Downdraft Gasifier with Internal Cyclonic Combustion Chamber
Patil, Krushna N.; Huhnke, Raymond L.; Bellmer, Danielle D.; Board of Regents/Oklahoma State University and the A & M Colleges (U.S. Patent and Trademark Office, 2014-02-25)A downdraft gasifier is disclosed. The gasifier includes a biomass section that accepts and stirs raw biomass materials, a pyrolysis and tar cracking section having an inner cylinder for receiving biomass and an outer ... -
Effects of biomass feedstocks and gasification conditions on the physiochemical properties of char
Qian, Kezhen; Kumar, Ajay; Patil, Krushna N.; Bellmer, Danielle; Wang, Donghai; Yuan, Wenqiao; Huhnke, Raymond Leroy (MDPI, 2013-08-06)Char is a low-value byproduct of biomass gasification and pyrolysis with many potential applications, such as soil amendment and the synthesis of activated carbon and carbon-based catalysts. Considering these high-value ... -
Effects of Torrefaction and Densification on Devolatilization Kinetics and Gasification Performance of Switchgrass
Sarkar, Madhura (Oklahoma State University, 2013-12-01)The overall goal of this research was to investigate effects of pretreatments (torrefaction at 230 and 270°C, densification, and combined torrefaction and densification) on biomass properties, devolatilization kinetics ... -
Experimental investigation and simulation of a fluidized-bed gasifier using switchgrass
Sharma, Ashokkumar Misarilal (2013-12)The overall goal of this research was to improve and optimize yield and composition of syngas generated from biomass gasification using an autothermal lab-scale fluidized-bed gasifier, and to develop a biomass gasification ... -
Synthesis and Evaluation of Novel Biochar-based and Metal Oxide-based Catalysts for Removal of Model Tar (Toluene), Nh3, and H2s from Simulated Producer Gas
Bhandari, Pushpak Nandan (Oklahoma State University, 2012-12-01)Gasification is a thermochemical conversion process in which carbonaceous feedstock is gasified in a controlled atmosphere to generate producer gas. The producer gas is used for production of heat, power, fuels and chemicals. ... -
Wet scrubbing of biomass producer gas tars using vegetable oil
Bhoi, Prakashbhai Ramabhai (2014-05)The overall aims of this research study were to generate novel design data and to develop an equilibrium stage-based thermodynamic model of a vegetable oil based wet scrubbing system for the removal of model tar compounds ...
