چکیده
Co-refining of fast pyrolysis bio-oil together with fossil oil in existing refinery infrastructure is an attractive and cost-efficient route to conversion lignocellulosic biomass transportation fuel. However, due large differences properties between the two oils, special notice needed reduce process-related issues. Here, produced from was co-refined vacuum gas at a 20:80 weight ratio continuous operation pilot-scale slurry hydrocracker order investigate impact process parameters on product quality performance. Mass balances characterization were used yields, composition, hydrodeoxygenation. Best hydrodeoxygenation achieved using unsupported catalyst loading 900 ppm Mo either low temperature (410 °C) long residence time (2 h) or higher (435 shorter (1 h). These settings resulted about 94% but also led highest yield biogenic carbon phase (40–43 wt %) lowest fractions (53–56 as well water fraction (3–5 %). Successfully, coke remained around 0.07–0.10 % for all performed runs, which comparable insoluble particle content feed presence particles untreated bio-oil. Co-processing seems be robust regard formation, should lead reduced plugging issues compared fixed bed hydrotreaters. Although this study gives brief understanding effect processing bio-oil, further research required find optimal fully comprehend possibilities limitations production fuels technology.

Biofuels from continuous fast pyrolysis of soybean oil: a pilot plant study.
The continuous fast pyrolysis of soybean oil in a pilot plant was investigated. The experimental runs were carried out according to an experimental design alternating the temperature (from 450 to 600 degrees C) and the concentration of water (from 0% to 10%). The liquid products were analyzed by gas chromatography and by true boiling point (TPB) distillation. A simple distillation was used to o...

Fast Pyrolysis of Lignins
Three lignins: Indulin AT, Lignoboost, and Acetocell lignin, were characterized and pyrolyzed in a continuous-fed fast pyrolysis process. The physical and chemical properties of the lignins included chemical composition, heat content, ash, and water content. The distributed activation energy model (DAEM) was used to describe the pyrolysis of each lignin. Activation energy distributions of each ...
