Petrochemistry is the branch of chemistry that focuses on the transformation of petroleum and natural gas into useful products. It involves the study of the chemical processes that convert raw materials from fossil fuels into a variety of chemicals, plastics, and fuels. This field plays a crucial role in producing everyday items, such as plastics, synthetic fibers, and fertilizers. The processes in petrochemistry typically include refining, cracking, and polymerization. These methods break down complex hydrocarbons found in crude oil into simpler compounds, which can then be reassembled into new materials. Petrochemistry is essential for the development of many products that support modern life and industry.
