DOE/METC - University of Massachusetts - Review of the thermodynamic, physical - chemical & detailed design issues for modeling fluid bed coal gasifiers.


Hydrocarbon Research, Inc. - Performed analysis of fluidization aspects of a commercial scale dynacracking reactor prototype. U. S. patent coverage was obtained for HRI for this novel reactor configuration. Authored internal reports on dynacracking reactor design, alternative configuration analysis, oxygen injection and state of the art reviews on fluidized packed beds and regimes of fluidization. Developed cold flow test programs.


Systems, Science and Software - Prepared state of the art survey on high temperature fluidization and ash agglomeration which resulted in the identification of a novel approach to the determination of incipient fluidization of sinterable solids. Assisted in population balance model preparation and data analysis related to coal gasifiers.


TRW Energy Sys. Group - Performed fluidization analysis of ICGG-Cogas Coal Liquefaction/Gasification process.


Post Doctoral - Clean Fuels Institute/CUNY - Research Engineer

Authored five (5) technical articles on coal conversion technology. Formulated and evaluated reactor configurations for flash hydrogenation of coal.  Provided consulting services to HRI on CUNY subcontract during first phase fast fluid bed (FFB) gasifier operations. 


Union Carbide Corporation - Senior Engineer

Developed and demonstrated, in a pilot unit, successful techniques for injection of agglomerating coals into a fluid bed hydrocarbonizer at commercially viable conditions.  This work has resulted in two patents relating to the injection, dispersion and operation of fluid beds while processing caking coals.  Operated a geometrically similar cold model of the mini-plant hydrocarbonizer and collected fluidization and attrition characteristics of char and coal.


Chemical Construction Corporation - Senior Process Engineer 

Performed engineering planning and analysis for Clean Boiler Fuel Demonstration Plant Program.   Identified and planned commercial plant subsystem alternative/feasibility studies.  Developed design manual "Hydrocarbonization Reactor Design Report".  Prepared test programs for demonstration of caking coals injection into a riser and into a turbulent bed.  Developed in-house test plans for cold model study of solids transport, injection, fluidization and recirculation.  Acted as technical interface with subcontractors for numerous test programs.
