“…Amarasekara and Owereh (2010) used solid acid, which was prepared by strong acid (-SO3H) ionic liquid and SiO2 to catalyze the hydrolysis of cellulose in the [BMIM]Cl system, leading to a sugar yield of 67% (Amarasekara and Owereh 2010). However, the physical properties of biomass-based solid acid are similar to those of the hydrolytic residue of biomass, which gives rise to difficulties in the separation and recycling of the solid acid (White et al 2009). A solid acid catalyst with magnetic characteristics has advantages in separation and recycling and has shown catalytic activity equal to that of a conventional solid acid catalyst (Berry and Curtis 2003).…”

Solid acid catalysts show good catalytic depolymerization behavior for lignocellulose. A stable core-shell structured magnetic solid acid catalyst (MSAC), Fe3O4/C-SO3H, was prepared from glucose, concentrated sulfuric acid, and modified magnetic particles of Fe3O4, which was used as the core. The effects of the carbonization and sulfonation processes on the activity of the catalyst were investigated. The results showed that preparation conditions had great influence on the quantity of the acidic groups (sulfonic, carboxyl, and hydroxyl groups) and the stability of magnetic catalysts. The best preparation conditions for MSAC were 3 h of carbonization time, 450 °C as the carbonization temperature, 9 h of sulfonation time, and 90 °C as the sulfonation temperature. Its surface topography, functional group, chemical composition, and magnetic properties were characterized by analysis instrument. Furthermore, the catalyst was stably dispersed in the reaction system, quickly separated from the reaction system using an external field, and reused many times; 44.3% of xylose yield was obtained at 160 °C for 16 h. The catalyst was used repeatedly more than 3 times, and the recovery over 89%. The depolymerization of corncobs was achieved by magnetic catalyst, representing the depolymerization characteristics of real lignocellulose. This data can be used as a reference for the subsequent use of biomass resource.

“…Biomass represents a cost-effective and widely available option for the preparation of carbon materials (Mohan and Pittman, 2006;White et al, 2009;Kalyani and Anitha, 2013). For example, CO 2 could be substantially adsorbed on olive stone or almond shell (both are low-cost biomass residuals) derived carbon materials (Plaza et al, 2009).…”

Solid Adsorbents for Low-Temperature CO2 Capture with Low-Energy Penalties Leading to More Effective Integrated Solutions for Power Generation and Industrial Processes

CO 2 capture represents the key technology for CO 2 reduction within the framework of CO 2 capture, utilization, and storage (CCUS). In fact, the implementation of CO 2 capture extends far beyond CCUS since it will link the CO 2 emission and recycling sectors, and when renewables are used to provide necessary energy input, CO 2 capture would enable a profitable zero-or even negative-emitting and integrated energy-chemical solution. To this end, highly efficient CO 2 capture technologies are needed, and adsorption using solid adsorbents has the potential to be one of the ideal options. Currently, the greatest challenge in this area is the development of adsorbents with high performance that balances a range of optimization-needed factors, those including costs, efficiency, and engineering feasibility. In this review, recent advances on the development of carbon-based and immobilized organic amines-based CO 2 adsorbents are summarized, the selection of these particular categories of materials is because they are among the most developed low-temperature (<100°C) CO 2 adsorbents up to date, which showed important potential for practical deployment at pilot-scale in the near future. Preparation protocols, adsorption behaviors as well as pros and cons of each type of the adsorbents are presented, it was concluded that encouraging results have been achieved already, however, the development of more effective adsorbents for CO 2 capture remains challenging and further innovations in the design and synthesis of adsorbents are needed.Keywords: CCUS, CO 2 capture, adsorption, energy, material science INTRODUCTION CO 2 CAPTURE AND AN INTEGRATED ENERGY-CHEMICAL SOLUTIONThe atmospheric CO 2 concentration now exceeds 400 ppm (CO2Now.org, 2014), and its continuous increase is believed to be the major factor leading to global warming and climatic change (Crowley, 2000;Held and Soden, 2000;Patz et al., 2005). Kaya et al. and Hoffert et al. have quantified net CO 2 emissions in terms of population, economic activity, and energy-related factors using Eq. 1 (Kaya, 1995;Hoffert et al., 1998).where C is the net CO 2 emission, P is population, GDP is the gross domestic product that is used here as an indicator of economyrelated factor, and E is energy production. Therefore, GDP/P is the Per capita GDP, and E/GDP can be regarded as the energy intensity during production that is closely related to the efficiency of energy utilization. The last term, C/E, represents the carbon intensity during energy production. As for the development of the human society and life quality, it is improper to limit population and production, which means there is no solution to CO 2 reduction from the first and second term in Eq. 1. On the other hand, increase in the energy production/utilization efficiency and control of the carbon footprint during energy processes are the major strategies for CO 2 sequestration (third and fourth term in Eq. 1). The complete decarbonization of energy is believed to be the ultimate solution for the long-term sustainability, ...
