چکیده
In this article, activated carbon was produced from Lantana camara and olive trees by H3PO4 chemical activation. The prepared carbons were analyzed characterizations such as scanning electron microscopy, energy-dispersive X-ray spectroscopy, Brunauer–Emmett–Teller, diffraction, thermogravimetric analysis, Fourier transform infrared spectroscopy. is used an activator agent to create abundant pore structure. According EDX the crystalline structure destroys increases content of tree 77.51 76.16%, respectively. SEM images reveal a porous formed result Brunauer–Emmett–Teller (BET) surface area 611.21 m2/g 167.47 m2/g, TGA analysis both shows their thermal degradation starts at 230 °C but fully degrades temperatures above 450 °C. To quantify potential environmental implications related production process (AC) trees, life cycle assessment (LCA) methodology employed. For most tested indicators, activation using showed greatest ecological impacts: ozone layer depletion (42.27%), acidification (55.31%), human toxicity (57.00%), freshwater aquatic ecotoxicity (85.01%), terrestrial (86.17%), eutrophication (92.20%). global warming (5.210 kg CO2 eq), which evenly weighted between phases, shown be one significant impacts. total energy demand tree’s AC producing 70.521 MJ per Kg.

assessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...

Conventional steam activation for conversion of oil palm kernel shell biomass into activated carbon via biochar product
Conventional steam activation pyrolysis of waste materials such as oil palm kernel shell for production of biochar was investigated using central composite design. Conventional steam activation was carried out via an initial carbonization of oil palm kernel shell to obtain biochar and thereafter steam activation of the biochar using the conventional heating to produce activated carbon. Addition...
