Title:  Research On 'Electricity-Carbon-Ecology' Collaborative Planning Technology In Desert And Gobi Area

Abstract: Vigorously developing the wind and solar resources in desert and Gobi areas has become an important part of the future development of new energy in China. However, the ecological environment in the desert and Gobi areas is fragile, the local load is small, the conventional water /fire power supply configuration is difficult, and the power grid conditions are weak. How to orderly and scientifically develop the large-scale new energy contained in the desert and Gobi area, promote the restoration of the ecological environment, and promote the development of regional industries has become a new challenge. In response to this problem, this report first analyzes the challenges faced by new energy in the system planning, operation control and development model in the desert and Gobi area from the perspective of building an intelligent energy and ecology system. Secondly, aiming at the planning and construction of large-scale new energy base in desert and Gobi area, the collaborative optimization planning technology of the three is expounded from the perspective of ‘power-carbon-ecology’ coupling. Finally, the opportunities and challenges brought by the development of new energy in the desert and Gobi area are summarized and prospected.

Title: Development on Biomass combustion and gasification technologies based on fluidized bed process

Abstract: Biomass is one of main renewable energy resource, meanwhile, the environment pollution due to burning or piling up the agriculture waste in land is serious. To using the agriculture/forest waste in clean and high efficiency, biomass gasification technologies have been developed based on fluidized bed process in Zhejiang University. Based on the research on the mechanism of biomass combustion, the transform process of  alkali/chlorine (KCl) and high temperature corrosion due to alkali and chlorine, biomass circulating fluidized bed gasification technology is developed for agriculture waste. The first circulating fluidized bed gasifier (8t/h) fired with rice husk/corn stalk (50%:50%) coupled with large scale coal pulverized coal plant in China is operated successfully in July, 2018. To increasing the unitization benefit of the biomass, a new biomass fluidized bed gasification technology cogenerated char and steam is developed and operated successfully.

Title: Research on sewage sludge hydrothermal liquefaction and its products utilization

Abstract: Hydrothermal liquefaction (HTL) is an effective thermochemical process for sewage sludge treatment. Its main product is biocrude (a crude bio-oil), along with some by-products including aqueous phase, gases and solids. HTL can effectively achieve the purposes of reduction, stabilization, harmless and resource recovery for sewage sludge treatment. Many efforts are continued extensively to improve conversion efficiency and process economy so as to promote the industrial application of this technology. This work systematically investigates critical influencing factors (e.g., reaction temperature, residence time, solvent, catalyst, and pretreatment) and fundamental transformation mechanisms of main components (i.e., lipids, proteins, and carbohydrates) during sewage sludge HTL. Moreover, the application of HTL products is comprehensively studied. Reusing the aqueous phase and solid products as reaction medium and catalyst carrier respectively after sewage sludge HTL seems to be feasible to realize resource utilization of sewage sludge. Potential challenges and opportunities are also highlighted in this work. It is necessary to develop advanced methods for catalyst recovery and innovative biocrude upgrading methods so as to reduce investment and operating costs. This information can provide valuable guidance to promote the industrialization of sewage sludge HTL.

Title:The working fluid improvement and optimization for organic Rankine cycle

Abstract: The utilization of renewable energy and waste heat recovery can effectively alleviate the ongoing energy crisis and environmental pollution. The organic Rankine cycle has been proven to be reliable in converting low-to-medium-grade thermal energy to power. The organic refrigerant is a crucial factor in the organic Rankine cycle design procedure, because the cycle performance depends mainly on the thermophysical properties of the working fluid. In this report, the speaker will present some related works they are currently working on.
