Initially installed at IPST\u2019s Industrial Engineering Center on 14th Street, it was dismantled and moved again to Georgia Tech\u2019s new NIST-funded Carbon Neutral Energy Solutions (C-NES) Laboratory.\u0026nbsp; The PEFR is designed to create a controlled environment of temperature, pressure, gas composition, and residence time, allowing fundamental and applied research in pyrolysis, gasification, and combustion of solid fuels.\u0026nbsp;\u0026nbsp; There are perhaps ten similar reactors world-wide, owned by universities or government research laboratories, and IPST\u2019s is by far the largest allowing long fuel particle residence times\u2014on the order of 30 seconds.\u0026nbsp; Initially the PEFR was used to study pyrolysis and gasification of black liquor (after being dried and ground into a powder).\u0026nbsp; Years later its use was expanded into research on a variety of agricultural and forest biomasses, mill sludge, and coal.\u003C\/p\u003E\u003Cp\u003ESince 2001, Dr. Sinquefield has been the principal investigator overseeing the PEFR, and a smaller atmospheric pressure Laminar Entrained Flow Reactor (LEFR).\u0026nbsp;\u0026nbsp;\u0026nbsp; These reactors are ideally suited for taking reaction rate data to build kinetic models as well as other parametric studies.\u0026nbsp; Considerable work was done to develop kinetic models for pressurized black liquor gasification.\u0026nbsp; The PEFR was also used to study and develop titanate and borate direct causticizing chemistries to perform the causticizing process simultaneously during black liquor gasification.\u0026nbsp;\u0026nbsp; Current PEFR research includes fundamental studies of pyrolysis and gasification of loblolly pine, switchgrass, bagasse, corn stover, and lignite coal.\u003C\/p\u003E\u003Cp\u003EDr. Sinquefield\u2019s other past and present research projects include:\u003C\/p\u003E\u003Cul\u003E\u003Cli\u003EDevelopment of a sulfur-tolerant CO\u003Csub\u003E2\u003C\/sub\u003E\u0026nbsp;sorbent (patent pending) that works at gasifier temperatures.\u0026nbsp; It is central to a process that allows high yields of hydrogen to be produced without the need for expensive water-gas-shift catalysts and for CO\u003Csub\u003E2\u003C\/sub\u003E\u0026nbsp;to be captured for sequestration.\u003C\/li\u003E\u003Cli\u003ECreation of a computer model for predicting precipitate (salt) species from concentrated non-ideal electrolyte solutions.\u0026nbsp; The primary application was to predict black liquor evaporator scale composition.\u003C\/li\u003E\u003Cli\u003EDesign of a portable apparatus for evaluating commercial anti-scaling additives on site in the mill (United States Patent 6,978,663).\u0026nbsp;\u0026nbsp; The impetus was to test and benchmark additives used in black liquor heaters and evaporators, and do so in a matter of hours or days.\u0026nbsp; Currently, such mill trials take several weeks to perform.\u0026nbsp; The device can be used in any hot liquid process stream that is subject to scale formation related to heat transfer.\u003C\/li\u003E\u003C\/ul\u003E\u003Cp\u003EDr Sinquefield completed his PhD in Chemical Engineering in 1998 at Oregon State University.\u0026nbsp;
