The porous materials, hollow silica (HSC) and activated carbon (AC), were selected to investigate their effects with water on methane hydrate formation and dissociation. The methane hydrate formation with the porous materials ...

This research was aimed to synthesize intermetallic catalysts using mechanical alloying (Ma) technique. Copper (Cu) and nickel (Ni) were chosen to study since not only their properties are closed to the noble metal properties, ...

The waste treatment and disposal of oil refining industry sector are one of the significant aspects of environmental concerns. Because they are not only generated in substantial amounts, but also contained with various ...

Energy and Exergy analysis are one of alternative techniques to analyze chemical processes in term of energy quality parameters such as enthalpy, entropy and exergetic temperature. The exergetic temperature can conduct ...

Porous Clay Heterostructure (PCH) is an interesting material to use as entrapping system such as ethylene scavenger, respected to its high surface area with uniform and specific pore size. PCHs have been prepared by the ...

This work studied the conversion of lignocellulosic materials to sugars, the intermediates for bioethanol production, by a bacterial enzyme. Due to the complex structure of lignocellulose, a cellulase enzyme cannot effectively ...

Oil spills have become a global problem. This is one of the serious problems in marine environment. The spills are generally from reservoir zipping, accident or unauthorized drainage. Typically, the spilled oils are fuel ...

This research focuses on how to use natural fibers available from agricultural residues to produce biodegradable materials such as mulch films. Green composites were prepared from natural fibers (peanut shell and bagasse ...

Methyl palmitate or palmictic acid methyl ester was used as both a model solid fat and an oily soil was removed from cotton and polyester above and below the melting point. Surfactants studied were extended surfactants ...

The formation of the incipient layer of wax deposit when waxy oil is exposed to a cold surface is studied. Using a cold-finger apparatus, the evolution of deposit thickness is monitored with a video camera, allowing one ...
