(under subclass 106) Processes wherein the cracking takes place in the presence of added hydrogen.
(1) Note. Hydrogenative cracking is generally referred to as destructive hydrogenation.
(2) Note. The hydrogen may be added as a free gas or a hydrogen rich material may be used under such conditions as to generate or liberate hydrogen (hydrogan donor processes).
