Life Cycle Assessment of Natural Gas-based Chemical Looping for Hydrogen Production

Biomass pyrolysis oils for hydrogen production using chemical looping reforming

This study considers the feasibility of using highly oxygenated and volatile pyrolysis oils from biomass wastes as sustainable liquid fuels for conversion to a hydrogen-rich syngas using the chemical looping reforming process in a packed bed. Pine oil and palm empty fruit bunches oil‘EFB’were investigated with a Ni/Al2O3 catalyst doubling as oxygen transfer material (OTM). The effect of molar s...

Investigation of Sour Natural Gas Decomposition in a Nozzle-type Solar Reactor for Hydrogen Production

Investigation on life cycle assessment of lead and zinc production

Lead and zinc production is one of the main predisposing factors of excessive greenhouse gases emissions, air pollution and water consumption. In this paper, the environmental problems of lead and zinc production in Calcimin plant are expressed and life cycle assessment of this plant is assessed. The data regarding the amount of induced global warming and pollution, acidification, and depletion...

Life-Cycle Assessment of Environmental Effects on Rapeseed Production

In recent years, increasing the awareness on the environmental problems, especially global warming, has increase the concerns about the impact of emissions on the global climate. The current study was conducted to evaluate and analyze the environmental effects of rapeseed production in the form of life cycle using SimaPro software with the aim concentration on climate changes and impact of acid...

Optimization of Hydrogen Production by Chemical-Looping Auto- Thermal Reforming Working with Ni-based Oxygen-Carriers

Chemical-Looping auto-thermal Reforming (CLRa) is a new process for hydrogen production from natural gas that uses the same principles as Chemical-Looping Combustion (CLC). The main difference with CLC is that the desired product is syngas (H2 + CO) instead of CO2 + H2O. For that, in the CLRa process the air to fuel ratio is kept low to prevent the complete oxidation of the fuel. The major adva...
