What kind of oil can be used as a substitute for gasoline?
1 Answers
The following fuels can be used as substitutes for gasoline: 1. Natural gas: As early as the 1860s, the French used engines fueled by coal gas. Natural gas has a high octane number, causes less air pollution, and ensures good engine startup in winter. By 1980, there were already 400,000 vehicles worldwide converted to use natural gas as a power fuel. However, using natural gas requires vehicle modifications, and the equipment at natural gas refueling stations is larger and more expensive than that at regular gas stations. 2. Hydrogen: Liquid hydrogen is an effective fuel. Experimental cars using hydrogen as fuel have already been developed. The drawbacks of liquid hydrogen are its low density and extremely low boiling point. 3. Alcohol: Many scientists believe that methanol and ethanol in alcohol are the most realistic competitors to gasoline. The challenge lies in the limited availability of raw materials for alcohol production. Japan is researching the use of seaweed as a raw material, Norway is studying the extraction of alcohol from coniferous wood, Mexico has successfully extracted alcohol from cacti, and New Zealand has achieved initial success in using orange peels to produce automotive fuel. It is estimated that 1 square meter of plants can produce 1 kilogram of fuel.
