“…According to Cuiping et al (2004), biomass accounts for 14 percent of the world's energy consumption and is used as a primary energy source by more than half the world's population. Biomass fuels are unique with respect to fossil fuels because they are gathered from a large area and transported to a concentrated area for use whereas fossil fuels are produced from a single location (i.e., a coal mine) and dispersed over a large area for use.…”

“…Biomass fuels with moisture contents less than 10 percent are better suited for thermal energy conversion, while biomass with higher moisture contents produce better results from biochemical processes such as fermentation (Cuiping et al 2004). Since biomass fuels have lower concentrations of nitrogen and sulfur, oxides produced during the combustion process are significantly less than emissions produced by fossil fuels (Cuiping et al 2004).…”

“…From Table 3-10 it can be seen that compared to coal, soybeans contain higher proportions of hydrogen and oxygen. Cuiping et al (2004) reported that the higher proportions of hydrogen and oxygen decrease the heating value of a fuel due to carbon -hydrogen and carbon -oxygen bonds containing less energy than carboncarbon bonds. The significantly lower nitrogen and sulfur content of soybeans when compared to coal is also important for environmental protection.…”

The production of cement involves a combination of numerous raw materials, strictly monitored system processes, and temperatures on the order of 1500 °C. Immense quantities of fuel are required for the production of cement. Traditionally, energy from fossil fuels was solely relied upon for the production of cement. The overarching project objective is to evaluate the use of alternative fuels to lessen the dependence on non-renewable resources to produce portland cement. The key objective of using alternative fuels is to continue to produce high-quality cement while decreasing the use of non-renewable fuels and minimizing the impact on the environment.Burn characteristics and thermodynamic parameters were evaluated with a laboratory burn simulator under conditions that mimic those in the preheater where the fuels are brought into a cement plant. A drop-tube furnace and visualization method were developed that show potential for evaluating time-and space-resolved temperature distributions for fuel solid particles and liquid droplets undergoing combustion in various combustion atmospheres. Downdraft gasification has been explored as a means to extract chemical energy from poultry litter while limiting the throughput of potentially deleterious components with regards to use in firing a cement kiln. Results have shown that the clinkering is temperature independent, at least within the controllable temperature range. Limestone also had only a slight effect on the fusion when used to coat the pellets. However, limestone addition did display some promise in regards to chlorine capture, as ash analyses showed chlorine concentrations of more than four times greater in the limestone infused ash as compared to raw poultry litter.A reliable and convenient sampling procedure was developed to estimate the combustion quality of broiler litter that is the best compromise between convenience and reliability by means of statistical analysis.Multi-day trial burns were conducted at a full-scale cement plant with alternative fuels to examine their compatibility with the cement production process. Construction and demolition waste, woodchips, and soybean seeds were used as alternative fuels at a full-scale cement production facility. These fuels were co-fired with coal and waste plastics. The alternative fuels used in this trial accounted for 5 to 16 % of the total energy consumed during these burns. The overall performance of the portland cement produced during the various trial burns performed for practical purposes very similar to the cement produced during the control burn. The cement plant was successful in implementing alternative fuels to produce a consistent, high-quality product that increased cement performance while reducing the environmental footprint of the plant. The utilization of construction and demolition waste, woodchips and soybean seeds proved to be viable replacements for traditional fuels. The future use of these fuels depends on local availability, associated costs, and compatibility with a facility's p...

The synergistic interaction of rice husk (RH), Huaibei bituminous coal (HB coal), and their blends was investigated under O 2 /CO 2 combustion condition by thermogravimetric analysis. The RH was blended with HB coal in the range of 20-40 wt% to investigate the co-combustion profile. Meanwhile, a horizontal tube furnace was used to study the sulfur release characteristics of blended fuels under O 2 /CO 2 atmosphere. Results showed that the synergistic interaction between RH and HB coal improved the char catalytic effect and alkali metals melt-induced effect on the decomposition of HB coal. Burnout temperature (T b ) of blended fuels decreases significantly with an increase of RH ratio and oxygen ratio, ignition temperature (T i ) decreases with increases of RH ratio, while there is a minor decrease in T i at higher oxygen ratio. Combustion characteristic indexes of blended fuel increase with an increase of RH ratio and oxygen ratio. The SO 2 peak values decrease with increases of RH ratio, and increase with an increase of oxygen ratio and temperature. However, the mean SO 2 emissions and fuel-S conversions show the inverse trend.

This study presents the design and assessment of site‐specific supply chains and related manufacturing processes for the production of bio‐based chemicals from the syngas platform and via gasification of lignocellulosic biomass followed by syngas fermentation. The supply chains include feedstocks production and collection, biomass gasification, syngas fermentation, and downstream processing. For each of these stages, different alternatives were considered: four feedstocks (pine, corn stover, sugarcane bagasse, and eucalyptus), three products (ethanol, 2,3‐butanediol and hexanoic acid), and three geographical locations (the Netherlands, the USA, and Brazil). Conceptual development and analysis of the supply chains were done through the combination of different design and assessment tools, namely biomass supply chains design, fermentation process design (based on thermodynamics and transport), process simulation, and economic and environmental assessments. The minimum selling price (MSP) and two environmental impact categories, i.e., global warming potential (GWP) and non‐renewable energy use (NREU), were used as performance indicators. These were compared to data reported in scientific literature and commercial sources for similar processes and products. The best overall performance was obtained for the production of 2,3‐butanediol from pine sourced in the USA. In the cases of ethanol and hexanoic acid, the syngas fermentation stage had significant contributions to MSP, GWP, and NREU, due mainly to its high energy requirements. Regarding the geographical location, the best economic performance was obtained for the USA followed by the Netherlands and Brazil respectively. Furthermore, operation in Brazil led to the lowest environmental impacts, followed by the Netherlands and the USA. © 2017 Society of Chemical Industry and John Wiley & Sons, Ltd
