The objectives of this project are to support the DOE direct coal liquefaction process development program and to improve the useful application of analytical chemistry to direct coal liquefaction process development. Independent analyses by well-established methods will be obtained of samples...

The practical application of PCB (polychlorinated biphenyl) analyses begins with a request for the analysis and concludes with provision of the requested analysis. The key to successful execution of this iteration is timely, professional communication between the requester and the analyst. Often...

A very good understanding of the structure, level, type and physical property relationships of fatty acids in plants oils and their methyl esters (FAMEs) is of utmost importance when selecting vegetable oils for a particular desired biodiesel quality that meets the operating condition...

The subject of this work was the investigation of zeolite as a sorbent of toxic gases. In Nizny Hrabovec in the Slovak republic, two layers of zeolite with the active component clinoptilolite can be found. The study presented here investigated the ability of this natural zeolite to reduce...

This study investigates the effect of direct sonication in conversion of waste cooking oil into biodiesel. Waste cooking oils may cause environmental hazards if not disposed properly. However, waste cooking oils can serve as low-cost feedstock for biodiesel production. Ultrasonics, a...

Die Wirkungen von Stoffströmen sind abhängig von der umgesetzten Menge und denspezifischen Auswirkungen pro Mengeneinheit. Die Menge der Extraktion an Primärmaterialaus der Umwelt kann als vorsorgeorientierter Indikator für ein unspezifisches Umweltbelastungspotential herangezogen werden....

The aim of this study is to understand long and short-run linkages between economic growth, energy consumption and carbon emission using Tunisian data over the period 1971-2004.Cointegration procedure is used to analyze the time series properties of the series and error-correction terms were...
