Study on Co-gasification Characteristics of Biomass and Coal

The steam gasification characteristics of biomass char, coal char and the mixture of biomass char and coal char were studied in a thermobalance device. The steam gasification experiments of biomass char (rice stalk char, sorghum stalk char and corn stalk char), Shenmu coal char and the mixture of biomass char and coal char were carried out by temperature programmed thermogravimetry. The results show that the gasification rate of biomass char and coal char at a certain temperature is: sorghum char> rice stalk char> corn char> Shenmu coal char. The kinetic analysis of the steam gasification reaction of three kinds of biomass coke, coal coke, bio-coke and coal coke mixture is carried out, and the analysis shows that the continuous reaction model can reflect the steam gasification reaction dynamics of the coke sample to a certain extent.

China's New Energy 5 Trends Outlook, 8 Transformation Countermeasures

At present, the world's energy mainly depends on the burning of fossil fuels (coal, oil, natural gas). The higher the energy consumption, the more it will affect the sustainable development of human society. First, the burning of fossil fuels will bring a variety of environmental problems (especially climate change problems); second, because fossil fuels are not renewable, resources will eventually be exhausted. China is the world's largest energy consumer, but China's energy and mineral endowments are characterized by rich coal, lack of oil, and lack of gas. In 2021, China's dependence on foreign crude oil will reach 72%, and the dependence on natural gas will reach 46%. China's energy security issues are prominent.

Anhui: Encourage social capital investment, collective land equity development of rural renewable energy

The "Regulations" clarify the basic goals of rural energy development and utilization, that is, to promote the application of renewable energy such as biomass energy and solar energy according to local conditions, increase the resource utilization rate of agricultural and forestry wastes, and build a multi-energy complementary system for the integration of urban and rural areas in the county. People's governments at or above the county level are required to focus on supporting the development and utilization of rural energy in areas rich in solar energy, wind energy, geothermal energy, and micro-water resources, and organize the promotion of rural energy technologies such as photovoltaic power generation. The Regulations require that for the construction of rural energy projects, including solar photovoltaic power stations above the 1 kW level and below the 5 kW level and wind power stations above the 5 kW level and below the 10 kW level, the construction unit shall submit the design plan to the public power system of the rural energy department of the people's government at or above the county level. The "Regulations" encourage social capital to invest in rural energy development and utilization, and develop new models and new formats such as contract energy management and operation, and integrated energy services. Encourage the owners of rural collective construction land to cooperate with other market entities and individuals in the development and utilization of rural energy through land use rights, joint ventures, etc.
