• CHRISGAS
• Clean Hydrogen-RIch Synthesis GAS
• A General Project Presentation

2
CHRISGAS Project Objectives

• To show production of clean hydrogen-
• rich synthesis gas from cellulosic
• biomass in pilot scale within 5 years
• Actual production of vehicle fuel is not
• included in the present project
• Quantitative targets
• 18 MWth
• 3 500 Nm3/hr H2 equivalent

3
CHRISGAS Long-term Aims

• From a clean hydrogen-rich synthesis gas, almost
  any vehicle fuel can be produced
• Possible future fuels are dimethyl ether (DME),
  synthetic diesel fuel, hydrogen, methanol
• The key is the synthesis gas quality

Two Parts of the Project
Pilot Plant Establishment VVBGC Will make use
of the Värnamo plant
Research Development CHRISGAS Will take place
on-site at the Project Partners
Project Co-ordination Office is at Växjö
University, Sweden

The Process - Main Steps

• Raw material - Biomass
• Characteristics? Supply?
• Gasifier at 10-20 bar
• How do you feed particles into the gasifier?
• Gasifier produces raw gas
• How do you clean and filter hot gas?
• Gas composition adjustment
• How do catalysts react to gas impurities?

9
Key Process Step

• For best efficiency in later process steps,
• the final gas analysis shall be approximately
  Hydrogen/Carbon monoxide 2
  with a very low hydrocarbon content
• So the raw gas is upgraded by steam reforming and
  water-gas-shift reactors using catalysts
• The catalysts are sensitive to ash and other
• impurities in the biomass
• This gas quality upgrading from raw to
• final gas is crucial to the process

10
Lab. R D Activities

• Feedstock (biomass) logistics
• Biomass drying process integration
• Pressurised fuel feeding (piston feeder)
• Gasification, hot synthesis gas characterisation
  (laboratory and bench-scale work)
• High temperature filtration/cleaning
• (e.g. S) at up to 900C
• Catalytic steam reforming (decay deactivation)
• Shift gas catalyst characterisation

11
Pilot-scale VVBGC Act.

• Based on the existing Värnamo plant
• Plant retrofit will include
• Steam/oxygen-blown gasification of biomass
• Hot gas cleaning (to remove particulates) at
• up to 900C
• Catalytic high temperature steam reforming
• (of tar and light hydrocarbons, incl. CH4)
• Water gas shift to hydrogen-rich gas

12
Other Project Activities

• Process studies (e.g. novel methods of
  contaminants removal)
• System studies (e.g. preferred process H2,
  methanol, DME, FT fuel availability cost
  plant capacity cost of product modelling)
• Studies on the Socio-economic impact
• - emissions
• - jobs created
• - regional growth

13
Information Training Activities

• Training (University courses, specialists
  training, vocational training at Värnamo)
• Dissemination (incl. increasing public awareness
  and workshops)

14
After CHRISGAS

• we will know
• How to transform biomass into the required gas

Clean and hydrogen-rich synthesis gas
15
After CHRISGAS

• we will have
• An international research and educational centre
• established in Värnamo in south Sweden

with different biofuel qualities in store
16
After CHRISGAS

• we will have
• The knowledge needed to start producing vehicle
  fuel from renewable sources
• An educational and training centre for those who
  will take part in and further develop such
  production.
• So we will be better prepared to
• meet the future
