Hypercrosslinked polymers (HCPs) synthesized by copolymerisation of p-dichloroxylene (p-DCX) and 4,4′-bis(chloromethyl)-1,1′-biphenyl (BCMBP) constitute a family low density porous materials with excellent textural development. Such show microporosity mesoporosity exhibit Brunauer–Emmett–Teller (BET) surface areas up to 1970 m2 g−1. The CO2 adsorption capacity these was evaluated using thermogravimetric analyser (atmospheric pressure tests) high-pressure magnetic suspension balance (high...
Different carbon materials were tested as precursors for the production of CO2 adsorbents. The chemical modification surface prepared adsorbents was studied by means three different approaches: impregnation with amines, electrophilic aromatic substitution, and heat treatment in presence ammonia. samples chemically characterized porous texture evaluated from N2 adsorption isotherms at −196°C. capacities 25 100°C a thermogravimetric analyzer. In general, incorporation basic nitrogen...
The feasibility of producing activated carbon (AC) from real Household Mixed Plastic Waste (HMPW) comprising LDPE, HDPE, PP, PS, and PET for capture via direct carbonisation followed by microwave-assisted or conventional thermally assisted chemical activation was investigated. A procedure adopted to assess the impact on CO2 capacity resulting AC using both a lower temperature (400 °C vs. 700 °C) shorter duration (5 120 mins) than that required activation. results obtained showed yield 71 78%...
Post-combustion carbon capture is a key component of the fight against global warming and climate change. Amine stripping currently leading post-combustion technology, indeed employed at World’s first only commercial scale project applied to power plant, Boundary Dam, Canada. Normally, regeneration spent amine solution achieved by with hot pressurized steam, around 120–140 °C 1–2 bar. However, production these conditions costly leads significant degradation amine. Moreover, size equipment,...
This work presents an economic and simple method to manufacture low cost, but effective adsorbents for CO2 capture through impregnating DETA a porous silica gel. The results have demonstrated that the cost gel impregnated by molecular-weight amine is stable very well at temperature up 130 °C. developed adsorbent has fast adsorption kinetics can be regenerated temperature. will significantly reduce energy used desorb CO2, therefore penalty. effect of loading on textural properties, thermal...
Using lignocellulosic biomass-based sorbents for CO2 capture potentially offers a sustainable solution to combatting global warming effects and preserving the environment through reduction of greenhouse gas emissions, mainly carbon dioxide. In this work, activated carbons were produced from microcrystalline cellulose using simple, moderate physical activation procedure. Activations at 10, 20 30% burn-off along with original biochar characterised their chemical properties, ability by...
Wastewater treatment often enables discharge into natural water bodies, but for effective reuse, further is essential. Membrane processes provide a precise solution yet face limitations due to fouling and organic material adsorption, impacting their performance. This study focuses on synthesising ultrafiltration membranes using non-solvent-induced phase separation. These are produced from Polyethersulfone/N,N′-dimethylacetanamide (PES/DMA) with varying concentrations of three commercial...
Microwave (MW) heating is proposed as a method to transform polyethylene terephthalate (PET) into porous adsorbents. The yield, textural properties, and CO2 uptake of the PET-derived adsorbents irradiated at different durations (3 – 35 min) 400 °C were assessed. MW activation time influenced both physical properties capacities resulting yield decreased with time, but surface area, total pore volume, micropore all increased before declining. optimal sample (produced 5 min time) showed...
The optical constants together with the magneto-optical Voigt of several phthalocyanine (Pc) and methoxy functionalized tetraphenylporphyrin (TMPP) thin films prepared on silicon substrates are presented. materials investigated MePc Me = Fe, Co, Ni, Cu, Zn MeTMPP Ni.
