I would like to know the composition of liquefied petroleum gas; in which book or standard can I find this information? For example, it can be found online that \"Liquefied petroleum gas is a by-product obtained by refineries during the catalytic cracking and thermal cracking of crude oil.\" The main components of catalytic cracking gas are as follows (%): hydrogen 5–6, methane 10, ethane 3–5, ethylene 3, propane 16–20, propylene 6–11, butane 42–46, butenes 5–6, and hydrocarbons with 5 or more carbon atoms 5–12. The main components of the pyrolysis gas are as follows (%): hydrogen 12%, methane 5–7%, ethane 5–7%, ethylene 16–18%, propane 0.5%, propylene 7–8%, butane 0.2%, butylene 4–5%, and hydrocarbons with 5 or more carbon atoms 2–3%. ”I want to know where this information comes from.
Looking at your content, it seems to be material related to refining. Unless you work in the LPG deep processing industry, such detailed information is generally not necessary.
