Thermochemical Reactions of Blue Gum and Fossil Wood with CO/H2O: Some Mechanistic Comments
(American Chemical Society, 2015-12-04)
Our previous work suggested that liquid product yields from wood, unlike those from other biomass types, were not increased by CO/H2O reaction. Reactions of blue gum (BG) and fossil wood (FW) using high-temperature, ...
Thermo-chemical reactions of algae, grape marc and wood chips using a semi-continuous/flow-through system
(Elsevier BV, 2015-06-16)
Chlorococcum sp., grape marc, and Pinus radiata have been reacted in a semi-continuous (flow through) system at 425 C under a flow of N2 or H2 and results compared to those from batch autoclave experiments. This paper ...
Improvement in liquid fuel product quality from reactions of grape marc with CO/H2O
(Elsevier BV, 2015-06-19)
Reactions of grape marc with CO/H2O have been investigated over a range of temperatures (320–425 C) with and without added sodium carbonate (Na2CO3) or sodium aluminate (NaAlO2) with a view to optimising liquid fuel quality. ...
