Modified Carbonized Rice Husk as Low-Cost CO2 Adsorbent: Perspectives and Possible Improvements

Abstract

The international scientific community in the recent years deserves great attention to the problem of greenhouse gases emissions into the atmosphere. Particular importance was given to the development of CO 2 capture and storage strategies. This work investigates the possibility to use carbonized rice husk as a low cost starting materials for the production of СО 2 sorbents. The performances toward CO 2 capture of materials based on rice husk were carried out in a static microreactor showed high efficiency up to 60% with respect to the previously studied carbon-based sorbents.

Nanocomposite material like advanced sorbent materials for carbon dioxide capture

“…Following the same approach with ferromagnetite (FM) reported in [17,18] a set of fi ve cRH/FM composites was produced by varying the amount of cRH from 0 to 100 wt.%. Starting form the procedure reported in [19] for the preparation of magnetite nanoparticles (nFM) in presence of a surfactant (TMAOH), a new approach was developed for the production of cRH/nFM composites by varying the amount of cRH from 0 to 100 wt.%.…”

“…When RH is carbonized under controlled conditions its surface area and porosity increase making carbonized RH a good candidate for CCS approaches [12][13][14][15][16]. The carbonization of raw RH was performed in an auger furnace in the 500-800 °C temperature range for 3 h like in previous work experimental obtaining carbonized rice husk (cRH) [17].…”
