The Production of a Fuel Gas with High Content of Hydrogen through Biomass Gasification

Abstract:

An installation of biomass gasification in fixed bed and downstream circulation was realized to obtain a fuel gas with high content of hydrogen. A particularity of this gasifier is considered to blow in the gasification agent in the middle of the gasifier hight, the reduction zone is situated beneath the oxidation zone. In this way the biomass humidity and all the products of dry distillation are cracked passing through the oxidation zone. The obtained gases pass through the reduction zone where take place the basis reactions of the gasification. The gas produced in this way does not contain volatile substances, only a small quantity of water and solid particles easy to be released. As raw material were used agricultural wastes (pellets of sunflower waste). As gasification agents were used steam and air. To have a higher content of hydrogen in the obtained gasifier gas was introduced in the gasification reactor an air rich in oxygen. For a certain content of oxygen in the air used as gasification agent is recorded the composition of the gasifier gas and is followed the hydrogen content. The realized experiments have as purpose repeated tests, in such number to obtain concluding data for the efficiency in obtaining a gasifier gas rich in hydrogen, for a long period of time. There are also presented the results from the experiments (3-5 experiments for each composition of the gasification agent). Keywords: biomass gasification, hydrogen, renewable technologies
