<p>This research focuses on hydrothermal gasification (HTG) and liquefaction (HTL) studies to produce bio-hydrogen from domestic mixed waste. HTG HTL were studied at temperatures of 300–450°C 300–400°C, correspondingly, with a catalyst level 6 wt %. The sol-gel technique was used make the Bentonite/Nb-TiO2 catalyst. For solvent-waste proportion 14 millilitre/gram, an C2H5OH - water propor...

The effect of catalyst loading in the Aqueous Phase Reforming (APR) bio-oil aqueous fraction has been studied with a Ni-Co/Al-Mg coprecipitated catalyst. Because high content water fraction, APR could be useful process to convert this into valuable products. Experiments continuous feeding solution acetol, butanol and acetic acid as only compound, together simulated real bio-oil, were carried ou...

Since the discovery of ruthenium as a catalyst for hydrogenation reactions, Ru catalysts have been widely used in the chemical, petrochemical, food, and pharmaceutical industries, and in energy-conversion technologies. The scope of homogeneous Ru catalysts has been well-illustrated recently. However, heterogeneous catalysts can be preferable from both industrial and environmental perspectives. ...

Bio-based plastics were designed to replace single-use and cause less post-consumer environmental damage. This paper assesses the weathering of four bio-based polymers created by ring opening polymerization (ROP) promoted a previously reported Ti-based catalyst, detect any problems before production was scaled up. Samples aged in seawater identify degradation products monitor structural changes...

Kraft lignin is efficiently depolymerized under benign conditions into value-added aromatics and high-quality bio-oil using a facile vanadium–copper catalyst system.

Taxol is recognized as one of the most potent anticancer agents used in the treatment of breast and ovarian cancers, which are common cancers in women. To overcome its shortcomings, that is, its low water-solubility that reduces drug loading capacity of DDS carriers when incorporating taxol, chemo-enzymatic synthesis of ester-linked taxol-glucose conjugate, i.e., 7-propionyltaxol 2″-O-α-D-gluco...

The major challenge for the pyrolytic conversion of lignocellulosic materials into crude bio-oil is the poor quality of the final product. Several strategies (addition of solvents, production of emulsions, and extraction with biodiesel) have been studied to improve its fuel properties. The extraction with biodiesel is an interesting solution because it allows direct utilization of some bio-oil ...

Abstract Bioenergy sources continue to be developed solve environmental problems due agricultural biomass waste and alternative energy sources. from raw materials through the pyrolysis method is a thermochemical conversion technology that produces bio-oil bio-char. The process of coconut shell (CS) with size 60 mesh at temperature 500-700°C without adding catalyst. results showed optimum decomp...

Hydrogen produced from renewable energy sources can present significant environmental benefits as an alternative to fossil fuels or as a means for clean power generation via fuel cells. The aqueous fraction of bio oil can be used as a source for hydrogen production, if reformed in the presence of active catalytic materials. Recently, we introduced the concept of the spouted bed reactor for the ...
