    • Pyrolysis-GC/MS study of fast growing wood Macaranga gigantea 

      Subagyono, RR Dirgarini; Qi, Ying; Sanjaya, Ari Susandy; Amirta, Rudianto; Chaffee, Alan L. (IOP Publishing Ltd., 2019-08-16)
      Py-GC/MS study on fast growing wood Macaranga gigantea at different temperatures has been conducted. The pyrolysis yields and chemical compounds obtained based on the pyrograms of the biomass by Py-GC analyses were compared ...

    • Reactions with CO/H2O of Two Marine Algae and Comparison withReactions under H2 and N2 

      Subagyono, RR Dirgarini; Marshall, Marc; Jackson, W. Roy; Chow, Meechin; Chaffee, Alan L. (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 ...

    • Thermo-chemical reactions of algae, grape marc and wood chips using a semi-continuous/flow-through system 

      Subagyono, RR Dirgarini; Marshall, Marc; Fei, Yi; Jackson, W. Roy; Chaffee, Alan L. (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 ...

    • Thermochemical Reactions of Blue Gum and Fossil Wood with CO/H2O: Some Mechanistic Comments 

      Subagyono, RR Dirgarini; Marshall, Marc; Jackson, W. Roy; Fei, Yi; Chaffee, Alan L. (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, ...

    • Upgrading Microalgal Biocrude Using NiMo/Al-SBA-15 as a Catalyst 

      Subagyono, RR Dirgarini; Marshall, Marc; Jackson, W. Roy; Auxilio, Anthony R.; Fei, Yi; Chaffee, Alan L. (American Chemical Society, 2020-04-03)
      Biocrude from Chlorococcum sp. algae was hydrotreated in batch autoclaves in the presence and absence of Al-SBA-15 supports and NiMo/Al-SBA-15 catalysts with different Si/Al ratios and hence different acidities. Reaction ...
