1. Investigation of Ilmenite from Oxygen Carrier Aided Combustion: Sulfur Interactions and Recovery of Elements
Sammanfattning : Oxygen- Carrier- Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste in fluidized-bed (FB) units. In OCAC the conventional bed material silica sand is replaced by an oxygen carrier (OC). Replacing the bed material with an OC has many advantages. LÄS MER
2. Removal and Recovery of Metals from Municipal Solid Waste Incineration ashes by a Hydrometallurgical Process
Sammanfattning : Municipal Solid Waste Incineration (MSWI) fly ash contains significant amounts of leachable metals, and is therefore considered to be a hazardous waste. The increased amounts of fly ash generated cause environmental issues, management costs and accumulation of valuable metals in landfills. LÄS MER
3. Steam Explosion of Wood
Sammanfattning : The rising price of petroleum and environmental concerns regarding CO2 emissions has increased interest in alternative renewable resources. Biomass can be considered as an excellent alternative raw material. A biorefinery uses biomass and produces fuel, energy and value-added chemicals. LÄS MER
4. Chemical and Biochemical Biorefineries in Kraft Pulp Mills – Process Integration and Economics for Three Concepts
Sammanfattning : Some of the advantages of integrating biorefinery concepts with kraft pulp mills are that the utility system can be shared and that mass and energy streams can be exported from the pulp mill to the biorefinery or vice versa. These measures may result in lower investments and operating costs for the biorefinery compared with stand-alone operations. LÄS MER
5. Hybrid Solvents based on Ionic Liquids/Deep Eutectic Solvents for CO2 Separation : Experiments, Modeling, Process Simulation and Evaluation
Sammanfattning : CO2 separation plays a vital role in reducing CO2 emissions to combat climate change, in which solvent-based absorption is widely considered the most promising technology. Many conventional chemical and physical solvents have been introduced for CO2 separation, still facing challenges. LÄS MER
