They are Standardization Administration of China, National Development andReform Commission, Ministry of Land and Resources, Ministry of Establishment, Ministry ofCommunications, Ministry of Information Industry, Ministry of Waster Resources, Ministry ofAgriculture, Ministry of Commerce, General Administration of Quality Supervision, Inspection andQuarantine of the PRC, State Environmental Protection Administration, State Forestry Bureau, StateOceanic Administration and China Meteorological Bureau.

Parameter selection for the hydroconversion of waste polyethylene plastic under mild conditions: A comprehensive evaluation

The hydrogenolysis/hydrocracking of waste polyethylene(PE) has recently been intensively studied, with the general pursuit of low-temperature reaction conditions, increased oil-phase yield, and narrower carbon chain distribution. Before this, we utilized a ball-milled ZSM-22 catalyst loaded with Ru nanoparticles(NPs), which exhibited excellent hydroconversion performance. It deconstructed PE into >80 wt.% oil products under low temperatures and short reaction times. Herein, we investigated the influence of varying temperature/pressure parameters on the degree of specific hydrocracking/internal hydrogenolysis/terminal hydrogenolysis reactions. From the comprehensive energy efficiency perspective, including stirring, reaction, and product separation, as well as taking into account the degree of product isomerization and catalyst lifespan, we analyzed the optimization of parameters. This research abandons the notion that lower temperatures are better and proposes a more comprehensive evaluation framework for low-consumption hydroconversion of PE to produce high-value products.

Energy internet or comprehensive energy network?

What needs to be developed from the concept of"Smart Grid"is that:when renewable energy sources are absolutely prevailing in power generation,distributed power generation and distributed energy storage systems are widespread across the grid,and electric vehicle charging loads are prevailing in power load demands,how can the power grid support electric power as a core secondary energy source,undertake the role of a bridge between primary energy and end-use energy,and achieve the coordination and the optimization in macro energy perspective;how to guarantee the security of both macro energy and environment as well as the reliability of electricity.If a new term is needed,it should be Comprehensive Energy Network,not Energy Internet.

Xinjiang Energy-Based Desert Management Project

Xinjiang is an important area connecting China with other Central Asian countries and a strategic location for safeguarding national security.Its economic development is the core and key of China’s“the Belt and Road Initiative”strategy.However,there are existing problems in Xinjiang,such as water resource shortages,agricultural inefficiency,increasing desertification,and an imbalance in regional economic development.In response to these problems,the project team innovatively proposed a strategic concept of using energy to develop modem agriculture facilities in Xinjiang to control desertification.The Xinjiang Energy-Based Desert Management Project is guided by the concept of ecological civilization,and the promotion of Xinjiang’s desert governance system and modernization of governance capacity.
