Co-gasification of thermally pretreated wheat straw with Shengli lignite for hydrogen production

Advances in Pretreatment of Straw Biomass for Sugar Production

“…In the imidazole ionic liquid system containing 20% water, lignin removal and glucose digestibility can be increased by decreasing the pH of the solution . EMIMAc containing NaOH was used to pretreat corn stalk, giving 85.69% hemicellulose, 9.1% cellulose, and 87.4% lignin removal under the best conditions of the liquid-solid proportion of 8.7:1 at 98.5°C for 1.31 h (Liu et al, 2018).…”

“…For example, rice straw was pretreated by wet and dry milling, under the treatment conditions such as the particle size of 0.5 mm and ball speed of 350 rpm/min ground for 30 min (Kumar and Sharma, 2017). Chipping could decrease the size of straw to 10-30 mm, while grinding could decrease to 0.2 mm, which exhibited the best enzymatic efficiency and highest yield of sugars (Kumar and Sharma, 2017;Liu et al, 2018).…”

“…However, the major shortcomings of the LHW process require a rigorous reactor configuration ( Oliveira et al, 2014 ; Capolupo and Faraco, 2016 ; Wang et al, 2018 ). Besides, it would consume a large amount of energy in downstream processing because plenty of water is included ( Rajput and Zeshan Visvanathan, 2018 ; Shahabazuddin et al, 2018 ; Yang et al, 2018 ).…”

Experimental Study on Chemical Looping Co-gasification of Alfalfa and Polyethylene with Iron Ore as the Oxygen Carrier for High H2/CO Production

“…The tar and char yields in the product distribution were found to be greatly reduced when the PE percentage of the mixture was greater than 50 wt %. Yang et al 25 used thermogravimetric analysis to evaluate the co-gasification of wheat straw and Shengli lignite in a fixed-bed gasifier. The results from both experimental apparatuses revealed that the best pyrolysis temperature for WS was around 400 °C for hydrogen gas production via co-gasification with SL.…”
