FT-Anlage / Controlling
11
FT-slurry reactor and condensation
  • -FT-slurry reactor
  • - volume max 20 l
  • - diameter 10 cm
  • -Typical parameters of operation
  • 20 bar
  • 230C
  • Catalyst in use
  • Supported cobalt-ruthenium catalyst (20 Co
    1Ru)
  • -Condensation in two steps
  • - scrubber to remove heavy compounds (80C)
  • - gas heat exchanger (temperature 6C)

12
Gas treating and compression
  • Removing of water
  • RME-scrubber
  • RME temperature 3C
  • Gas temperature 5C
  • Compression
  • Membrane pumps
  • pressure up to 5 bar
  • Maximator
  • (duplex compressor runs with 6 bar
  • compressed air)
  • pressure up to 30 bar

13
Gas cleaning section
  • Sodium aluminate
  • remove chlorine
  • HDS-catalyst ( R-S-R ? H2S )
  • organic sulphur into H2S
  • Zincoxide
  • remove H2S
  • Copper based absorbent
  • deep desulphurisation
  • Activated carbon
  • remove organic sulphur and H2S
  • (device installed before the compression)
  • All reactions in fixed bed reactors

14
Different Gas Cleaning systems
  • Sodium aluminate
  • HDS-catalyst
  • Zinc oxide
  • HDS-catalyst
  • Zinc oxide
  • Copper based absorbent
  • Activated carbon
  • Zinc oxide
  • Copper based absorbent

15
Analytics
  • Sulphur
  • Sulphur Chemiluminescence Detector
  • (in cooperation with the Paul Scherer Institute,
    Switzerland)
  • Adsorption in methanol at -20C and GC-MS
    analyses
  • Gas
  • GC-TCD/FID
  • (CO, CO2, N2, CH4, C2 C5 compounds)
  • Liquid
  • GC-FID
  • (simulated distillation)
  • Fuel Analyses EN 2502004
  • (realized by ITN, Poland)

16
FT-Gas Cleaning / Deactivation
  • HDS-catalyst
  • Zinc oxide
  • Copper based absorbent

17
FT-Gas Cleaning
  • Activated carbon
  • Zinc oxide
  • Copper based absorbent

Summary
  • Project shows realization of BTL-concept
  • Experiences on gas cleaning and catalyst activity
    show the importance of deep desulphurisation of
    the syngas or the development of new catalysts
  • Calculated allowed sulphur concentration in the
    syngas are only some ppb
  • High quality diesel can be obtained
  • Cold Filter Plugging Point and density out of the
    norm
  • (Isomerisation may change the behaviour )
  • Other parameters fulfil the norm
