1. Fischer-Tropsch synthesis from bio-syngas models over cobalt and cobalt-iron alumina supported catalysts
Abstract : Fischer-Tropsch (FT) synthesis is a process in which synthesis gas (syngas), a mixture of H2 and CO, is converted into long chain hydrocarbons mainly over Co- or Fe-based catalysts. The FT synthesis requires an H2/CO molar ratio (usage ratio) of approximately 2.1 above the catalyst surface. If the inlet syngas H2/CO ratio is less than 2. READ MORE

2. Improved Energy Efficiency and Fuel Substitution in the Iron and Steel Industry
Abstract : IPCC reported in its climate change report 2013 that the atmospheric concentrations of the greenhouse gases (GHG) carbon dioxide (CO2), methane, and nitrous oxide now have reached the highest levels in the past 800,000 years. CO2 concentration has increased by 40% since pre-industrial times and the primary source is fossil fuel combustion. READ MORE

3. Assessing the Integration of Biomass Gasification-Based Production of Chemicals — Case Study of an Oxo Synthesis Plant
Abstract : The chemical industry sector is energy-intensive and highly dependent on fossil feedstock. The primary long-term option to reduce fossil feedstock dependence and greenhouse gas (GHG) emissions is to switch to renewable feedstock. READ MORE

4. CO2 Separation - from Aqueous Amine Solvent to Ionic Liquid-based solvent
Abstract : CO2 separation is one of the most important roles in CO2 mitigation target as many human production activities (e.g., cement, iron and steel, and biogas productions) cause CO2 emissions. The solvent-based absorption is the most mature technology for CO2 separation, where different solvents capture CO2 either in chemical or physical absorptions. READ MORE

5. Sustainable valorization of Biomass into Syngas/H2 via Biocarbon catalyst
Abstract : Environmental issues stemming from the rapid growth in global energy demand and carbon dioxide emissions require urgent resolutions. Biomass represents a viable alternative for displacing fossil fuels, as its energy can be converted into electricity, heat, fuels, and chemical precursors, thus substituting petrochemicals. READ MORE
