Fan, Yuyang; Tippayawong, Nakorn; Wei, Guoqiang; Huang, Zhen; Zhao, Kun; Jiang, Liqun; Zheng, Anqing; Zhao, Zengli; Li, Haibin published the article 《Minimizing tar formation whilst enhancing syngas production by integrating biomass torrefaction pretreatment with chemical looping gasification》. Keywords: syngas production chem looping gasification biomass torrefaction pretreatment.They researched the compound: 5,6-Dihydro-2H-pyran-2-one( cas:3393-45-1 ).HPLC of Formula: 3393-45-1. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:3393-45-1) here.
The objective of this study is to investigate the effect of torrefaction pretreatment on the syngas production and tar formation from chem. looping gasification (CLG) of biomass over different oxygen carriers. The torrefaction of eucalyptus wood and subsequent CLG were systematically studied by using the fixed bed reactors coupling with various anal. methods. The exptl. results demonstrate that torrefaction played significant impacts on CLG of eucalyptus wood using iron ore as an oxygen carrier. The gas yield and carbon conversion efficiency from CLG of eucalyptus wood were lowered by torrefaction, while the tar content was evidently reduced from 43.6 to 17.6 g/Nm3. These results could be due to the devolatilization, polycondensation, and carbonization of eucalyptus wood during torrefaction, resulting in the formation of fewer tar precursors and more char with lower reactivity during subsequent CLG. The neg. impacts of torrefaction on the gas yield and carbon conversion efficiency of CLG can be effectively overcome by the selection of suitable oxygen carriers. Five metallic ferrites were successfully synthesized and used to replace iron ore for CLG of torrefied eucalyptus wood obtained at 280°C. It is found that NiFe2O4 reduced the tar content by 88.8% and improved the gas yield by 27.5% compared to CLG of untreated eucalyptus wood over iron ore. These results suggest that integrating biomass torrefaction pretreatment with CLG is an efficient strategy for enhancing syngas production while minimizing tar formation.
There is still a lot of research devoted to this compound(SMILES：O=C1C=CCCO1)HPLC of Formula: 3393-45-1, and with the development of science, more effects of this compound(3393-45-1) can be discovered.
