World Oil Network News: As is well known, trees that were buried underground hundreds of millions of years ago can, under the effects of prolonged sealing and high pressure, turn into an important fossil fuel – coal. Today, scientists are turning their attention to the trees that are thriving on the Earth’s surface: since nature can use ancient trees to provide fuel for humans, humans should also be able to use modern trees to produce biodiesel—also known as bio-liquid fuel. In fact, from ancient times to the present, firewood has been an essential and important source of energy for humanity. It can be traced back to early humans drilling wood to make fire, using kindling as fuel ； As far back as the first Industrial Age, humans used large pieces of wood as fuel to power ships and trains ； Even today, many people still use firewood for heating and cooking. It can be said that, whether in the past, at present, or even in the distant future, wood-based energy will always remain alongside humanity. However, this simple approach of just burning it away is neither economical nor hygienic, let alone environmentally friendly. Burning firewood not only fills the home with smoke but also produces a large amount of greenhouse gases. Therefore, the use of firewood also needs to consider sustainable development. For the sake of the Earth and humanity itself, the development and application of wood-based energy are also evolving with the times. For example, using the scraps from discarded firewood to produce biogas or ethanol ； Solid wood particles are used to produce wooden gaseous fuel, and even wooden liquid fuel. In areas rich in timber resources, converting solid wood into wooden gas or biomass liquefied fuel can serve as an excellent clean alternative energy source to replace natural gas, ethanol, propane, as well as oil and coal. In addition to improving the combustion and utilization efficiency of firewood, it can also reduce the greenhouse gases produced during combustion. Furthermore, converting solid wood fuel into clean combustible gases or liquids can also **simplify the transportation and storage of firewood. Scientists at Georgia State University in the United States have recently announced that they have developed a new process that allows for the creation of a new type of biofuel derived from wood particles; this biofuel has not yet been given an official name, and a patent application is currently in progress. It differs from previous liquid fuels derived from wood pellets; it can be mixed with biodiesel or gasoline to power conventional engines. In fact, scientists have long been able to produce oil from wood, but due to low production efficiency and high costs, it has not been feasible for practical use. This new chemical process developed by researchers at the University of Georgia enables the low-cost production and processing of this novel biofuel, allowing it to be used directly in gasoline engines, biodiesel engines, and conventional diesel engines. The principle of the new manufacturing process is as follows: Wooden particles with a diameter of about 1/4 inch and a length of around 6/10 inch are heated and decomposed in an environment of high temperature and low oxygen levels. One-third of these wooden particles turn into charcoal, while the remainder turns into gas, which is then condensed into a liquid for chemical treatment. Ultimately, about 34% of the biomass liquefied fuel (approximately 15%–17% of the net weight of the wood pellets) can be used to power engines. Researchers are currently working to improve this process in order to further increase the oil yield from wood pellets. Adams, the head of the research team, said that the new process is simple and easy to implement, and it holds promise for reducing the costs associated with producing large quantities of biomass liquefied fuel from wood. He hopes that this technology will benefit his hometown, as Georgia has 24 million acres of forests; the new technology can be used to harvest trees on a continuous basis to produce biomass liquid fuel, which will help address employment issues in the state, increase state revenues, and also reduce oil consumption and carbon dioxide emissions. Not only that, but the environmental benefits brought about by the new processing technologies are very significant. Researchers have set up test sites in Georgia to conduct small-scale experiments, aiming to determine whether the byproduct of producing this biofuel – large quantities of charcoal particles – can be used as fertilizer. If this approach is indeed economically viable, such biofuels will not only help achieve the goal of \"carbon neutrality,\" but they can even do better by achieving a negative carbon balance – not only will they not increase greenhouse gas emissions, but they will also reduce them. Adams explained that when you plant a tree, you are helping the Earth remove carbon dioxide from the atmosphere ； If, when using energy, you return some of the resulting carbon dioxide to the soil in an inert form, you are essentially reducing the amount of carbon dioxide in the atmosphere. The research team is extremely optimistic about their technology, as granular charcoal is very beneficial for most soils; it can **improve the ecological condition of the soil, help it retain moisture, and keep it fertile. Although this new type of liquid biofuel performs well at present, researchers still need to conduct further tests to assess its long-term impact on the power output, fuel efficiency, and emission characteristics of engines. They also need to study its combustion properties as well as the best methods for transporting and storing it, in order to accelerate the widespread use of this new liquid biofuel as soon as possible.
