H2 production by sorption enhanced steam reforming (SESR) of bio-oil/biogas blends was demonstrated in a fluidized bed reactor. It combines (SR) with simultaneous CO2 capture solid sorbent. SESR performed on Pd/Ni-Co catalyst derived from hydrotalcite-like material (HT) using dolomite as Bio-oil fast pyrolysis biomass is carbon–neutral and renewable energy source great potential for clean proce...

in this study, a bacterial species which could remove lead from wastewater was isolated from lead contaminated soil prepared in the laboratory. based on the biochemical and morphological characterization the bacteria were identified as brevundimonas vesicularis. the biosorption potentiel of powdered dry biomass of b. vesicularis was investigated by batch adsorption experiments. it was found tha...

Bio-oil includes significant levels of oxygenate molecules, which might induce component instability and reduce its physicochemical qualities. To counteract this, the must undergo a hydrodeoxygenation (HDO) reaction. Due to presence acidic active sites, zeolites have been shown high hydrogenation deoxygenation capabilities. However, natural zeolite has large number impurities low acidity densit...

Bio-based surfactants have attracted increasing attention due to their renewable resources and excellent surface properties. In this study, a novel bio-based sulfonic zwitterionic surfactant (BSZS) derived from transgenic soybean oil was prepared using a simple reaction route with two steps of the amidation and quaterisation. The bio-based sulfonic zwitterionic surfactant showed a critical mice...

In this study, the pyrolysis procedure was used to extract oil from pomegranate peels (PP) utilizing biomass-derived sulfonated tea waste as a catalyst. FTIR, SAA, SEM, and XRD were characterize Thermo-catalytic decomposition carried out in salt bath reactor bio-oil composition determined through GC-MS. The obtained virgin PP observed contain compounds range of C5–C13, whereas catalyzed reactio...

Fast pyrolysis bio-oil is very difficult to be used because of its acidity, instability, high degree unsaturation, etc. Processes for property upgrading are necessary and required. In this study, three kinds Raney Ni catalysts were prepared investigate two-step esterification–hydrogenation (TEH) upgrade the light fraction bio-oil. The results show that first step in esterification markedly decr...

Several diesters were prepared from commercially available oleic acid and common organic acids. The key step in the three step synthesis of oleochemical diesters entails a ring opening esterification of alkyl 9,10epoxyoctadecanoates (alkyl: propyl, isopropyl, octyl, 2ethylhexyl) using propionic and octanoic acids without the need for either solvent or catalyst. Each synthetic diester was evalua...

Cellulose hydrolysis to glucose using a heterogeneous catalyst is necessary step in producing bio-based chemicals and polymers. The requirement for energy-intensive pretreatments, such as ball milling, increase the reactivity of cellulose one major issues this area. Here, we show that by solvent-assisted adsorption pretreatment step, can be adsorbed on surface carbon catalyst. For pretreatment,...

The gas-phase hydrodeoxygenation (HDO) of furfural, a model compound for bio-based conversion, was investigated over transition metal phosphide catalysts. HDO activity decreases in the order Ni2P ? MoP > Co2P WP ? Cu3P Fe2P. Nickel phases (e.g., Ni2P, Ni12P5, Ni3P) are most promising catalysts furfural HDO. Their selectivity to gasoline additives 2-methylfuran and tetrahydro-2-methylfuran can b...
