Description

"Rational Utilization and Development of Fuels" PPT courseware on fuels and their utilization (Lesson 2), 17 pages in total.

Introduction of new courses

How do you feel when you are walking on the road and a car passes you?

Why is there so much smog in winter?

New lesson explanation

1. The impact of fossil fuels on the environment

1. The harm of acid rain

(1) Destroy crops, forests and grasslands, and acidify soil;

(2) Entering rivers and lakes, seriously affecting the growth of fish in the water;

(3) Accelerate the corrosion of buildings, bridges, mechanical equipment, cultural relics, etc.

2. Impact of fuel combustion on the environment

3. Measures to reduce air pollution caused by vehicle exhaust

(1) Improve the engine to fully burn the fuel;

(2) Use catalytic purification devices to convert harmful gases into harmless substances;

(3) Use ethanol gasoline;

(4) Increase exhaust gas detection and prohibit cars that do not meet environmental standards from taking to the road.

2. Utilization and development of energy

1. Hydrogen

2. Preparation of hydrogen in laboratory

3. New energy

Summary

1. The burning of fossil fuels may have adverse effects on the environment. Fuels that do not pollute the environment or have little environmental pollution should be selected.

2. Fossil fuels are in danger of being exhausted. Clean fuels other than fossil fuels should be reasonably mined, used and developed. It is of great significance to comprehensively utilize resources and develop new energy sources.

Reinforcement exercises

1. Which of the following does not belong to new energy ()

A. Natural gas B. Tidal energy C. Biomass energy D. Wind energy

2. Protecting the earth and preventing environmental pollution are our important responsibilities. Rational use of resources is an important way to protect the earth. Among the following statements about resource utilization, the incorrect one is ()

A. Use solar energy to generate electricity B. Promote the use of electric vehicles

C. Advocate “low-carbon life” and green travel D. Centralized incineration of urban waste

3. German Audi Automobile Company announced that it has produced a vehicle fuel: "e-diesel" (e-diesel) using water and carbon dioxide as raw materials to alleviate the global energy crisis. Which of the following statements about this technology is incorrect ()

A. The combustion of "e-fuel" will no longer produce water and carbon dioxide. B. The use of "e-fuel" can prevent the occurrence of acid rain.

C. Water and carbon dioxide can produce different products under different conditions. D. Chemistry plays an important role in energy and environmental protection.

Homework

Energy is the basis for human survival and development.

(1) Give an example of the application of new energy in life and production.

(2) In order to save energy and avoid pollution, what are the conditions for full combustion of fuel? (Just answer one question)

(1) Solar energy is used for water heaters;

(2) There must be enough air during combustion (or the contact area between fuel and air must be large enough).
