Petroleum products are very flammable and can ignite at extremely low temperatures if exposed to an open flame source or not handled appropriately. Individuals who handle petroleum in the industry fuelling stations known as "petrol station attendants". The study was a descriptive cross-sectional carried out among petrol attendants working filling owned by independent marketers Sapele ...
(Ligno)cellulose is mainly composed of cellulose, lignin, hemicellulose, and extractives, which represents an abundant carbon-neutral renewable resource. Increasing concerns about global warming and diminishing fossil fuel reserves have stimulated much effort to use (ligno)cellulose as an alternative to petroleum for the production of fuels and chemicals. From a sustainability point of view, sh...
increasing academic and professional language demands around the world are not a deniable fact. the purpose of this study was to investigate english language needs and communication needs of the chemistry students at master and ph.d. levels at the iranian universities. in this research, different methods were used including un-structured interview, structured interview, and two sets of question...
Fluid Catalytic Cracking (FCC) is a major refinery process designed to upgrade heavy and less valuable petroleum products to gasoline and lighter products. The feedstock for the FCC process ranges from light gas oils to heavy hydro-treated resids. The complexity of the feedstock, and the associated analytical chemistry and computational obstacles, helped shape early FCC modeling approaches (2.3...

Efficient scrubbing of mercury vapour from natural gas streams has been demonstrated both in the laboratory and on an industrial scale, using chlorocuprate(II) ionic liquids impregnated on high surface area porous solid supports, resulting in the effective removal of mercury vapour from natural gas streams. This material has been commercialised for use within the petroleum gas production indust...

Sustainable Chemistry The cover image for article number 2100391 by Siegfried R. Waldvogel and co-workers represents a method to obtain selectively 5-iodovanillin, as an advanced building block, from side-stream lignins degradation using electrochemically generated periodate. In times of climate changes the utilization lignin renewable feedstock fine chemicals is considered, would rival petrole...
