IOP Conference Series: Earth and Environment, 2019 The “hot-cold baths” impregnation of birch wood samples by a number of oils (original engine oil, waste motor, spent transmission, spent corn and sunflower oils) were studied in order to choose a base for impregnating composition. Specimens of wood flour

The Effect of Microwave Pretreatment on the Impregnation of Poplar Wood
BioResources, 2014 Microwave pretreatment can increase the transverse permeability of wood. The effects of impregnation on microwave-pretreated wood with low-molecular weight phenol formaldehyde resin was investigated.

Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]
, 2012 In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.

Determination of the diffusion of monovalent cations into wood under isothermal conditions based on LiCl impregnation of Norway spruce [PDF]
, 2013 The impregnation of wood pieces in the course of pulping can be divided into primary (advective masstransport) and secondary (diffusive mass transport) penetration.Little is known about the latter partly because of the difficulties in the determination ...

Wood impregnation of yeast lees for winemaking
Food Chemistry, 2015 This study develops a new method to produce more complex wines by means of an indirect diffusion of wood aromas from yeast cell-walls. An exogenous lyophilized biomass was macerated with an ethanol wood extract solution and subsequently dried. Different times were used for the adsorption of polyphenols and volatile compounds to the yeast cell-walls ...

Effect of Nickel Impregnation on Wood Gasification Mechanism [PDF]
Waste and Biomass Valorization, 2017 To study its catalytic effect, nickel were inserted intentionally by impregnation into the biomass. In this context, the influence of the Ni amount in the solution during wood impregnation has been analyzed in terms not only of catalytic activity and samples compositions but also on the wood structure.
