Characterisation of the products of low temperature pyrolysis of Victorian brown coal in a semi-continuous/flow through system
(Elsevier BV, 2018-07-24)
Two Victorian brown coal samples, a run-of-mine Loy Yang coal (LY) and a Loy Yang light lithotype (LL), were subjected to pyrolysis at 420–460 °C and 330–460 °C, respectively, under a continuous nitrogen flow. The process ...
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 ...
Pressurized thermal and hydrothermal decomposition of algae, wood chip residue, and grape marc: A comparative study
(Elsevier Ltd., 2014-08-22)
Pressurized thermal decomposition of two marine algae, Pinus radiata chip residue and grape marc using high temperature, high pressure reactions has been studied. The yields and composition of the products obtained from ...
Reactions with CO/H2O of Two Marine Algae and Comparison with Reactions under H2 and N2
(American Chemical Society, 2014-04-21)
The reactions of a strain of marine alga Chlorococcum sp. and of a polystrain containing a mixture of marine algae with CO/H2O have been studied. The yields and chemical composition of the products obtained from the reactions ...
Pyrolysis-GC/MS analysis of biomass and the bio-oils produced from CO/H2O reactions
(Elsevier, 2016-05-22)
Py-GC/MS of microalgae (Chlorococcum sp.), grape marc and wood chips (Pinus radiata) and the bio-oils produced from CO/H2O reactions ofthese substrates has been studied. The Py-GC/MS technique provided a more complete ...
