1. Lignocellulosic Ethanol Production: Studies on Sugarcane Bagasse, Paja Brava, Wheat Straw, Quinoa Stalks and Curupaú
Sammanfattning : Lignocellulosic biomass refers to plant material that is composed mainly of cellulose, hemicellulose and lignin. These materials are today of large interest to researchers in the field of biofuel and bioenergy. LÄS MER
2. Experimental and Modeling Studies of Sulfur-Based Reactions in Oxy-Fuel Combustion
Sammanfattning : Oxy-fuel combustion is a technology for CO2 capture that is suitable for large-scale, coal-fired power plants. In this system, the combustion air is replaced by a mixture of O2 and recycled flue gases, so as to enrich for CO2 in the flue gas. LÄS MER
3. Process Development of Bioethanol Production from Wheat and Barley Residues Steam Pretreatment and SSF
Sammanfattning : Bioethanol has received increasing attention as an alternative to petrol due to the current dependency on supplies from other countries and due to the increased concentration of the greenhouse gas carbon dioxide in the atmosphere. In this thesis, the development of 2nd generation production processes for bioethanol production from the lignocellulosic part of biomass is discussed. LÄS MER
4. Hydrolysis of by-products from cereal kernels for improved ethanol production
Sammanfattning : This work deals with the hydrolysis of lignocellulosic agricultural residues, by means of combined pretreatment and enzymatic hydrolysis, to be used for ethanol production. Four agricultural by-products, i.e. LÄS MER
5. Process Development for Extraction and Separation of In and Y from Discarded Flat Panel Displays
Sammanfattning : From the time of their invention in the 1970s, flat panel displays (FPDs) have slowly become the most used type of displays in televisions, computers, and cell phones. A major subgroup of FPDs is lLiquid crystal displays (LCDs). LÄS MER
