The manufacture of water-insoluble lignin-agglomerates from black liquor

Stages of manufacture can be streamlined and made much more favorable

This invention is a process for manufacturing water-insoluble lignin-agglomerates in the form of granulates or briquettes from liquor left over as waste from processes of cellulose-extraction. The extract can be used energetically or materially. The extract is firstly granulated through spray-granulation or mix-agglomeration, leaving lignin-agglomerates, then is treated with acid, lowering its pH-value and making it insoluble in water. This process can make not only lignin-granulates but also lignin-briquettes. The granulates are brought into a formative template and immersed in sulfuric acid.
