Kym Arcuri, Process BTL/GTL and CTL Technology Advisor PhD

Dr. Arcuri has over 35 years in the petrochemical process area.  Specifically, he has over 25 years in the areas involving syngas generation, FT synthesis and the upgrading of FT liquids into jet, diesel and lube base oil.  With respect to syngas generation, Dr. Arcuri helped developed autothermal and steam methane reforming at Exxon, Syntroleum and Emerging Fuels Technology and has extensive experience with most commercial technologies.  Over his career Dr. Arcuri has direct experience with biomass gasification and pyrolysis as an independent contractor.  Dr. Arcuri designed several syngas clean up systems which permitted all types of syngas to achieve the desired quality for catalytic processing.  With respect to hydroprocessing, Dr. Arcuri has over 10 years in evaluating and comparing commercial converting FT and pyrolysis liquids into fully specified fuel or base oil products.


Over the past 15 years, Dr. Arcuri has developed over 50 integrated process models associated with GTL, BTL and CTL processes which served as the basis for FEL-2 and FEL-3 evaluations.  The combination of a strong R&D background and practical engineering experience provides a solid foundation to evaluate potential technologies and integration into commercial production facilities.

Robert Freerks, Synthetic Fuels, Waxes and Lubricants Technology Advisor PHD

His career has always been centered on the chemistry of fuels, lubricants and specialty chemicals.  Chevron provided the opportunity to develop skills in produce chemistry and commercial process development where a number of new chemicals were developed for the lubricant additives product line of Chevron Oronite.  He expanded into formulation of finished products for Chevron Global Lubricants working on Delo 400 and other Heavy Duty Diesel Engine Oils as well as synthetic lubricants.  The next phase of learning was to formulate additive packages for all engine oil products for Chevron Oronite where products were developed that moved Oronite from last to first in additive sales in the Asia-Pacific region. 


After 18 years at Chevron, he moved to develop synthetic base oils at Syntroleum and also initiated the work on synthetic jet fuel blend components (SPK jet fuel) with the Department of Defense.  He worked with the Office of the Sec. Def. Undersecretary for Science and all branches of the Military on developing SPK jet fuel culminating in the first flight of SPK jet fuel in a B-52 in 2006.  I spent much of my time at Syntroleum working on production of synthetic base oils from F-T wax and brought this technology to the point where a full EPC contract for plant construction was executed with RWE engineering. Economic events of the early 2000 time frame prevented funding of this project.


After Syntroleum collapsed, he spent 6+ years at Rentech continuing development of synthetic fuels, lubricants and base oils.  In 2009, SPK jet fuel blend component was fully certified by ASTM for use in all commercial jet fuel (ASTM D1655 and D7566).  He participated in the ASTM activities involved in completing these specifications from the beginning.
