Leaching essentially removes metallic species from biomass and improves the quality of
pyrolysis products. However, common acid solutions, such as hydrochloric acid and acetic …

Pyrolysis converts lignocellulosic biomass into bio-oil, which result in at least four times with
more energy density than raw biomass. Bio-oil could be exploited in heating, power …

One of the main drawbacks of using biomass as pyrolysis feedstock consists of the huge
variability of the different biomass resources which undermines the viability of downstream …

Washing pretreatment is a promising method for upgrading biomass by removing alkali
metal and alkaline earth metals (AAEMs). In this study, three types of solution with different …

This work discloses how the pretreatment of wheat straw with acetic acid (AA) solutions
modifies the biomass composition, strongly affecting the pyrolysis product distribution. AA in …

Washing pretreatments of rice straw were performed using three different solutions, namely
water, dilute hydrochloric acid solution (HCl solution, pH= 2.9), and aqueous phase bio-oil …

Bio-oil undergoes phase separation because of poor stability. Practical application of
aqueous phase bio-oil is challenging. In this study, a novel approach that combines …

The liquid products obtained from pyrolysis of biomass include light bio-oil and heavy bio-
oil. The former contains large amounts of water and organic acids, while the latter contains …

In this study, six dominant organic compounds in biomass pyrolyzed bio-oil, composed of
acidic compound (acetic acid) and non-acidic compound (furfural, hydroxyacetone, ethylene …

In this study, three type of pretreatment methods (single pretreatment of leaching, single
pretreatment of torrefaction, combined pretreatment of leaching and torrefaction) were …
