Abstract The review examines the subject matter of catalytic pyrolysis, which is an upgrade on both operation and output thermal pyrolysis process, capable producing liquid oil products a higher quality yield compared to at reduced energetic demands. use catalysts plays major role in increasing cracking activity subsequent decomposition reactions, attaining more desirable aromatic products. pro...

The present study investigated the coupling effect of biodegradation and media filtration in treating hydrocarbon contaminated water. The study recorded reductions in total petroleum hydrocarbon, total dissolved solids, turbidity and microbial load. The study was essentially a simulated pump and treat process that involved the pumping of hydrocarbon contaminated water for treatment in a locally...

The demand for technological and industrial change has become heavily dependent on the availability use of petroleum products as a source energy socio-economic development. Notwithstanding, petrochemical are strongly related to global economic activities, their extensive distribution, refining processes, final routes into environment pose threat human health ecosystem. Additional environmental ...

The Mishrif reservoir (Cenomanian - Turonian) in the Z, H, B and N oilfields southern Iraq was investigated to clarify how nickel, vanadium, asphaltene, NSO sulfur content affect crude oil quality. GC-Mass ICP-MS analyses were used provide fruitful hydrocarbon results. Classification of based on API gravity broadly indicates oil's density general properties. Typically, lighter oils are easier r...

the present study was carried out to investigate the effect of various refining processes’ conditions on conjugated dienes in soybean oil. conjugated dienes contents of soybean oil were found to undergo reduction in neutralization and bleaching steps while being increased in deodorization. it was observed that alkali refining (neutralization) through 12 and 14 °bé, bleaching with either acid ac...

The upgrading of diesel oil to produce ethylene rich cracking feedstock is an important and promising technical route reduce the ratio gasoline. In present work, a hydrocracking catalyst suitable for selective straight run high-quality at low cost was developed, by optimizing composition support materials, using amorphous silicon aluminum oxide with high mesopore content as main support, modifi...

contamination of soil was investigated in this study from the tehran oil refining co. of iran. fifteen soil samples were collected at several points in the azimabad, 15 km south of tehran city, iran. samples were collected at depths of 0–30 cm. control sampleswere prepared to determinebackgroundlevels ofsoil contaminationwithpetroleumhydrocarbonsfor comparison with contaminatedsites. total petr...

Oily wastewater is generated from various sources within the petrochemical industry, including extraction, refining and processing, storage, transportation. Over years, large volumes of oily this industry have made their way into environment, negatively affecting human health, economy. The raw waters can differ significantly complex features, making them difficult to treat. Membrane bioreactors...
