Process modeling and kinetic estimation for desulfurization of diesel fuel using nano - ZnO/Al2O3 [PDF]
Chemical Industry and Chemical Engineering QuarterlyIn the present paper, a gamma alumina (γ-Al2O3) loaded zinc oxide (ZnO) nano-catalyst (ZnO/γ-Al2O3) has been synthesized and used to accelerate the removal of sulfur compounds from light gas oil by oxidative desulfurization (ODS) process. The synthesized

Advanced Functional Materials, EarlyView.A new class of sulfur‐free, oxygen‐bridged dibenzofuran‐based polymers is developed for ultrahigh‐refractive‐index applications. The rigid π‐extended architecture and enhanced molecular polarizability enable exceptional optical performance, combining refractive indices up to 1.848 with high Abbe numbers and full visible transparency. This work offers a

Present Status of Petroleum Refining Industry
Journal of the Fuel Society of Japan, 1955 石油精製工業は戦後消費地精製主義によつて急速に発展し西欧各国, 米国東海岸に大製油所が建設され, わが国では製油能力は消費量を凌駕している。新製油法としては流動接触分解法および接触改質法が目立ち, 高オクタン価ガンリンの生産に不可欠のものとなつている。プラットフォーミングなどで副生する水素は中東軽油のごとく硫黄分の高いものを水素処理するのに有利で西欧では既に実施されている。諸外国では重油の消費割合が少いので, FCC法, Vis breaking法, Delayed coking法, Fluid coking法などで重油の軽質化を行つている。肩本の場合では処理原油の大部分は直溜ガソリンのオクタン価の低い中東原油であるから, 將来オクタン価競爭などで, 80オクタン以上を標準にするとなれば ...

Mono‐Material Polydisulfides for Pressure Sensitive Adhesive Tapes With Closed‐Loop Recyclability
Advanced Functional Materials, EarlyView.A high‐performance pressure‐sensitive adhesive (PSA) tape is developed where both the adhesive layer and plastic backing layer can be recycled back to monomer in a closed‐loop cycle. Both layers of the tape are composed of analogous polydisulfide copolymers using only two unique monomers, thus giving it a mono‐material design and enabling recycling of ...

Environmental pollution in the petroleum refining industry [PDF]
Analele Universitatii "Ovidius" Constanta - Seria Chimie, 2013 AbstractThe petroleum refining industry has a significant influence on the total pollution of the environment by industrial discharges and wastes. In the operation of petroleum refineries, the atmosphere is polluted with hydrogen sulfide, sulfur dioxide, nitrogen oxides, carbon monoxide, hydrocarbons, and other toxic substances. The main pollutants are
