Journal ArticleDOI
Hydrothermal liquefaction of biomass: Developments from batch to continuous process
TL;DR: This review describes the recent results in hydrothermal liquefaction (HTL) of biomass in continuous-flow processing systems, and process models have been developed, and mass and energy balances determined.
Journal ArticleDOI
Process development for hydrothermal liquefaction of algae feedstocks in a continuous-flow reactor

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.
Journal ArticleDOI
Techno-economic analysis of liquid fuel production from woody biomass via hydrothermal liquefaction (HTL) and upgrading
TL;DR: In this paper, the feasibility of developing a commercial large-scale woody biomass HTL and upgrading plant was evaluated, and the annual production rate for the final hydrocarbon product was estimated to be 42.9 and 69.9 million gallon gasoline-equivalent (GGE) for the SOT and goal cases, respectively.
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
Impact of heterotrophically stressed algae for biofuel production via hydrothermal liquefaction and catalytic hydrotreating in continuous-flow reactors
Karl O. Albrecht,Yunhua Zhu,Andrew J. Schmidt,Justin M. Billing,Todd R. Hart,Susanne B. Jones,Gary D. Maupin,Richard T. Hallen,Toby Ahrens,Daniel B. Anderson +9 more
TL;DR: In this article, two algal feedstocks were prepared for direct comparison of their properties when converted to liquid hydrocarbon fuel, and a technoeconomic analysis of the process for converting each feedstock to liquid fuels was also conducted.
