Production Characteristics

The in situ technique forms the basis of many feed evaluation systems for ruminants. Although this method is widely used, the NBT is very laborious, time-consuming, and incubations and analyses of the feed residues often last several weeks. Therefore, several other techniques have been investigated to measure and predict ruminal degradation of various chemical components of feedstuffs. The aim of this study is to investigate the possibilities of estimating in situ degradation characteristics of DM, CP, ADF and NDF in several feedstuffs by gas production characteristics and chemical composition.

In order to understand the behavior of biomass pyrolysis, a series of pretreatment biomass were prepared with acid-washing and metal impregnated methods. The effects of metal ions on the yields of tar, char and gas from straw pyrolysis were analyzed in our lab scale fixed-bed reactor. Alkali metal and alkaline earth metal ions affect biomass pyrolysis process and the products heavily. The decreasing metal ions result in declining yield of semi-char and increasing yields of tar and gas. Meanwhile, the pyrolysis temperature corresponding maxium yield of tar increases. There exist marked catalytic effect of potassium, calcium and magnesium cations on the cracking of large molecular weight parts of tar and semi-char formation via recombination reaction of tar. As cause a higher production of char while a decrease of tar and gas production.

This contribution describes a design of experime ntal reactor for decomposing the process of gasses with different contents of hydrocarbons (CH 4 , C 2 H 4 , C 2 H 6 , C 3 H 6 , C 3 H 8 ) . It shows pyrolysis process as a possible source for synthesis gas production . The mathematical modeling ( Ansys Fluent) was used to predict maximal temperature and velocity in three designs and the best result was chosen for manufacturing. Optimal dimensions and material s were chos en basing on the analysis. The ch emical analysis is a second step of research and it is not used in this article .
