Classification by Natural Source
Petroleum-based alkane feedstocks
This is the primary industrial source of alkane feedstocks. Alkane fractions of varying carbon chain lengths-spanning products from gaseous to solid states-are obtained through the fractional distillation of crude oil. It is currently the most widely used type of alkane feedstock in the chemical industry.
Natural gas-based alkane feedstocks
Natural gas consists primarily of methane, accompanied by small amounts of low-carbon alkanes such as ethane and propane. Obtained through direct extraction, it serves as a key source of low-carbon alkanes and is commonly used as both a clean fuel and a basic chemical feedstock.
Bio-based alkane feedstocks
These are derived from microbial metabolism or synthesized within animals and plants-such as methane produced by methanogens or long-chain alkanes synthesized by certain organisms. Representing a renewable source of alkanes, they are currently utilized primarily in applications such as biogas production.
