Biomass as Renewable Source of Energy, Possible Conversion .

In fixed-bed reactors (Fig. 7), the biomass feedstock is exposed to the gasifying agent in a packed bed that slowly moves from the top of the gasifier to the bottom, where the ash is discharged. Fixed-bed gasifiers are dense-phase gasifiers. They are characterized by a relatively large amount of fuel exposed to a limited amount of reactive gas.

Development of fixed bed reactor for application in GTL .

Oct 14, 2019 · The FTS reactions over Ru/Co/Al 2 O 3 catalyst were performed in the shell and tube type fixed-bed reactor with an oil circulation system in order to investigate the effect of N 2 and CO 2 content. It was found that the N 2 gas does not affect the product selectivity of the FTS reaction over Ru/Co/Al 2 O 3 catalyst in the fixed-bed reactor at pilot scale but it has decreased the CO conversion.

Aug 16, 2016 · Water is of fundamental importance for life on earth. The synthesis and structure of cell constituents and transport of nutrients into the cells as well as body metabolism depend on water. The contaminations present in water disturb the spontaneity of the mechanism and result in long/short-term diseases. The probable contaminations and their possible routes are discussed in the present review.
