Analysis of catalytic control of tar quality during coal pyrolysis and the coke behavior on catalyst surface

Meitan xuebao
The low-rank coal pyrolysis technology with tar upgrading by catalyst is a clean and efficient coal conversion technology that ensures national energy security while also meeting the “carbon peaking and carbon neutrality” goals.

Effects of the reforming reagents and fuel species on tar reforming reaction

, 2009
In this study, using wood chips and polyethylene (PE) as fuels, the effects of air and/or steam as reagents on the tar reforming were clarified quantitatively with a simulated gasifier/reformer apparatus of a two-staged gasification process.

Characteristics of Pyrolysis Products of Tar-Rich Coal Under Cryogenic Pretreatment with Liquid Nitrogen

The conventional pyrolysis of tar-rich coals faces limitations in maximizing tar yield and optimizing tar composition, often resulting in inefficient resource utilization and elevated emissions of CO2.

Producing simulated tar-laden gasification gas by ethane pyrolysis

, 2014
One of the key issues in biomass gasification is the presence of tars in the product gas. Tar causes problems in downstream equipment by fouling and coke formation and thus, it needs to be removed.
