Lignocellulose Biorefinery – pulping of lignocellulosic raw materials and complete material utilisation of all components (LCB II);Subproject 2: Pilot plant, pulping, component separation and lignin utilisation
Project
Project code: TI-HF-08-PID1632
Contract period: 01.05.2010
- 30.09.2013
Budget: 385,505 Euro
Purpose of research: Applied research
The planning and construction of a pilot plant for Organosolv pulping was supported. In addition extensive investigations for the material use of lignin were performed (lignin-phenol resins, polyurethans, aromatic platform chemicals
In the subproject three different topics were covered. Besides the pulping process the utilisation of lignin under maintenance of the polymeric structure and after thermochemical degradation was pursued. For pulping the reaction conditions were adapted to a large digester in Hamburg (30L) in order to provide data for the planning and construction of the Leuna pilot plant. In addition these experiments provided material for the work of the various partners. In addition analytical support was provided for the start-up operation of the pilot plant. Lignin utilisation under maintenance of the polymeric structure was focused on the production of lignin phenol formaldehyde resins and urethane foams and films. This included the development of new derivatisation and modification roots. The thermochemical conversion was targeted on a high yield of aromatic compounds as lignin derived platform chemicals.
Organosolv pulping was optimized in 30 L scale and complete balances were developed for the total process including enzymatic hydrolysis. This included concepts for the refinement of various product streams. Synthesis of lignin phenol formaldehyde resins was investigated for various lignin qualities and modification reactions in laboratory scale and samples were evaluated by testing veneer glue joints. Selected products were scaled up and tested in wood products. For lignin based urethanes new synthesis concepts were developed in lab scale and tested in small test specimen for foams and films. For thermochemical reactions various catalyst and reaction liquids were investigated.
