The effect of temperature and catalyst concentration on palm oil ethanolysis using 0.2 to 1 wt% NaOH based on the mass of palm oil was studied at temperatures ranging from 60 to 80 °C, keeping constant the ethanol to oil molar ratio (6:1). A 100% conversion of palm oil and a 96% yield of FAEE...

The study performed aimed at analysing possible routes for pyrolysis reaction mechanisms of polymeric materials namely RT (rubber tyre) and plastic wastes (PE (polyethylene), PP (polypropylene) and PS (polystyrene)). Consequently, and seeking sustainable transformation of waste streams into...

The influences of alkali and alkali–earth salts on the combustion of municipal solid waste (MSW) have been studied by thermogravimetric analysis (TGA). In the presence of alkali and alkali–earth salts, the combustion of MSW become easier than that of non-catalyzed MSW. By comparing the...

This paper deals with the technical feasibility of calcium oxide as a sorbent for CO2 (carbon dioxide) in syngas for air–steam gasification of lignocellulosic biomass. The process is simulated through a kinetic approach incorporating rate equations for the component reactions. Using the...

Pyrolysis of tert-butanol (2.77% tert-butanol in argon) in a laminar plug flow reactor was studied at low pressure and a temperature range of 950–1850 K. More than 20 pyrolysis species were identified by using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS); and...

Watershed management is dedicated to solving watershed problems on a sustainable basis. Managing watershed development on a sustainable basis usually entails a balance between the needs of humans and nature, both in the present and in the future. From a watershed or water resources development...
