https://www.osha.gov/dts/osta/otm/otm_iv/otm_iv_2.html - This website is from the Occupational Safety and Health Administration in the United States Departments of Labor and is an excellent source for all the stages of the refining process, including desalting, atmospheric distillation, vacuum distillation, solvent extraction and dewaxing, thermal cracking, catalytic cracking, hydrocracking, catalytic reforming, catalytic hydrotreating, isomerization, polymerization, and the list goes on. This is extremely detailed, but very well thought out in its organization and explanation. It is more information than students need to know; however, the information can be manipulated easily for assigned student reading. It is written so that high-schoolers can understand it and "Table IV:2-3. Overview of Petroleum Refining Processes" gives information about what the end products at each stage are used for.
http://www.world-petroleum.org/index.php?/Technology/petroleum-refining-courtesy-of-aip.html - This website is not nearly as detailed as the one from OSHA. Its big advantage for chemistry teachers is that it gives some of the chemical processes in chemical equation form; therefore, students can use those equations to practice balancing equations, mole-mass convertions, mole-mole ratio, etc.

The five preceeding websites can be used independently but they are also linked together. These are clearly written and very succinct. Some have videos, links to videos and links to other pages, such as "What's the difference between gasoline, kerosene, diesel, etc.?"
