The objective of this research was to examine the effects of micro aeration on the separate hydrogen and methane production from ethanol wastewater using a two-stage up flow anaerobic sludge blanket reactor (UASB) system, ...

In biodiesel production, typical homogeneous catalyst for transesterification of vegetable oil are basic solutions, such as KOH, NaOH or NaOCH3. After the reaction, the remaining catalyst in the product must be neutralized ...

Heat integration and HEN synthesis, which is a heuristic approach to utilize energy efficiently and economically, has been widely used either in the petroleum or petrochemical industries. Therefore, there are many innovations, ...

This study aims to conduct life cycle assessment (LCA) of compressed biomethane gas (CBG) in terms of both energy and environmental aspects. The system boundary was set to cover all processes throughout the entire life ...

p-Xylene is the most important intermediate in xylene isomers. It is mainly used for producing terephthalic acid. Currently, p-xylene is produced by disproportionation of toluene and p-xylene-oriented isomerization of mixed ...

Sodium chloride and polyethylene glycol (PEG) were used as water-soluble porogens for the formation of porous polycaprolactone (PCL) and their blends scaffolds. The main purpose was to prepare and evaluate in vitro efficacy ...

The conversion of biomass-derived alcohols (methanol, ethanol, n-propanol and n-butanol) to hydrocarbons over modified HZSM-5 (30) at 450 ℃ and atmospheric pressure under nitrogen flow using a fixed bed flow reactor was ...

Poly o-anisidine (POA) is a conductive polymer that can conduct electrons by a π - conjugated system. POA is a derivative of polyaniline, however, it still exhibits low electrical conductivity. This work is focused on the ...

The sulfonated lignin catalysts were used as the catalyst in biodiesel production via esterification from oleic acid. The sulfonated lignin catalysts are prepared by 2 steps. First, lignin is extracted from the pretreatment ...

Mission grass (Pennisetumpolystachion) is one of the lignocellulosic biomass candidates for the production of bioethanol. After the grass underwent through milling and alkaline pretreatment, it was subjected to acid and ...
