Role of Bio-Energy Plantations for Carbon-Dioxide Mitigation with Special Reference to India

Fuelwood plays an important role in the rural economy of the developing countries of Asia and Africa. Optimizing energy fixation in forest trees through high density energy plantations (HDEP), gasification of wood, and conversion of forest tree biomass, are some of the potential areas whereby additional research and development input for efficient management of atmospheric carbon in our energy system can be incorporated. For example, the photosynthetic efficiency of forest trees is rarely above 0.5%, which on the basis of theoretical considerations can be increased by up to 6.6%. Thus there is an ample scope to improve the efficiency up to 1%, which amounts to doubling of the productivity of the forests. Recent policy changes and experiences with wood-based bio-energy programmes in several countries indicate that woodfuels may become increasingly attractive as industrial energy sources. Use of biodiesel and the formulation of a project for undertaking 13.4 million ha of Jatropha plantations in India highlight the seriousness with which the Government of India is promoting carbon neutral energy plantations. The cost of establishment of plantations primarily for fuel production and its conversion to energy are major deterrents in this pursuit. Some of the issues in developing countries, like low productivity on marginal lands, degraded forest lands, and unorganized units for biomass energy conversion, result in cost escalation as compared to other energy sources. This paper revisits the scope for raising energy plantations, a comparison of the direct and indirect mitigation potential uses of plantations as an adaptation strategy through reforestation and afforestation projects for climate change mitigation and socio-economic issues to make this venture feasible in developing countries.     

四种填料充氧性能试验研究

在试验条件相同的情况下,对装有不同填料的四个反应柱进行了清水充氧性能试验及机理研究,试验采用氧总转移系数(KLa)、氧气转移率(dC/dt)、充氧能力(RO)、氧利用率(EA)、充氧动力效率(EP)五项指标进行充氧性能评价.研究认为填料能够显著提高曝气设备的充氧性能,与空白柱相比,浮石填料柱的5项评价指标均提高了31%,陶粒柱1、陶柱柱2和陶粒柱3则分别提高了7%、19%和17%,浮石填料柱的充氧性能明显优于其它填料柱.
