Subcritical Water Process for Reducing Sugar Production from Biomass: Optimization and Kinetics

Pretreatment optimization methods for increased sugar yields from biomass pyrolysis

In the search for a renewable energy source that could replace petroleum and other nonrenewable energy sources, pyrolysis of biomass is a hopeful alternative and pretreatment could further improve its potential. There are several possible routes for pretreating lignocellulosic biomass, but many need further refining before becoming economical. The main obstacle for the conversion of biomass to ...

Subcritical Water Hydrolysis Treatment of Waste Biomass for Nutrient Extraction

Nutrients were extracted from corn stalks, peanut shells, de-oiled peanut meal, chicken manure, and sewage sludge by a subcritical water (SCW) hydrolysis reaction. Compared with the other feedstock, the aqueous phases extracted from de-oiled peanut meal showed the highest watersoluble organic carbon, amino acid, total nitrogen, and phosphorus contents. The effects of solution pH, final hydrothe...

Production and Management of Sugarcane Biomass — Process Optimization

Co-liquefaction of microalgae and lignocellulosic biomass in subcritical water.

This study investigated co-liquefaction of microalgae (Chlorella pyrenoidosa, CP) and lignocellulosic biomass (Rice husk, RH) in subcritical water for bio-oil production. The effects of liquefaction temperature (200-350°C), residence time (10-90min), solid concentration (10-30wt.%) and mass ratio of CP/RH on product distribution were investigated. The results showed that the highest yield of bi...

Optimization of Process Conditions for Subcritical Water Hydrolysis of Sugarcane Bagasse

Optimization of operation conditions (temperature, time, solvent: solid proportion) of subcritical water hydrolysis (SWH) is needed so that it can be considered an effective process for second generation bioethanol manufacturing. The objective of this study was to optimize operation conditions using a semi-batch SWH system equipped with a 50 mL reaction vessel. Initially, the process was carrie...
