The process by which atoms are rearranged into different molecular structure in the petroleum refining process is referred to as
catalytic cracking
hydrocracking
polymerization
reforming
Explication
Reforming is a chemical process that changes the molecular structure of hydrocarbons to improve their properties. It's often used to improve the combustion characteristics of low-quality gasoline stocks. Reforming can be done using thermal or catalytic methods.
