Hydrotreating of FCC decant oil as a needle coke feedstock.

Effects of Molecular Composition and Carbonization Reactivity of FCC Decant Oil and Its Derivatives on Mesophase Development

Introduction FCC decant oil is the primary feedstock to delayed coker to produce needle coke, a premium carbon precursor to synthetic graphite electrodes. Mesophase development during coking, determines the graphitizability of the needle coke product. Mesophase development, in turn, depends on the molecular composition of the feedstocks [1,2]. In a commercial delayed coking unit, liquid-phase c...

Regeneration of Hydrotreating and FCC Catalysts

2007: Graphite Electrode and Needle Coke Development

The booming Asian economies are driving the recent increase in steel production. Although BOF steel production growth is much stronger than EAF, the outlook for EAF is promising due to increasing substitution of steel scrap by DRI and pig iron, as well as an increase in electrical energy supply in China. The favorable operational reliability of AC-furnaces is the reason that most new furnace pr...

Waste Cooking Oil as an Alternate Feedstock for Biodiesel Production

As crude oil price reach a new high, the need for developing alternate fuels has become acute. Alternate fuels should be economically attractive in order to compete with currently used fossil fuels. In this work, biodiesel (ethyl ester) was prepared from waste cooking oil collected from a local restaurant in Halifax, Nova Scotia, Canada. Ethyl alcohol with sodium hydroxide as a catalyst was use...
