Other alternative energy sources
In the new pattern of energy consumption in China, the energy endowment pattern of China's rich coal and less oil determines coal-to-oil, and coal-based oil has a comparative cost advantage. Biomass oils are clean, environmentally friendly and renewable, and will become an important transportation energy source in the medium and long term. At present, alcohol ether fuel is a potential alternative energy source, especially dimethyl ether is the best choice to replace LPG. When the oil price is higher than 35 US dollars / barrel, coal liquefaction and coal alcohol ether fuel have a competitive advantage; the economic analysis of coal head and gas head alcohol ether fuel results in the production of alcohol ether per cubic meter of natural gas price The fuel cost corresponds to about 400 yuan/ton of coal price; the crude oil price falls by 40 dollars/barrel, and coal-to-olefins still have a competitive advantage. The demand for methanol as a fuel and raw material will increase substantially; while coal liquefaction is still cautious due to large investment and technical risks; methanol to olefins is a promising direction for coal chemical industry development due to its low cost.
