In this paper we assume determination of pseudo-viscosity coefficients of visco-elastic non-Newtonian fluid flow directly near the cooperating micro-bearing surface. We show the constitutive stress-strain dependencies of nonNewtonian visco-elastic media with regard to the content of addition of nano-particles. The greater content of nano-particles and influences of superficial layer of cooperat...

The exponential increase of plastic production produces 100 million tonnes of waste plastics annually which could be converted into hydrocarbon fuels in a thermal cracking process called pyrolysis. In this research work, a direct current (DC) thermal plasma circuit is designed and used for conversion of low density polyethylene (LDPE) into diesel oil in a laboratory scale pyrolysis reactor. The...

This study focuses on how wave–current and wave–turbulence interactions modify the transport of buoyant particles in the ocean. Here the particles can represent oil droplets, plastic particles, or plankton such as fish eggs and larvae. Using the General Ocean Turbulence Model (GOTM), modified to take surface wave effects into account, we investigate how the increased mixing by wave breaking and...

Palm oil is one of the two most important vegetable oils in the world’s oil and fats market. The extraction and purification processes generate different kinds of waste generally known as palm oil mill effluent (POME). The environmental impact of POME cannot be over emphasized; hence the need for treatment measures to reduce these impacts before discharge. Therefore, this paper reviews the proc...

The increasing use of conventional plastic has been creating some big problems, ranging from the oil crisis as a raw material for production and accumulation unbiodegradable waste on earth. One promising measures to handle problem is environmentally–friendly biodegradable plastic, made renewable materials. aim this project characterize properties bio-plastic banana peel. process begins with ext...

Finding a proper way to manage the enormous amount of waste plastic that is globally produced, one main environmental challenges our times. Among different types chemical recycling, Hydrothermal Liquefaction (HTL) appears as potential method for treatment mixes, sustainable production biocrude or chemicals with high added value. In this work hydrothermal liquefaction reactions were carried out ...

The catalytic and thermal decomposition of plastic waste to fuels over low-cost catalysts like zeolite, clay, bimetallic material is highlighted. In this paper, several relevant studies are examined, specifically the effects each type catalyst used on characteristics product distribution produced products. plays an important role in oil yields quality. addition, quality yield products depend fa...
