Heat of adsorption in the fly ash zeolite – CO2 system at dynamic conditions
Zgureva D., (Corresponding) Boycheva S., Marinov I., Miteva S., Asenov A.
Topic:
Climate change mitigation and adaptation
The global warming represents one of the main world problems in the recent decades as it is considered that electricity production by coal burning is responsible for 40 % of the total CO2 emissions. The post-combustion capture of CO2 based on physical adsorption has the highest potential for...Read more

Comparative studies of the equilibrium adsorption of CO2 onto coal ash zeolites Na-X and Na-Ca-X
(Corresponding) Boycheva S., Marinov I., Miteva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
Coal-fired Thermal Power Plants (TPPs) are the main source of greenhouse gas emissions in the atmosphere, but they also generate huge amounts of solid by-products, including fly ash (FA). A modern strategy for sustainable energy production is to improve the ecology of the TPPs by developing...Read more

Coal ash zeolite as a self-catalytic-chemisorption system for conversion of carbon dioxide to hydrocarbons
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
At present, the developments of sustainable carbon capture technologies are of the main scientific and technological priority required to mitigate the over generation of greenhouse gases. Three CO2 clean energy production approaches have been outlined: pre-combustion capture, oxy-fuel combustion...Read more

Transferring the Carbonation of Biomass Bottom Ash from Batch to Continuous Operation
(Corresponding) Schnabel K., Brück F., Pohl S., Weigand H.
Topic:
Mineral carbonation of alkaline waste materials
Biomass incineration residues may be used for CO2 capture and storage by carbonation of waste-borne metal hydroxides. Moist carbonation of these ashes can be performed under mild conditions (ambient pressure and temperature) and accelerated by using a CO2-rich gas. The process requires the wetting...Read more

Studies on the CO2 adsorption mechanism of Na-X and Na-Ca-X coal fly ash zeolites
(Corresponding) Boycheva S., Lazarova H., Zgureva D., Popova M.
Topic:
Climate change mitigation and adaptation
Coal fly ash zeolites (CFAZ) of Na-X and Na-Ca-X types were synthesized using as raw materials fly ashes generated by the combustion of lignite from various deposits with low and medium limestone content. It has been found that CFAZs with higher calcium content superior those containing less...Read more
Studies on the CO2 adsorption onto coal fly ash zeolites at elevated pressures
(Corresponding) Boycheva S., Zgureva D.
Topic:
Climate change mitigation and adaptation
Coal fly ash zeolites (CFAZs) of Na-X type were prepared by ultrasonic-assisted double stage fusion-hydrothermal synthesis from lignite coal fly ash at two different fusion temperatures 550 and 800 C. The detailed surface analyses were performed experimentally using N2 physisorption technique and...Read more
Upgrading from biogas to biomethane is currently growing in Europe for economical and sustainable aspects. To date different treatments are proposed to upgrade biogas to a higher fuel standard. Among these, physico-chemical treatments are spreading widely in the biogas technology market...Read more

Topic:
Circular economy and industrial symbiosis
Under the Paris agreement, Malaysia has set its target of reducing greenhouse gas emissions by 45% by 2030 (35% of which is on an unconditional basis), having 2005 as the base year. Carbon capture and utilization, together with an increased use of renewable energy sources, will be one of the main...Read more
