The effects of alkalinity on alkaline hydrothermal conversion (alkaline-HTC) of cellulose to bio-oil were investigated in this study. The results showed that the initial alkalinity greatly influenced the reaction pathways. Under initial strong alkaline conditions with final pH greater than 7, alkaline-HTC only followed the alkaline pathway. However, under initial weak alkaline conditions with f...

The feasibility of co-producing activated carbon and bio-oil from rice stalk through molten salt pyrolysis is reported in this work. The results indicated that: (1) mixed ZnCl2-KCl molten salt could considerably improve the solid and liquid yield as well as the ratio of H2 and CH4 selectively (compared to the traditional ZnCl2 method), (2) an increase of pyrolysis temperature had the same impac...

The reciprocating biomass conversion reactor (RBCR) is a novel means to produce bio-oil by fast-pyrolysis whose core is a re-purposed 4-cycle internal combustion engine. An inert gas and a small volume-fraction of pulverized biomass are input into the RBCR intake, and the crankshaft is cycled by an external energy source to supply the process heat. The biomass is converted during the compressio...

A 2D Euler-Euler multiphase computational fluid dynamics (CFD) model in conjunction with the kinetic theory of granular flow (KTGF) was applied to describe biomass pyrolysis a spouted bed reactor. The primary interest this work development CFD hydrodynamic reactor coupled for prediction product yields (gas, bio-oil, and char). is based on three parallel reactions formation products secondary re...

Background Biofuels from hydrothermal liquefaction (HTL) of abundantly available forest residues in British Columbia (BC) can potentially make great contributions to reduce the greenhouse gas (GHG) emissions from the transportation sector. A life-cycle assessment was conducted to quantify the GHG emissions of a hypothetic 100 million liters per year HTL biofuel system in the Coast Region of BC....

Abstract Pyrolysis is a thermochemical process commonly used for bio-oil, bio-char, and syngas production. It particularly attractive due to its cost-effectiveness low environmental impact. Therefore, this study utilizes coffee waste produce activated carbon in slow pyrolysis reactor at different reaction temperatures residence times. The results obtained show that bio-oil yields tend increase ...

The aim of the present investigation was to assess and compare the antimicrobial activities of the lemon (Citrus sinensis) peel extract and lemon oil against common food borne pathogens and to study their potential as food bio-preservatives. The antagonistic activity of lemon peel extract and lemon oil was studied against common food borne pathogens like Staphylococcus aureus, Staphylococcus ep...

Development and application of bio-based fluids in industrial and automotive sectors are rapidly increasing due to their non-toxic and biodegradable character unlike mineral oil-based products. Synthetic lubricant base fluid with improved high and low-temperature stability was prepared by chemical modification of epoxidized soybean oil (ESBO). The reaction was carried out in two-steps: (i) synt...

Este trabajo se enmarca en un proyecto cuyo objetivo es desarrollar método de fraccionamiento para separar el bio-oil producido la pirólisis biomasa fracciones más homogéneas respecto a tamaño molecular y polaridad. Para ello han utilizado las técnicas Cromatografía Líquida Flash Capa Fina aplicadas compuestos fenólicos presentes habitualmente bio-oil.
