1. A fractionation process for producing value-added bioproducts from a lignocellulosic biomass, comprising:
- a) mechanically refining the lignocellulosic biomass under mild refining conditions to form a refined biomass pulp with enhanced susceptibility to separation of hemicellulose, cellulose and lignin, and enhanced digestibility of carbohydrates in hydrolysis b) separating hemicellulose and sulfur-free high-quality lignin from cellulose in the refined biomass, and, optionally c) producing various bioproducts from the above said process.

9. A fractionation process for producing value-added products from a lignocellulosic biomass, comprising:
- i) mechanically refining the lignocellulosic biomass under mild refining conditions to form a refined biomass pulp, ii) extracting a hemicellulose fraction from the refined biomass pulp to leave a residual pulp containing lignin, iii) hydrolysing carbohydrates in the residual pulp to sugars, iv) separating a lignin fraction from the sugars, iv) fermenting said sugars to form biofuels, and v) recovering the hemicellulose fraction and the sugar alcohol as value-added products.
