocks tested, factors other than XMG removal must affect the amenability to enzymatic attack.
In this study, a pilot scale of 100 t/year biodiesel production system, mainly consisting of a fixed-bed and a down-stream plug-flow reactors, was setup to test different feedstock oils, especially a kind of high-acidified oil, trap grease, for their feasibility as biodiesel feedstock in China.
Two alternative drum chipper designs were tested on different feedstock types and under different knife wear conditions.
This technology, which have already been demonstrated and tested, allows treating feedstock with more than 80% moisture content and can lead to high SNG conversion efficiencies.
In this study, utilization of Chlorella vulgaris (a fresh water microalga) and Dunaliella tertiolecta (a marine microalga) biomass was tested as a feedstock for anaerobic H2 and CH4 production.
