Velocys technology
• Microchannel reactor— Enhanced heat and mass transfer rates— Close coupling of exothermic reaction with
steam generation• Superior catalysts
— High activity and selectivity• Principles of design and operation
— Particulate catalyst in small channels— Cross-flow with syngas downflow
• Strengths— Isothermal behavior – thermally stable— Extremely robust to upsets— Strong economy of mass manufacturing— Installed spares relatively cheap— High on-stream factor— Extremely high volumetric productivity— Ease of modularization
Compact, robust, efficient and economic

Process performance
• 1 process channel— No catalyst dilution— Coolant channels with hot oil
circulation
• During scale-up, number of channelsincreases, size does not#
• Validate commercialization requirements— Stability— Regenerability— Catalyst life— Predictive models— Tolerance to feed contaminants,

Path to commercialization
• Organic Matrix Combustion (OMX)— Novel synthesis method— Yields highly active and stable
catalysts
• FT catalyst— Activity depends on small sizes
of Co3O4 particles— Stability depends on a narrow
particle size distribution
• OMX yields an optimum averageCo3O4 particle size yielding astable, high activity FT catalystupon activation

The industrially produced Velocys catalyst exhibits an apparent TOF3-6 times higher than typical Co FT catalysts at 5° C lowertemperature – Co surface area determined by H2 adsorption

Activity is gained through both loading density and ahigher intrinsic reaction rate
Lower TOF based oncontraction of oxidecrystallites from XRD
Higher TOF based onH2 chemisorptioncapacity and extent ofreduction – particlediameter estimate toolarge based on supportpore diameter
High, stable reactor performance requires uniformpressure drop (and hence flow) from channel-to-channel
• Multiple factors affect pressure drop:— Nominal size— Gross size distribution— Packing density— Packing uniformity— Detailed fines content
• Successful charging requires:— Controlled particle characteristics— Generation of a uniform particle
size distribution for the wholecharge
• Charging technology and catalystcharge characteristics must bematched, controlled, and standardized
~ 0.1-10 mm
Microchannel
16
Controlling flow uniformity requires care in preparing andcharging catalyst
• A standardized charge wasspecifically created to yielduniform packing
• Grab samples were collectedfrom by scooping from differentportions of the original lot
• Standardized samples yieldflow characterized byexperimental variability
• Randomly selected chargesyield widely varying flowcharacteristics
• Standard methods ofmeasuring particle sizedistributions can be inadequateto fully distinguish differences
