Question

An important step in the manufacture of pulp for paper industry from the woody tissues of plants is the :

• A. Preparation of pure cellulose by removing lignin
• B. Removal of oils present in the wood by treatment with suitable chemicals
• C. Removal of water from the wood by prolonged heating at approximately 50°C
• D. Treatment of wood with chemical that breakdown cellulose

Answer 1

Answer: (A)

Preparation of pure cellulose by removing lignin

Answer 2

In the pulp and paper industry, the process of delignification is essential to remove lignin from wood and obtain pure cellulose fibers, which can be used to make high-quality paper products. Removing lignin is a critical step because lignin is a non-cellulosic component that can interfere with paper quality and strength.

So, the correct option is (A): Preparation of pure cellulose by removing lignin
