The biomass production potential at temperate latitudes (56°N), and the quality of the biomass for energy production (anaerobic digestion to methane and direct combustion) were investigated for the green macroalgae, Ulva lactuca. The algae were cultivated in a land based facility demonstrating a production potential of 45T (TS) ha(-1) y(-1). Biogas production from fresh and macerated U. lactuca...

The general need to slow the depletion of fossil resources and reduce carbon footprints has led to tremendous effort being invested in creating "greener" industrial processes and developing alternative means to produce fuels and synthesize platform chemicals. This work aims to design a microwave-assisted cascade process for a full biomass valorisation cycle. GVL (γ-valerolactone), a renewable g...

The use of heterogeneous catalysis to upgrade biomass wastes coming from lignocellulose into higher value-added chemicals is one of the most explored subjects in the prospective vision of bio-refinery. In this frame, a lot of interest has been driven towards biomass-derived building block molecules, such as furfural. Gold supported catalysts have been successfully proven to be highly active and...

At the International Nickel Company (INCO) nickel refinery in Clydach, Wales, U.K., which has operated since 1901, 365 respiratory cancers, including 85 nasal cancers and 280 lung cancers, have occurred in workers since the 1920s. From 1901 to 1923, incidences of these cancers were high. In 1923, the refining process was changed, eliminating a nickel arsenide, Ni5As2, called orcelite, from the ...

Wastewater is not a liability, instead considered as resource for microbial fermentation and value-added products. Most of the wastewater contains various nutrients like nitrates phosphates apart from organic constituents that favor growth. Microalgae are unicellular aquatic organisms widely used treatment. Various cultivation methods such open, closed, integrated have been reported microalgal ...

in this paper, a modeling tool for risk assessment analysis of the movement of hydrocarbon contaminants in the vadose zone and mass flux of contamination release into the groundwater table was developed. also, advection-diffusion-reaction equations in combination with a three-phase equilibrium state between trapped air, soil humidity, and solid particles of unsaturated soil matrix were numerica...

PURPOSE Petroleum refinery workers are exposed to the carcinogens benzene and 1,3-butadiene. Declining exposures have been reported internationally but information on current exposure in the Swedish refinery industry is limited. The aim was to examine refinery workers' personal exposure to benzene and 1,3-butadiene and increase awareness of exposure conditions by collaboration with involved ref...

Solid acid catalyst plays a crucial role in the petroleum refinery industry and bio-refinery technology. In this work, p-phenolsulfonic (PSA) was successfully grafted onto surface of KH560-modified zirconium phosphate (K-ZrP) facile routine. The structure property organic-inorganic combined solid PSA/K-ZrP-x were characterized via XRD, FTIR, 13C solid-state NMR, TG, N2 adsorption-desorption, SE...

Edible oil extraction is a large and well-developed sector based on solvent assisted using volatile organic compounds such as hexane. The of from oilseeds generates volumes oilseed by-products rich in proteins, fibres, minerals secondary metabolites that can be valued. This work reviews the current status bio-macro-composition oilseeds, namely soybean, rapeseed, sunflower flaxseed, refining pro...
