What catalyst is used in hydrotreating?
However, metal oxides, that is, alumina-supported metal sulfides are, by far, the most utilized catalysts for hydrotreating. They possess a lower cost, higher resistance to impurities typically present in waste feedstock and allow co-hydroprocessing of plant lipids and petroleum feeds in existing refinery facilities.
What is catalytic hydrotreating?
Catalytic hydrotreating: A refining process for treating petroleum fractions from atmospheric or vacuum distillation units (e.g., naphthas, middle distillates, reformer feeds, residual fuel oil, and heavy gas oil) and other petroleum (e.g., cat cracked naphtha,coker naphtha, gas oil, etc.)
What is distillate hydrotreating?
The distillate hydrotreater is a category of hydrotreaters that treats distillate streams from atmospheric distillation and from conversion units to reduce their sulfur content and to improve their properties for blending into diesel.
What is the need of hydrotreating?
The purpose of a hydrotreater unit is primarily to remove sulfur and other contaminants from intermediate streams before blending into a finished refined product or before being fed into another refinery process unit.
What is the process of hydrotreating?
During hydrotreating, crude oil cuts are selectively reacted with hydrogen in the presence of a catalyst at relatively high temperatures and moderate pressures. The process converts undesirable aromatics, olefins, nitrogen, metals, and organosulfur compounds into stabilized products.
How is hydrotreating process?
How much does naphtha cost?
Is naphtha the same as kerosene?
Naphtha (/ˈnæpθə/ or /ˈnæfθə/) is a flammable liquid hydrocarbon mixture. Mixtures labelled naphtha have been produced from natural gas condensates, petroleum distillates, and the distillation of coal tar and peat. In different industries and regions naphtha may also be crude oil or refined products such as kerosene.
