Autor: Lotfi Sellaoui, Éder Cláudio Lima, Guilherme Luiz Dotto, Silvio L.P. Dias, Abdelmottaleb Ben Lamine

Publikováno v: Results in Physics, Vol 7, Iss , Pp 233-237 (2017)

Two equilibrium models based on statistical physics, i.e., monolayer model with single energy and multilayer model with saturation, were developed and employed to access the steric and energetic aspects in the adsorption of reactive violet 5 dye (RV-

Caesalpinia ferrea: a potential feedstock for biochar production

Autor: Alexandre Bazzo, Heitor Luiz Ornaghi, Silvio L.P. Dias, Julio C.P. Vaghetti, Lucas Dall Agnol, Otávio Bianchi

Publikováno v: Biomass Conversion and Biorefinery.

In the present study, a lignocellulosic from inedible fruits of Caesalpinia ferrea (CFIF) — a tree mainly found in Brazil and Bolivia — was studied as potential biomass for production of biochar under different pyrolysis temperatures. The charact
