Hydrofining - an overview | ScienceDirect Topics
网页Hydrofining is a process used for reducing the sulfur content of feedstocks by treating the feedstock in the presence of a catalyst. This process can be applied to lubricating oil, naphtha, and gas oil.
Hydroprocessing - an overview | ScienceDirect Topics
网页Hydroprocessing is a catalytic process that enables targeted catalytic reactions with the addition of hydrogen. The aim of hydroprocessing is to increase the hydrogen-to-carbon ratio and to almost completely remove undesirable heteroatoms such as sulfur, nitrogen, oxygen and some metals.
Kinetic Model for Low-Temperature Coal Tar Hydrorefining
网页In this work, the hydrorefining of coal tar was carried out in a three-stage fixed-bed reactor to produce clear fuel. Three catalysts containing hydroprotecting (HP) catalyst, hydrodesulfurization (HDS) catalyst, and hydrodenitrification (HDN) catalyst were loaded into three reactors in sequence in the grading ratio of 0.23:0.3:0.47. Based on ...
Hydrotreating in Petroleum Processing | SpringerLink
网页2014年12月30日 · Hydrotreating or catalytic hydrogen treating removes objectionable materials from petroleum fractions by selectively reacting these materials with hydrogen in a reactor at relatively high temperatures at moderate pressures. These objectionable materials include, but are not solely limited to, sulfur, nitrogen, olefins, and aromatics.
Production of jet fuel by hydrorefining of Fischer-Tropsch wax …
网页2021年9月15日 · The most effective strategy to produce jet fuel via the F-T route is the production of paraffin wax (long-chain hydrocarbons) followed by hydrorefining. The jet fuel produced through hydrorefining of F-T waxes mimics the chemistry of petroleum jet fuel.
Modern Approaches to Hydrotreating Catalysis | SpringerLink
网页The preparation, activation, composition and structure of catalysts are discussed, along with the associated causes of catalyst deactivation and ultimate catalyst lifetime in each process. The approaches to new and improved catalytic processes and the production of more-active catalysts are also discussed.
Integrated tuneable synthesis of liquid fuels via Fischer–Tropsch ...
网页2018年9月17日 · Here, we report an integrated catalytic process for the direct conversion of syngas (CO/H 2) into different types of liquid fuels without subsequent hydrorefining post-treatments of Fischer ...
US4243519A - Hydrorefining process - Google Patents
网页Hydrorefining is a well known process for upgrading a variety of hydrocarbon fractions. Naphtha fractions are subjected to hydrorefining by treating with hydrogen and a hydrorefining...
Hydroprocessing of Coal Tar to Prepare Clean Fuel Oil
网页Catalytic hydrorefining of tar to liquid fuel over multi-metals (W-Mo-Ni) catalysts. In the perspective of fossil fuel depletion, the importance of renewable and substitute fuels is remarkable. In this study, clean liquid-fuel was obtained from …
