Coal and biomass combustion with CO2 capture by CLOU process using a magnetic Fe-Mn-supported CuO oxygen carrier
نویسندگان
چکیده
The Chemical Looping with Oxygen Uncoupling (CLOU) process is a derivative technology of the Combustion (CLC) for combustion both renewable and non-renewable solid fuels. present work studies CO2 capture efficiency burning coal or biomass using single Cu-based oxygen carrier magnetic properties as an carrier. two different coals three biomasses was performed in 1.5 kWth CLOU continuously operated unit 36 h. were also studied after its separation from ashes. Complete fuel to H2O achieved all cases. For coals, increased reactor temperature, reaching values 97% at 900 °C. same increase obtained biomasses. highest pine sawdust, which value 93%, followed by almond shell (86%) olive stone (80%) reactivity remained constant use continuous one small attrition jet index (AJI) value. used particles found still be fresh particles, fines highly magnetic. Values higher than 99% reached. It therefore proven that elutriated plant could easily separated ash.

CO2 Capture Performance Using Biomass-templated Cement-supported Limestone Pellets
Synthetic biomass-templated cement-supported CaO-based sorbents were produced by granulation process for high-temperature post-combustion CO2 capture. Commercial flour was used as the biomass and served as a templating agent. The investigation of porosity showed that the pellets with biomass or cement resulted in enhancement of porosity. Four types of sorbents containing varying proportions of ...

Chemical-Looping Combustion and Gasification of Coals and Oxygen Carrier Development: A Brief Review
Chemical-looping technology is one of the promising CO2 capture technologies. It generates a CO2 enriched flue gas, which will greatly benefit CO2 capture, utilization or sequestration. Both chemical-looping combustion (CLC) and chemical-looping gasification (CLG) have the potential to be used to generate power, chemicals, and liquid fuels. Chemical-looping is an oxygen transporting process usi...
متن کاملNOx Control in coal combustion by combining biomass co-firing, oxygen enrichment and SNCR
There has been renewed interest in evaluating the effect of biomass co-firing on the multi-pollutant control system such as Selective Non-catalytic Reduction (SNCR) and oxygen enrichment. Emissions savings have been attained by combining SNCR and biomasscoal co-combustion under various oxygen enriched staged air levels. Biomasses with higher tendency of generating CO produced better reduction i...
