KRAFT AND MODIFIED KRAFT PULPING OF BAMBOO (PHYLLOSTACHYS BAMBUSOIDES)

Drewno. Prace Naukowe, Doniesienia, Komunikaty = Wood. Research Papers, Reports, Announcements, 2017
Delignification of bamboo (Phyllostachys bambusoides) grown in the Eastern Black Sea region of Turkey was carried out by kraft, kraft-anthraquinone (AQ) and kraft-sodium borohydride (NaBH4) pulping under a variety of conditions to determine the effect of AQ, NaBH4 and cooking parameters on pulp and paper properties such as yield, kappa number ...

Revisiting acidulation for tall oil and lignin manufacturing

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Tall oil is a byproduct of the kraft pulping process when softwood is used as raw material. As the production of softwood‐based pulp is in high demand, the optimization of the tall oil production process needs to be revisited to ensure the highest quality and quantity of tall oil manufacturing. In this work, the process for tall oil production

Nitric Acid-Alkali Two-stage Pulping of Wheat Straw, Industrial Hemp, and Miscanthus x giganteus

BioResources, 2023
Index levels of the process of pulping wheat straw (WS), industrial hemp stalks (HS), and Miscanthus x giganteus (MS) using the nitric acid-alkali (NA-A) method (HNO3/KOH and HNO3/NH4OH two-stage sequential delignification systems) were determined.

The Effects of Fiber Furnish on Physical Properties of Paper [PDF]

, 1975
This experiment was designed to determine the effects of fiber furnish on the physical properties of paper. To do this various pulps and combinations of these pulps were formed into handsheets and their physical properties determined. The tests performed

Board That Transforms: Relationship Between Board Structure and Environmental, Social, and Governance Performance in BRICS Countries

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT The purpose of this study is to examine the relationship between board composition characteristics and ESG performance in companies from BRICS countries, and to assess how sector sensitivity moderates this relationship. A sample of 2045 BRICS companies was examined using panel data regression with random effects and logistic regression ...

Copper‐Based Conductive Nanoinks: Scalable Synthesis via Continuous‐Flow Microwave‐Assisted Polyol Process

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Microwave‐assisted polyol synthesis in continuous flow produces metallic Cu nanoparticles, using ethylene glycol as solvent and reducing agent, lignin to stabilize the colloid and prevent oxidation, and metal‐seeds for particle size control. Metallic copper nanoparticles are a promising alternative to gold and silver in printed electronics due to their

Sulfuric acid bleaching of kraft pulp 1: Bleaching of hardwood and softwood kraft pulps

Journal of Wood Science, 1999
To develop a new nonchlorine bleaching technology, hardwood and softwood kraft pulps, before and after oxygen-alkali predelignification, were treated with dilute sulfuric acid solutions (pH 1.0-1.8) at 100°C for 1 h and then extracted with aqueous sodium hydroxide at 70°C for l h. Hardwood kraft pulp was successfully bleached.
