Microalgae bio-fixation efficiency of carbon dioxide through innovative planar photobioreactor

Costantino V., Carone M., (Corresponding) Riggio V., (Corresponding) Derossi C., Alpe D., Occhipinti A., Zanetti M.
Topic: 
Climate change mitigation and adaptation
The high anthropogenic activity of recent centuries has led to an urgent need to improve CO2 capture and sequestration technologies. In this context, microalgae systems have gained importance, thanks to their high photosynthetic efficiency and the many applications to which they can be destined...Read more

Experimental studies of the course of CO2/CH4 exchange sorption on hard coal subjected to confining pressure.

(Corresponding) Skoczylas N.
Topic: 
Gas emissions control and utilization
Studies were carried out on exchange sorption of CO2/CH4 on four samples of hard coal differing in the degree of coalification. The samples were subjected to various confining pressures in the range from 1.5 MPa to 30 MPa. The author's conception of the measuring apparatus made it possible to...Read more

Laboratory studies of coal permeability under conditions corresponding to in situ, in terms of assessing the possibility of underground CO2 storage with CH4 recovery

(Corresponding) Kudasik M.
Topic: 
Gas emissions control and utilization
Investigations of processes accompanying the exchange sorption of CO2/CH4 under confining pressure in the range of 1.5 MPa to 30 MPa have been carried out. The research was carried out on innovative apparatus for testing filtration, sorption and CO2/CH4 exchange sorption processes under isobaric...Read more

CO2 Utilization for Preparation of Carbon Nanostructures

(Corresponding) Giannakopoulou T., Plakantonaki N., Vagenas M., Papailias I., Boukos N., Todorova N., Trapalis C.
Topic: 
Gas emissions control and utilization
The CO2 conversion to valuable materials is a challenging way to manage pollution problems. In the present work, CO2 was used as a feedstock to synthesize solid carbon nanostructures by employing a simple magnesiothermic reduction reaction under constant gas flow in a tube furnace. It was shown...Read more

Using CO2- induced magnesium carbonate as environmental friendly additives for petroleum decontamination sandy soils

(Corresponding) Abdeh Keykha H., Mavroulidou M., Mohamadzadeh H.
Topic: 
Soil and groundwater contamination and remediation
Chemical pollutants, including petroleum contaminations causes soil pollution due to improper transportation, leakage, or storage. Several methods for soil decontamination have been presented according to the type of soil and their level of pollution. In choosing the appropriate method and...Read more

Direct upgrading of biogas produced by anaerobic digestion: preliminary results at laboratory scale

Bonaccorsi L., Fazzino F., Fotia A., Malara A., Pedullà A., (Corresponding) Calabrò P.
Topic: 
Environmental biotechnology and bioenergy
The present study investigated, at laboratory scale, the possibility of achieving biogas upgrading with a single step of treatment, namely without involving any pre- or post-treatment or multiple stage recirculation. In this respect, three commercial molecular sieves (i.e., Honeywell 13X, 4A, and...Read more
