In the present work, we explore use of steam in CaCO3 calcination step Calcium Looping process devised for thermochemical energy storage (CaL-TCES). Steam produces a double benefit: firstly, it fastens calcination, allowing reduction temperature needed to attain full short residence times, as those required practice, resulting savings. This behaviour is justified on basis kinetics study results obtained from non-parametric kinetic analysis, which demonstrate that presence during can reduce...

Abstract Diethyl l ‐tartrate (DET) is used as a biobased plasticizer for poly(lactide) (PLA) formulations with improved ductile properties without compromising biodegradation. Different weight percentages (wt.%) of DET in the 0–50 wt.% range are added to PLA by melt compounding and subsequently processed injection molding. The effect on mechanical, thermal, thermo‐mechanical, morphology, biodegradation, crystallinity studied. Addition 20 leads noticeable increase elongation at break up...

Abstract This study demonstrates the potential of different cinnamate esters, namely methyl trans‐cinnamate (MC), isobutyl (IBC), allyl (AC), and ethyl (EC), as environmentally friendly plasticizers for polylactide (PLA). Plasticized PLA formulations with a constant nominal wt% 20 each plasticizer are compounded in twin‐screw co‐rotating extruder subsequently processed by injection molding. The results show exceptional plasticization efficiency AC an increase elongation at break from 3.9%...

This study explores the effect of steam addition during carbonation on multicyclic performance limestone under calcium looping conditions compatible with (i) CO2 capture from postcombustion gases (CCS) and (ii) thermochemical energy storage (TCES). Steam injection has been proposed to improve uptake capacity CaO-based sorbents when calcination loops are carried out in CCS conditions: at moderate temperatures (∼650 °C) low concentration (typically ∼15% atmospheric pressure). However, recent...

Large-scale thermochemical energy storage (TCES) is gaining relevance as an alternative to current thermal systems in Concentrated Solar Power plants. Among the different systems, reversible reaction between CaO and CO2 stands out due wide availability low cost of raw material: limestone. Direct solar absorption media would improve efficiency solar-to-thermal reduced transfer barriers, but optical CaCO3 poor. In this work, we propose use a Ca-rich calcarenite sedimentary rock so-called...

The use of waste to capture CO

Cigarette butts (CBs) are one of the most common types litter in world. Due to toxic substances they contain, waste generated poses a harmful risk environment, and therefore there is an urgent need for alternative solutions landfill storage. Thus, this work presents possible revalorization material, which implies interesting environmental benefits. CBs were used as sacrificial templates preparation CaO-based materials by impregnation with calcium magnesium nitrates followed flaming...

This study investigates the viability of cinnamic acid derivatives as alternative plasticizers for polyvinyl chloride (PVC) films by addressing concerns about conventional phthalate-based options that pose health and environmental risks. By theoretical modeling, this research evaluates compatibility between various acid-based PVC matrix, which suggests their potential effectiveness. Additionally, incorporation these notably enhances tensile properties films, particularly in terms ductility...

New composite materials were developed with poly(lactide) (PLA) and Posidonia oceanica fibers through reactive extrusion in the presence of dicumyl peroxide (DCP) subsequent injection molding. The effect different amounts methyl trans–cinnamate (MTC) on mechanical, thermal, thermomechanical, wettability properties was studied. results showed that generated disruptions PLA matrix, causing a decrease tensile mechanical an impact strength due to stress concentration phenomenon. Reactive DCP...

In recent years, the implementation of CO2 capture systems has increased. To reduce costs and footprint processes, different industrial wastes are successfully proposed for capture, such as gypsum from desulfurization units. This undergoes an aqueous carbonation process producing added-value solid material that can be valorized. this work, panels have been manufactured with a replacement (5 20%) commercial all compositions kept water/solid ratio constant (0.45). The density, surface...

In this study, a new composite material is developed using semi bio-based polypropylene (bioPP) and micronized argan shell (MAS) byproducts. To improve the interaction between filler polymer matrix, compatibilizer, PP-g-MA, used. The samples are prepared co-rotating twin extruder followed by an injection molding process. addition of MAS improves mechanical properties bioPP, as evidenced increase in tensile strength from 18.2 MPa to 20.8 MPa. reinforcement also observed thermomechanical...

The use of plasticizers usually has a beneficial effect on the ductile properties polymers due to reduction in interaction polymer chains. As result this reduced interaction, there is also tensile strength material up 20.3 MPa. To improve and plasticizer without affecting ductility material, potential migration, reactive extrusion (REX) process proposed research, by using several organic peroxides poly(lactide)-dibutyl itaconate (DBI) plasticized formulations. Test specimens are obtained...
