Hydrocracking is a specific operation that takes a fraction of petroleum called gas oil which is heavy and cracks it into smaller molecules that are suitable for incorporation into gasoline, diesel, and jet, with an emphasis on the latter two.his occurs at high temperature with a very different set of catalysts than that used in either hydrotreating or hydrogenation processes. The hydrogen is used both as a mechanism to hydrogenate olefins and as a quench for temperature control.

Hybrid fiber-coaxial (HFC) is a telecommunications industry term for a broadband network that combines optical fiber and coaxial cable.It has been commonly employed globally by cable television operators since the early 1990s.s of 2015, the downstream signal is a RF modulated signal that typically begins at 50 MHz and ranges from 550â1000 MHz on the upper end. The fiber optic node also contains a reverse/return path transmitter that sends communication from the home back to the headend.
