Granular Bed Filtration of Coal Pyrolysis Gas: Effects of Media Reactivity on Dust Removal and Products

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Granular bed filtration is a promising technology for removing dust from high‐temperature coal pyrolysis gas. In this work, the reactivity of coal pyrolysis products over ceramsite, char, ultrastable Y‐type (USY) zeolite, and quartz particles was compared.

Combustion characteristics of bamboo-biochars

Bioresource Technology, 2014
Combustion characteristics of biomass are very important to directly utilize as an energy resource. Bamboo was carbonized using a XD-1200N muffle furnace in the nitrogen environment and its combustion characteristics were investigated. Results showed that bamboo-biochars had better combustion characteristics compared to bamboo materials, such as a ...

Combustion Characteristics of Seaweed Biomass. 1. Combustion Characteristics of Enteromorpha clathrata and Sargassum natans

Energy & Fuels, 2009
The fuel characteristics of two typical seaweeds (Enteromorpha clathrata and Sargassum natans) were studied. It was found that both the contents of volatile and ash are high, and the ash melting characteristics were different. High contents of alkali metals especially K and Na were also found in seaweed ash.

Combustion Characteristics of Boron Nanoparticles

46th AIAA Aerospace Sciences Meeting and Exhibit, 2008
Abstract An experimental investigation of the combustion characteristics of boron nanoparticles in the post flame region of a flat flame burner has been conducted. Boron is attractive as a fuel or a fuel supplement in propellants and explosives due to its high heats of combustion on both a gravimetric and volumetric basis. A relatively large database
