There is provided a process for upgrading a hydrocarbon material. The process includes: (a) treating a hydrocarbon material-comprising feed, wherein the treating includes cracking a hydrocarbon material-comprising feed, such that an upgraded intermediate is produced; and (b) in the absence, or the substantial absence, of adscititious diatomic hydrogen, reducing the content of olefinic material within at least a fraction of the upgraded intermediate such that an olefinic material content-reduced product is produced.
