The performance of Fe/olivine catalysts was tested in the continuous steam gasification sawdust a bench scale plant provided with fountain confined conical spouted bed reactor at 850 °C. Olivine used as catalyst support and loaded 5 wt%Fe. activity stability monitored by nitrogen adsorption-desorption, X-ray fluorescence spectroscopy, temperature programmed reduction, diffraction photoelectron ...

Effective gas dispersion and liquid mixing are significant parameters in the design of an inert-particle spouted-bed reactor (IPSBR) system. Solid particles can be used to ensure good efficient rate mass heat transfer between liquid. In this study, computational fluid dynamics (CFD) coupled with discrete phase model (DPM) were developed investigate effect feed velocity (0.5–1.5 m/s), orifice di...

The corrosion performance of alloys in coal gasification systems is of increasing industrial interest as more advanced coal-fired power generating systems are developed. It is necessary to consider the performance of candidate materials under likely exposure conditions to ensure that components have adequate lifetimes. Materials performance can influence the economic feasibility of these system...

During these last years, many investigations have been made on sulphur elimination processes from hydrocarbon feedstocks because of environmental regulations which are more and more strict. This is a study on a plasma process dedicated to heavy hydrocarbon hydrotreatment and hazardous substances removing such as sulphur compounds. It is a co-processing of a fluidized spouted bed and an inductiv...

The central aim of this thesis is to support the efforts to counteract certain environmental problems caused by emissions of volatile organic compounds. The purpose of this work was (1) to develop a method to measure emissions from dryers, (2) to determine the effect of drying medium temperature and end moisture content of the processed material on emissions of monoterpenes and other hydrocarbo...

Fruit mixed pulp has the objective of improving nutritional and sensorial characteristics, as well development new flavours aromas. Different methods drying (e.g., spray-drying, spouted bed drying, freeze-drying) can influence quality final product. The this study was to select method that enables production acerola-ceriguela (ACMP) with higher quality. For selection, powder pulps were evaluate...
