Kirjallisessa osuudessa syvennyttiin erityisesti puuhun biomassana pyrolyysissa.

Kirjallisessa osuudessa k\u00e4siteltiin my\u00f6s lopputuotteiden karakterisointi- ja analysointimenetelmi\u00e4, jotka ovat usein biomassan pyrolyyseiss\u00e4 haastavin osuus johtuen biomassan kompleksisuudesta sek\u00e4 pyrolyysist\u00e4 analyysimetodina.\n\nKokeellisen osuuden tarkoituksena oli l\u00f6yt\u00e4\u00e4 esik\u00e4sittelymenetelm\u00e4, joka suojaisi puun selluloosaosaa (erityisesti hemiselluloosaosaa) keitossa ja t\u00e4ten saataisiin parempi saanto puusta selluloosatuotannossa.
