Enzymatic pretreatment of steam-exploded birch wood for increased biogas production and lignin degradation
Hashemi, Seyedbehnam; Joseph, Prajin; Mialon, Antoine; Moe, Størker T.; Lamb, Jacob Joseph; Lien, Kristian Myklebust (Peer reviewed; Journal article, 2021)Lignocellulose is readily available biomass for biogas production; however, due to its rigid structure, it requires pretreatment to obtain a maximum energy extraction. In this study, steam explosion (SE) (220 °C and 10 ... -
INJECTION OF SYNTHETIC PRODUCED WATER INTO POROUS MEDIA - A study of transport of dispersed components through simulated reservoir packs
Joseph, Prajin (Master thesis, 2018)Produced water(PW) contributes to the largest volume byproduct from the oil production industry. The presence of hazardous chemicals makes the handling of PW an important and costly operation. Methods such as discharge ... -
Morphology of lignin structures on fiber surfaces after organosolv pretreatment
Joseph, Prajin; Ottesen, Vegar; Tanase-Opedal, Mihaela; Moe, Størker T. (Peer reviewed; Journal article, 2022)The redeposition of lignin to the fiber surface after organosolv pretreatment was studied using two different reactor types. Results from the conventional autoclave reactor suggest that redeposition occurs during the cooling ... -
The O-factor: using the H-factor concept to predict the outcome of organosolv pretreatment
Joseph, Prajin; Opedal, Mihaela Tanase; Moe, Størker (Peer reviewed; Journal article, 2021)The H-factor, a parameter used extensively to analyze and predict the outcome of kraft pulping, is applied to organosolv pretreatment. The total solid yield after organosolv pretreatment fits well with the H-factor. The ... -
Organosolv pretreatment of Norway spruce: Ethanol pretreatment for Biorefinery applications
Joseph, Prajin (Doctoral theses at NTNU;2022:385, Doctoral thesis, 2022)The acceleration of climate change and the depletion of oil reserves forced the society to look for alternative fuel sources. Among the available alternatives, second generation biofuel is gaining attention due to several ... -
Polymer properties of softwood organosolv lignins produced in two different reactor systems
Joseph, Prajin; Tanase-Opedal, Mihaela; Moe, Størker T. (Peer reviewed; Journal article, 2023)Lignin, the second most abundant biopolymer on earth and with a predominantly aromatic structure, has the potential to be a raw material for valuable chemicals and other bio-based chemicals. In industry, lignin is underutilized ...
