  • 14534.生物燃料产业发展的投资部署影响

    [电力、热力、燃气及水生产和供应业] [2014-11-14]

    In support of the national goals for biofuel use in the United States, numerous technologies have been developed that convert biomass to biofuels. Some of these biomass to biofuel conversion technology pathways are operating at commercial scales, while others are in earlier stages of development. The advancement of a new pathway toward commercialization involves various types of progress, including yield improvements, process engineering, and financial performance. Actions of private investors and public programs can accelerate the demonstration and deployment of new conversion technology pathways. These investors (both private and public) will pursue a range of pilot, demonstration, and pioneer scale biorefinery investments; the most cost-effective set of investments for advancing the maturity of any given biomass to biofuel conversion technology pathway is unknown. In some cases, whether or not the pathway itself will ultimately be technically and financially successful is also unknown. This report presents results from the Biomass Scenario Model -- a system dynamics model of the biomass to biofuels system -- that estimate effects of investments in biorefineries at different maturity levels and operational scales. The report discusses challenges in estimating effects of such investments and explores the interaction between this deployment investment and a volumetric production incentive. Model results show that investments in demonstration and deployment have a substantial positive effect on the development of the biofuels industry.

    [电力、热力、燃气及水生产和供应业,专用设备制造业,电气机械和器材制造业] [2014-11-14]

    The upper operating temperature of tubes in heat exchangers/steam generators is strongly influenced by the degradation that can occur because of the reaction of the exchanger/generator tubing with the deposits that accumulate on the surface of the tubes. In fact, severe corrosion has been observed in some biomass fired systems, particularly with elevated potassium and chlorine concentrations in the deposits. Wood gasifiers have recently been and are currently being constructed at several sites in North America. In these systems, the syngas is burned to produce steam and the performance of the heat exchanger tubes under ash deposits is of great concern. As temperatures of the heat exchangers are increased in an effort to increase their operating efficiency, the performance of the tubes is of greater interest. The corrosion behavior of alloy steel tubes as a function of temperature has been investigated by exposing samples of selected alloys to ash collected from the steam generator fired by syngas produced in wood gasifiers. This study compares corrosion rates from laboratory exposures of synthesis gas and ash at 500 degrees C and 600 degrees C.

  • 14536.先进的可替代和可再生柴油燃料:物理和化学性质的详细描述

    [电力、热力、燃气及水生产和供应业,石油加工、炼焦和核燃料加工业] [2014-11-14]

    This report documents and compares the results of detailed analyses of the physical and chemical properties of ten advanced alternative and renewable diesel fuels and four commercial ultra low sulfur diesels (ULSDs). A key objective of this study conducted by the AVFL-19 Working Group of the Coordinating Research Council (CRC) Advanced Vehicle/Fuel/Lubricants Committee was to identify the similarities and differences of these emerging advanced alternative and renewable fuels compared to conventional petroleum derived ULSDs. The four advanced alternative fuels consisted of samples derived from gas-to-liquids (GTL), shale oils, and oil sands. The six renewable fuels were derived from biomass sources including plant, animal, and algal lipids and cellulosic materials. For all of these renewable fuels, none of the oxygen atoms inherent in the starting feedstock were detected, suggesting that they have been hydroprocessed. The four ULSDs were produced at different refineries in the US.

  • 14537.柳枝稷,宝贵的生物质能源作物

    [电力、热力、燃气及水生产和供应业] [2014-11-14]

    In this chapter, we review the physiology of switchgrass from seed dormancy till the effects of water and nutrie nts stress on grown plants. These characteristics are presented and discussed mainly at the canopy and whole-plan! level with emphasis on the agro-physiology of the speci es in view of the possible contribution of crop physiology to agricultural de velopment . Swilchgrass is noted for the variable degrees of seed donnancy regulated by endogenous and exogenous factors that determine the successful seedli ng estab lishment. Plant growth rates are determined by temperature while the reproductive phase is controlled mainly by pbotoperiod. There is also evidence that some physiological attlibutes, such as photosynlhesis, transpi ration, and waler use efficiency differ between letraploid, hexaploid, and octoploid ecotypes. But despite these ditTerences, in general switchgrass combines important attributes of efficient use of nu trients and water with high yields thanks to its ability to acqu ire resources from extended soil volumes, especially at deep layers. Moreover al canopy level , resou rcescapture and conservation are determined by morpho-physiological characteristics (C4 photosynthetic pathway, stomatal control of tran 'piration, high leaf area index, low light extinction coefficient) that enhance radiation use efficiency and reduce carbon losses. However, specific information on switchgrass physiology is still missing, in particular deeper understanding of physiological principles controlling the water and nutrients acquisition mechanisms and allocation under suboptimal growing conditions. The physiology of tillering and root respiration are also factors that need further investigation.

  • 14539.用于自身可持续发展分布式可再生能源生态系统的绿色星球架构方法论

    [电力、热力、燃气及水生产和供应业,信息传输、软件和信息技术服务业,水利、环境和公共设施管理业] [2014-11-14]

    This planet has been endowed with a host of natural mechanisms to keep the environment and climate in balance. Humans are now facing the need to restore this balance that has been upset in the past years because of a growing population and resource demands. To steer dependency away from freshwater crops and decrease environmental damage from humanity s fuel and energy demands, it is necessary to take advantage of the natural adaptive biomass resources that are already in place. Using methods of "Green Planet Architecture," based on compilations of current research and procedures, could lead to new forms of energy and fueling as well as new sources for food and feed. Green Planet Architecture involves climatic adaptive biomass; geospatial intelligence; agri- and aqua-culture life cycles; and soil, wetland, and shoreline restoration. Plants such as Salicornia, seashore mallow, castor, mangroves, and perhaps Moringa can be modified (naturally, model-assisted, or genetically) to thrive in salt water and brackish water or otherwise not arable conditions, making them potentially new crops that will not displace traditional farming. These fueling sources also have potential to be used in other rapid-growth industries, such as the aviation industry, that have incentive to move towards more sustainable fuel supplies. This report highlights an example of how synergistic development of biomass resources and geospatial intelligence high-performance computing capabilities can be focused to resolve potential drought-famine problems. These techniques provide a basis for future e-science-based discovery (and access) through technology that can be expanded to support global societal applications.
