“…A carbon cycle for the production of synthetic fuels from biomass and carbon-resources can be seen in Fig. [150][151][152][153][154][155] It was reported that the addition of 10% Scots pine to the coal conversion process can result in a significant 3% reduction in non-renewable carbon emissions and even zero fossil CO 2 emission. Biomass can be directly or indirectly converted into bio-oils, fuels, high value chemicals, food etc.…”

This review summarizes how the carbon cycle occurs and how to reduce CO2 emissions in highly efficient carbon utilization from the most abundant carbon source, coal. Nowadays, more and more attention has been paid to CO2 emissions and its myriad of sources. Much research has been undertaken on fossil energy and renewable energy and current existing problems, challenges and opportunities in controlling and reducing CO2 emission with technologies of CO2 capture, utilization, and storage. The coal chemical industry is a crucial area in the (CO2 value chain) Carbon Cycle. The realization of clean and effective conversion of coal resources, improving the utilization and efficiency of resources, whilst reducing CO2 emissions is a key area for further development and investigation by the coal chemical industry. Under a weak carbon mitigation policy, the value and price of products from coal conversion are suggested in the carbon cycle.

“…A set of recent data for three experimental systems was chosen for model validation since they present detailed information regarding feedstock and product composition under typical operating conditions, and distinct gasifier configurations. More specifically, these systems involve coalbiomass co-gasification in entrained-flow (Hernández et al, 2010) and fluidized-bed gasifiers (Li et al, 2010;Song et al, 2013) in the temperature ranges of 1000 to 1150 ºC, at atmospheric pressure, and using air/steam as gasifying agent.

“…The co-processing of coal-biomass blends can be carried out such that undesirable characteristics of one fuel can be compensated by desirable ones brought by the other. Some authors (Sjöström et al, 1999;Hernández et al, 2010;Xu et al, 2011;Song et al, 2013) have observed synergies using some combinations of these fuels. However, other authors (Collot et al, 1999;Zhu et al, 2008) reported the lack of interactions among fuels.…”

-Coal and biomass are energy sources with great potential for use in Brazil. Coal-biomass cogasification enables the combination of the positive characteristics of each fuel, besides leading to a cleaner use of coal. The present study evaluates the potential of co-gasification of binary coal-biomass blends using sources widely available in Brazil. This analysis employs computational simulations using a reliable thermodynamic equilibrium model. Favorable operational conditions at high temperatures are determined in order to obtain gaseous products suitable for energy cogeneration and chemical synthesis. This study shows that blends with biomass ratios of 5% and equivalence ratios ≤ 0.3 lead to high cold gas efficiencies. Suitable gaseous products for chemical synthesis were identified at biomass ratios ≤ 35% and moisture contents ≥ 40%. Formation of undesirable nitrogen and sulfur compounds was also analyzed.

“…Gasification enables an attractive route for converting carbonaceous fuels cleanly and high-efficiently into fuel gas, synthesis gas, and other valuable energy products [1,2]. The most extensively used gasification agents include oxygen, air, steam, carbon dioxide, and any mixture of these agents.…”
