Synthesis gas generation by chemical-looping reforming using a Nibased oxygen carrier

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...

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...

Chemical looping combustion process in fixed - bed reactors using ilmenite as oxygen carrier

A process scheme based on a series of fixed-bed reactors is presented as a possible alternative for carrying out the chemical looping combustion of methane at high pressure with ilmenite as oxygen carrier. The oxygen carrier is stationary and it is alternately exposed to reducing and oxidizing atmospheres by means of the periodic switching of the gas feeds (i.e., methane and air, respectively)....

Characterization of a Sol-gel Derived CuO/CuAl2O4 Oxygen Carrier for Chemical Looping Combustion (CLC) and Chemical Looping with Oxygen Uncoupling (CLOU) of Gaseous Fuels

Waste lubricating oil as a source of hydrogen fuel using chemical looping steam reforming

Initial results are presented for the production of hydrogen from waste lubricating oil using a chemical looping reforming (CLR) process. The development of flexible and sustainable sources of hydrogen will be required to facilitate a ‘hydrogen economy’. The novel CLR process presented in this paper has an advantage over hydrogen production from conventional steam reforming because CLR can use ...
