The US Department of Energy recently announced that it will allocate $385 million to fund six projects related to ethanol fuel development to promote the production of ethanol fuel from non-traditional energy sources such as wood chips, switchgrass and citrus peel. Three of these projects are used in the coal industry. Gasification technology process. Energy experts explained that the move shows that the US government attaches importance to the application of gasification technology in the field of renewable energy.
Many scientists believe that gasification technology will provide a more efficient, economical and environmentally friendly process compared to current ethanol fuel fermentation processes, and is suitable for a variety of renewable energy fuel production. On the one hand, the gasification technology helps to reduce the cost of the fermentation process and solves the problem that the biological raw materials are not easy to release the starch in the fermentation process. Currently, a relatively expensive reactor is needed in the fermentation process to solve this problem. On the other hand, syngas directly produced by the gasification process can be easily converted into other fuels, chemicals and materials. In addition, the long-term application of gasification technology in the coal industry shows that it is also an environmentally friendly technology.
What makes the US Department of Energy more interested is that gasification technology can solve the problem that the United States is too dependent on corn to produce ethanol fuel, and expand the sources of biofuels other than corn. In view of the US President George W. Bush’s goal of renewable energy fuels, the United States is currently working on a plant that produces ethanol fuel from corn. The US Department of Agriculture reports that half of US corn production in 2007 will be used to produce ethanol. This has caused a red alert about corn food security.
US Department of Energy officials said that the application of gasification technology in the field of renewable energy has shown good feasibility. In 2001, a US-based plant that produces wood fuel from wood chips has the capacity to produce 200 megawatts of electricity per day. However, in order to promote the competitiveness of the gasification process, it is necessary to increase the optimization study of the catalyst to better reduce the production cost of the process.
