Journal ArticleDOI
Process development for hydrothermal liquefaction of algae feedstocks in a continuous-flow reactor
Douglas C. Elliott,Todd R. Hart,Andrew J. Schmidt,Gary G. Neuenschwander,Leslie J. Rotness,Mariefel V. Olarte,Alan H. Zacher,Karl O. Albrecht,Richard T. Hallen,Johnathan E. Holladay +9 more
TL;DR: In this article, high levels of carbon conversion to gravity separable biocrude product were accomplished at relatively low temperature (350°C) in a continuous-flow, pressurized (sub-critical liquid water) environment.
ReportDOI
Process Design and Economics for the Conversion of Algal Biomass to Hydrocarbons: Whole Algae Hydrothermal Liquefaction and Upgrading
Susanne B. Jones,Yunhua Zhu,Daniel B. Anderson,Richard T. Hallen,Douglas C. Elliott,Andrew J. Schmidt,Karl O. Albrecht,Todd R. Hart,Mark G. Butcher,Corinne Drennan,Lesley J. Snowden-Swan,Ryan Davis,Christopher Kinchin +12 more
TL;DR: In this article, a preliminary analysis of the costs associated with converting whole wet algal biomass into diesel fuel is presented, where the secondary aqueous product containing significant organic material is converted to a medium btu gas via catalytic hydrothermal gasification.
Journal ArticleDOI
High resolution FT-ICR mass spectral analysis of bio-oil and residual water soluble organics produced by hydrothermal liquefaction of the marine microalga Nannochloropsis salina
Nilusha Sudasinghe,Barry Dungan,Peter J. Lammers,Karl O. Albrecht,Douglas C. Elliott,Richard T. Hallen,Tanner Schaub +6 more
TL;DR: In this article, a detailed compositional characterization of a bio-crude oil and aqueous byproduct from hydrothermal liquefaction of Nannochloropsis salina by direct infusion Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS) in both positive-and negative-ionization modes is reported.
Journal ArticleDOI
Development of hydrothermal liquefaction and upgrading technologies for lipid-extracted algae conversion to liquid fuels
TL;DR: In this paper, a large-scale lipid-extracted microalgae (LEA) conversion to liquid fuels via hydrothermal liquefaction (HTL) and upgrading processes was investigated.
Journal ArticleDOI
Development of a CaO-based CO2 sorbent with improved cyclic stability
TL;DR: In this article, two methods have been proposed for increasing the life cycle performance of a CaO-based sorbent by incorporating an inert material in the sorbent and stabilizing it through controlled sintering.
