The potential of co-producing two different biofuels from a lignocellulosic substrate (wheat straw), according to a biorefinery concept, has been investigated. For such a purpose, simultaneous saccharification and fermentation (SSF) from the hemicellulosic and cellulosic fractions was performed for maximizing bioethanol production. The non-washed water-insoluble solid (WIS) fraction from the pretreated...
This article describes the reactive kinetics of Ca-based synthetic sorbent composed of 25wt.% mayenite (Ca12Al14O33) and CaO with CO2 at temperatures of 1023K for multiple cycles. The carbonation reaction is a gas–solid reaction system, which generally follows one out of two controlled regimes, namely the kinetic- and product layer diffusion (PLD) controlled regimes. A mathematical model based on...
In this work a series of carbon adsorbents were prepared from a low-cost biomass residue, olive stones. Two different approaches were studied: activation with CO 2 and heat treatment with gaseous ammonia. The results showed that both methods are suitable for the production of adsorbents with a high CO 2 adsorption capacity, and their potential application in VSA or TSA systems for...
