Tar formation is one of the major problems to deal with during biomass gasification. Tar
condenses at reduced temperature, thus blocking and fouling process equipments such as …

An overview of the research on biomass upgrading by torrefaction for the production of
biofuels is presented. Torrefaction is a thermal conversion method of biomass in the low …

The efficiency of separation processes can usually be assured either by an energy input or
by external forces. The majority of conventional sep- arations applies mechanical or thermal …

Torrefaction is a thermal treatment step in the relatively low temperature range of 225–300C,
which aims to produce a fuel with increased energy density by decomposing the reactive …

Wood torrefaction is a mild pyrolysis process that improves the fuel properties of wood. At
temperatures between 230 and 300C, the hemicellulose fraction of the wood decomposes, so …

Torrefaction is a mild pyrolysis process carried out at temperatures ranging from 225 to 300C,
in which hemicellulose, the most reactive fraction of wood, is decomposed. Dehydration …

It is well known that the drag in a turbulent flow of a polymer solution is significantly reduced
compared to Newtonian flow. Here we consider this phenomenon by means of a direct …

Although biomass is getting increased attention as a renewable energy source, one of the
remaining problems still to be solved is the reduction of the high level of tar present in the …

The effect of fuel composition on the thermodynamic efficiency of gasifiers and gasification
systems is studied. A chemical equilibrium model is used to describe the gasifier. It is shown …

Biomass has great potential as a clean, renewable feedstock for producing modern energy
carriers. This paper focuses on the process of biomass gasification, where the synthesis gas …
