PRIMARY IDENTIFICATION OF EUCALYPTUS (Eucalyptus camaldulensis) WOOD LIGNIN MONOMERS BY FT-IR SPECTROSCOPY [PDF]
Lignin samples were isolated from Eucalypt wood (Eucalyptus camaldulensis) by kraft process, and then all samples were examined and tested with Fourier Transform Infrared Instrument Technique for identifying the types of lignin monomers units from their ...

Process for purification of waste water produced by a Kraft process pulp and paper mill [PDF]
The water from paper and pulp wastes obtained from a mill using the Kraft process is purified by precipitating lignins and lignin derivatives from the waste stream with quaternary ammonium compounds, removing other impurities by activated carbon produced

Associations of Sleep and Shift Work with Osteoarthritis Risk
Objective Daily rhythms may be critical for maintaining homeostasis of joint tissues. We aimed to investigate the relationships between circadian clock disruption, sleep, and osteoarthritis (OA) risk in humans. Methods In the UK Biobank, a prospective 500,000‐person cohort, we evaluated associations between sleep duration, sleeplessness/insomnia, and ...

PACTTM process for treatment of kraft mill effluent
The PACTTM process (powdered activated carbon addition to the activated sludge process) was evaluated for the treatment of Kraft pulp mill wastewater in a series of bench scale experiments. Possibly due to the relatively low strength wastewater, the PACTTM process with carbon doses between 0.5 and 1.0 g/L of influent only performed marginally better ...

Simulation of a biorefinery process as learning tool in chemical engineering degree [PDF]
Currently, the search for alternative biomass to be used as renewable sources for energy production is one of the most important challenges to achieve a sustainable growth based on a bioeconomy strategy (Mendes et al., 2009).

Influence of the Chemical Properties of Wood on the Odor Produced by the Kraft Pulping Process
Chemical reactions occur between inorganic compounds and wood chips during the cooking step of the Kraft process. White liquor, which in this process is composed of sodium hydroxide (NaOH) and sodium sulfide (Na2S), is mixed with wood chips in the ...
