Rezumat:

The use of renewable resources has evolved considerably in the last period of time, mainly because of the fact that those resources are inexhaustible and they can be found at lower prices
on the market than the fossil fuels. From this category of resources, the biomass is one of the most important source of energy, being the first renewable resource that has been used to produce heat
on the stair of human evolution. Currently, biomass is used only for heating purposes, direct burning for cooking and hot water preparing sharing the largest part. About 95% of the biomass
currently used is firewood and agricultural waste, the rest is wood waste from industrial processes. Romania has a large biomass potential available for heat and electricity production especially from
the stock of wood and from agriculture.
The main purpose of this study is to present the types of biomass used in our days, their use in industry and also to present a model of installation used for transforming the biomass found in
agricultural residues in biogas. This model of installation is under construction at the Politehnica University of Timisoara and it’s main purpose is to create biogas using residues (sawdust, manure,
chopped leafes, etc) that will be mixed with water and acetic acid to realize the needed chemical reactions and will be introduced in two reactors by the means of a submersible pump. The use of this
kind of experimental installation will try to give a solution for solving the problem of obtaining the biogas from agricultural residues
