WHAT IS HTU ?
o
Conditions 300 - 350 C 120 - 180
bar reaction time 5 - 20 minutes liquid
water present Feedstocks All types of biomass,
domestic, agricultural and industrial residues,
wood. Also wet feedstocks, no drying
required Chemistry Oxygen removed as Carbon
Dioxide, and Water Products 45 Biocrude (w on
feedstock, DAF basis) 25 Gas (gt 90 CO2) 20
H2O 10 dissolved organics (e.g., acetic acid,
ethanol) Thermal efficiency 70 - 90

Biocrude Product Properties
o
Biocrude Heavy organic liquid, solidifies at 80
C Not miscible with water Oxygen content 10 -
18 w, H/C 1.1 LHV 30 -35 MJ/kg Separation
into light and heavy fractions by flashing or
extraction Light Biocrude Contains no
minerals Can be upgraded by HDO Heavy
Biocrude Co-combustion in coal power
station green electricity Gasify green
hydrogen, partly used for HDO
16
Upgrading of Light Biocrude by HDO
  • HDO HydroDeOxygenation
  • similar to existing refining processes
  • First stage hydrocracking, HDS, HDN
  • Experimental evidence (Shell Research, 1983)
  • small scale exploratory experiments
  • O, N, S reduced to low concentrations
  • hydrogen consumption around 5w
  • Products fractionated
  • Gas oil fraction examined in experiments by
  • Shell Products Lab, UK
  • Ignition properties better than average fossil
    gas oil.

PROCESS RD ACHIEVEMENTS
  • Pressurizing of feedstock successfully proven
    with commercial prototype pump
  • Successful longer-duration pilot plant run
  • Product applications defined
  • Experimental evidence gives excellent transport
    fuel properties for HTU diesel (demo program
    defined)
  • (Basic) process design and cost estimates by
    Jacobs Engng. Nederland confirm
    positive expectations
  • HTU selected as one of the promising routes to
    Bio-Fuel
  • Energy Transition programme of Dutch Ministry
    of Economy
  • HTU is ready for commercial demonstration
    (HTU-1)

HTU DRIVERS
  • Cheap (lt2/GJ) Biomass Residues and Waste
  • Production of clean diesel fuel, fully
    compatible with conventional fossil diesel
  • Competitive with fossil diesel (30/bbl crude),
    without subsidy or fiscal incentives
  • Significant reduction potential for CO2
  • No competition with land for food
  • Security of energy supply

    basis)
  • Capital investment 19M Euro, incl. 40
    contingency
  • Startup 2008/2009
  • Integrated with new Waste Incinerator, Amsterdam
  • Operators, Maintenance, Waste water treatment, No

HTU TRANSITION PATH
  • Start-up HTU-1 in 2008/2009
  • Demonstration HTU-Diesel in 2009
  • 2010-2020-gt capacity growth at 30/year
    (biomass input 4M ton (db)/year)
  • 2020-2040-gt capacity growth at 10/year
    (biomass input 30M ton (db)/year)

27
HTU VISION 2040
  • HTU will become top player for transport
    diesel/kerosene from (wet) biomass
  • Competes 2015 in level playing field with
    fossil fuels at 30/bbl and lt2/GJ biomass
    feedstock cost
  • 400 PJ/year renewable products from 30M tons
    (db)biomassa per year (lt1 of world resource of
    biomass residues)
  • Investment 10 Billion
  • CO2 reduction 50 M tons/year
