Alternative Fuels Research: Practical Applications and Foundational Questions
Heinz J. Robota, Ph.D.
Ohio Research Scholar in Alternative Fuels
Group Leader: Alternative Fuels Synthesis
University of Dayton Research Institute
University of Cincinnati
14 May 2013
Generate practical sample quantities of jet boiling range material for evaluation and demonstration
4 Fixed bed reactors with concurrent liquid and gaseous feed
2 Fixed bed FT synthesis reactors and 2 CSTRs available for swap
Continuous off-gas monitoring with on-line GC
Micromeritics ASAP 2020 textural analysis and chemisorption analysis system being installed
Pore size distribution
Metal Catalyst dispersion
Mix-muller for 1-3 kg preparation of extrudable catalyst/binder aggregate
1” laboratory extruder for making shaped catalyst for use in AAFRF or other practical-scale fixed bed reactors reactors
High resolution FTIR with heated multi-path gas cell for trace gas contaminant analysis – NH3,HCN, CO, CO2
Usable for condensed phase research as well
AAFRF SPK properties are nearly identical to other non JP-8 jet fuels
Synthetic approach demonstrated at SPC Lab scale – in house catalysts scaled to multi kg lots
Outstanding performance scalability from lab to AAFRF scale
Fed roughly 2200 gal n-C14 - recovered 1700 gal of mixed C14 isomers
A consolidated 500 gal batch with freezing point of -41.7 °C – meets Jet-A Specification
Isomer distribution is different from a solvent-dewaxed product in a desirable way – multi-branched isomers dominate
Distillation Gradient T90-T10 = 17 °C – meets the narrow boiling target
From concept discussions to fuel delivery in 18 months
A successful campaign and project!
1750 gallons of “CH Crude” delivered for Total Acid Number (TAN) reduction and separation of the Jet-A Specification –compliant fraction
Delivered TAN 140 mg/g
Required reduction to <0.10 mg/g
Distilled fraction to meet Jet-A Specification
Delivered 525 gallons of a theoretical 565 max, >90%
Cumulative TAN 0.005 mg KOH/g – an effective overall conversion of 99.996% !!
First use of a sulfided catalyst in the system
Fuel met all applicable JET-A specifications
Flash point and Freezing point set the bounds on allowable composition
Algae provided by USAF from Phycal production
Output of a Third Frontier development program
Processed ~ 2.5 L of algal oil
Product Alkanes reflect oil composition and a
changing catalyst selectivity with time-on-stream
All methods and catalysts used are readily scalable
Deoxygenated alkane mixture hydro-converted to isomers and cracked products with Pt/US-Y
A Practical Diesel Fuel
Selective removal of n-alkanes improves cold weather flow – Arctic Grade Diesel Fuel
Fitting power law kinetics with the effects of T, concentration of reactants
Rigorous control of all reaction variables to produce reproducible reaction rates allowing parameter extraction
