Description

Technical Field

[0001] The present invention relates to the field of biomass energy utilization, and in particular to a device and method for separating non-sulfonated carbon black from biomass. Background Art

[0002] Biomass is the fourth largest energy source after coal, oil and natural gas. It has the advantages of being clean, renewable, widely distributed and having "net zero emissions" of carbon dioxide. However, it also has the problems of low energy density, high transportation cost and imperfect utilization equipment (technology). In fact, in the process of utilizing biomass, its characteristics must be analyzed first so that the subsequent treatment process can be designed more targeted. At present, the properties of biomass are measured qualitatively and quantitatively by elemental analysis and industrial analysis in engineering, which can basically meet the analysis needs of biomass in the process of thermochemical conversion. In general, biomass raw materials have low carbon content, high oxygen content, less ash and fixed carbon, and more volatile matter. Compared with coal, biomass has lower ignition point, ash content, sulfur content and calorific value, and higher carbon, oxygen and volatile matter content. Therefore, it is a promising process to use lignin in biomass separation reaction to produce carbon black.

[0003] Lignin is considered the second largest renewable raw material after cellulose. It usually accounts for at least 20% of the biomass, although this amount varies greatly in different green plant species and different parts of the plant. Lignin exists in plants as a polymer and aggregates with the biopolymers hemicellulose and cellulose. Lignin is the only one of the three biopolymers that contains aromatic groups. Most current processes separate lignin from cellulose and then use it in papermaking. In this process, lignin is sulfonated to increase its solubility. Most of the separated lignin is burned as process energy and to recover sulfur. But the presence of sulfur on the lignin polymer reduces other uses of lignin. Summary of the invention
