Biomass Catalytic Upconversion With A Metallic Catalyst Bed Under Radio Frequency Induction Heating, Mohammad Abu-Laban Jan 2016

Biomass Catalytic Upconversion With A Metallic Catalyst Bed Under Radio Frequency Induction Heating, Mohammad Abu-Laban

LSU Master's Theses

This study investigated the thermal performances of platinum particles when coupled on a steel support, under the application of a radio frequency (RF) field. Platinum nanoparticles were reduced on the surfaces of type-316 stainless steel balls, based on published methods of Pt reduction from chloroplatinic acid. Alternatively, 1wt. % Pt/Al2O3 commercial catalyst pellets were mixed with stainless steel balls and investigated for hydro-deoxygenation of pyrolysis oil from pine sawdust biomass. The catalysts were placed inside an electric insulator tube suspended within a looping copper coil connected to the induction heater, and heated at different power levels. An infrared camera was …


Evaluation Of Different Harvesting And Storage Practices: Sweet Sorghum And Energycane, Ana Lucia Amaya Arroyave Jan 2014

Evaluation Of Different Harvesting And Storage Practices: Sweet Sorghum And Energycane, Ana Lucia Amaya Arroyave

LSU Master's Theses

Two attractive potential feed stocks for biofuel production are energycane and sweet sorghum due to the environmental adaptability, sugars concentration and yield. Evaluation and development of harvesting, transportation and storage practices is critical for bringing the production of these crops to industrial levels. This research aims to analyze the supply system of energy crops and evaluate the effect of different harvesting and storage in the yields of the feedstock and the efficiencies of the processes. Harvesting trials were conducted at St. Gabriel, LA for evaluating the feasibility of using energy crops as inputs for ethanol production. The parameters that were …


Ultrasonic Pretreatment Of Energy Cane Bagasse For Biofuel Production, Niyaz Ahamed Methrath Liyakathali Jan 2014

Ultrasonic Pretreatment Of Energy Cane Bagasse For Biofuel Production, Niyaz Ahamed Methrath Liyakathali

LSU Master's Theses

High demand for energy and increasingly expensive petroleum prices led to development of new alternative fuels for transportation, such as bio-ethanol and bio-diesel. Even though a cost reduction in the production of cellulolytic enzymes is occurring, the conversion of plant cellulose into sugars still remains an expensive and slow process. Pretreatment of lignocellulose materials to remove lignin and alter physical/chemical structures significantly improves hydrolysis of cellulose to give high yield of sugars. In this study, ultrasonic pretreatment of energy cane bagasse was used in the presence of ammonia (NH4OH) to enhance the saccharification process by separating lignin, cellulose and hemicellulose …


Rapid Microwave Drying Of Non-Food Agricultural Feedstock For Improved Biofuel Production, Laura A. Picou Jan 2012

Rapid Microwave Drying Of Non-Food Agricultural Feedstock For Improved Biofuel Production, Laura A. Picou

LSU Master's Theses

Due to limited supply of traditional fossil based fuels, and increased interest in air and water quality along with other environmental concerns, there has been a rise in the utilization of biomass based energy sources. Many agricultural materials can be used for the production of biofuels, including materials that are typically underutilized such as sweet sorghum bagasse and otherwise nuisance species such as Chinese tallow tree seeds. The goal of this project was to examine the relationship between the dielectric properties of sweet sorghum bagasse and Chinese tallow tree (CTT) seeds, respectively, and frequency and moisture content; to determine pertinent …


Screening Of Tar Cracking Catalysts For Syngas Produced By Biomass Gasification, Bijeet Mukherjee Jan 2011

Screening Of Tar Cracking Catalysts For Syngas Produced By Biomass Gasification, Bijeet Mukherjee

LSU Master's Theses

The gasification of biomass produces tars and particulates. These tars and particulates create problems in the gasification systems. Tars condense on surfaces at lower temperatures, such as exit pipes and on particulate filters, leading to blockages and clogged filters. Tars also have varied impacts on other downstream processes. Due to these reasons, syngas containing significant concentrations of tars cannot be used in internal combustion engines. Thus the processes through which tars can be removed have been subject to considerable research. The objective of this research was to identify the best catalyst for for down-draft gasifiers, including the LSU AgCenter down-draft …
