Holtzapple, Mark T.; Davison, Richard R.; Nagwani, Murlidhar (United States. Patent and Trademark Office; Texas A&M University. Libraries, 1997-12-02)Lignocellulose-containing materials are treated with lime (calcium hydroxide) and water at a relatively high temperature and for a certain period of time under certain conditions. The process variables were: lime loading ...
-
Watanawanavet, Somsak (2009-05-15)Research was performed to optimize the high-efficiency jet ejector geometry by varying motive velocities from Mach 0.50 to 3.25, and mass flow ratio from 0.02 to 100.0. The high-efficiency jet ejector was simulated by ...
-
Han, Joseph H. (1998)With literally tons of biomass produced annually, a process that uses this waste as a feedstock would help reduce the problem of disposal. The MixAlco process is one that does just that. It converts biomass through anaerobic ...
-
Gay, Sebastien Emmanuel (2009-05-15)Road and rail vehicles and aircraft rely mainly or solely on friction brakes. These brakes pose several problems, especially in hybrid vehicles: significant wear, fading, complex and slow actuation, lack of fail-safe ...
-
Fu, Zhihong (2009-05-15)With the inevitable depletion of the petroleum supply and increasing energy demands in the world, interest has been growing in bioconversion of lignocellulosic biomass (e.g., sugarcane bagasse). Lignocellulosic biomass ...
-
Hong, Jeong-Hwa (Texas A&M University. Libraries, 1988)Bioconversion of cellulose has great potential for applying large quantities of fermentable feedstocks which can be converted to fuels and commodity chemicals. To achieve maximum conversion of celluose in enzymatic hydrolysis ...
-
Vishwanathappa, Manohar D. (Texas A&M University, 2005-08-29)The ability to produce potable water economically is the primary focus of seawater desalination research. There are numerous methods to desalinate water, including reverse osmosis, multi-stage flash distillation, and ...
-
Lubis, Mirna R. (2010-07-14)The ability to produce potable water economically is the primary purpose of seawater desalination research. Reverse osmosis (RO) and multi-stage flash (MSF) cost more than potable water produced from fresh water resources. ...
-
Asadi, Peyman (2009-05-15)This dissertation contains the results of research conducted on the design and control characterization of a Switched Reluctance Generator (SRG) for maximum output power. The SRG is an attractive solution to the increasing ...
-
Walsh, Daniel A. (1996)The liquid piston Stirling engine is an environmentally conscious technology developed to replace the electric heat pump and the gas furnace. Dr. Holtzapple's innovative modifications to existing Stirling engine technology ...
-
Falls, Matthew David (2011-10-21)At present, the United States generates biofuels (ethanol) from corn grain. Unfortunately, low crop yields and limited growth regions result in limited availability. Furthermore, the use of staple food crops for ethanol ...
-
Xu, Xin (Texas A&M University, 2008-10-10)The MixAlco process, a proprietary technology owned by Texas A&M University, converts biomass (e.g., municipal solid waste, sewage sludge, paper, agricultural residues, and energy crops) into usable chemicals (e.g., ...
-
Golub, Kristina (2012-10-19)Using mixed-culture fermentation, the carboxylate platform produces carboxylic acids, which are chemically converted into chemicals and fuels. To optimize the mixed-acid fermentation, different bioreactor configurations ...
-
Wu, Haoran (2018-11-29)The carboxylate platform is a biomass-to-energy process that converts biomass into hydrocarbon fuels or chemicals. The mixed-acid fermentation is the essential unit of the process that uses mixed cultures of microorganisms ...
