Study on the distribution law of co-pyrolysis products of tar models and sawdust

能源环境保护
In this study, toluene and acetic acid were investigated as model biomass tars, and sawdust was used as the feedstock. Co-pyrolysis experiments were conducted in a first-order fixed-bed reaction system to maximize the tar removal from sawdust.

Investigation of coal pyrolysis tar of Aduunchuluun deposit

Bulletin of Institute of Chemistry and Chemical Technology, Mongolian Academy of Sciences, 2018
The generated products of heating of coal in airless condition are hard residue, condensed liquid and gas. The condensed liquid product or tar is one of the most important product of pyrolysis. Therefore detailed investigation on pyrolysis of brown coal and it is tar studies provide basic theoretical knowledge for further thermal processing and ...

A method for reducing the tar content in pyrolysis gas [PDF]

, 2019
Disclosed is a method for reducing the tar content in pyrolysis gas generated in a pyrolysis reactor (1). The method comprises the steps of: guiding the pyrolysis gas through a filter (2) to remove at least 90% of all the particles in the pyrolysis gas having a particle size down to 7 μ and preferably down to 4 μ from the pyrolysis gas, partially ...

Preparation of Nitrogen-Rich Tar by Co-Pyrolysis and Analysis of Nitrogen-Containing Compounds in Pyrolysis Products

Applied Sciences
In this study, we use coal as a carbon source from Zhangjiamao and doped with different nitrogen sources for co-pyrolysis. Nitrogen-rich tar was successfully prepared, and the content and variety were also increased.

Tar and soot generation behaviors from ABS, PC and PE pyrolysis [PDF]

, 2017
In this study we performed a non-isothermal thermogravimetric analysis on three thermoplastics—ABS, PC and PE. The Coats and Redfern method (Nature 201:68–69, 1964) was then used to approximate the kinetic parameters of each material.

A kinetic approach to catalytic pyrolysis of tars

Fuel Processing Technology, 2001
Abstract A kinetic model to describe the catalytic pyrolysis of tars is proposed and validated through the experimental pyrolysis of three tars of different characteristics and origin; calcined limestone (11 m 2 /g) was used as catalyst. Experiments were carried out in a catalytic fixed bed reactor.
