The α-cellulose powder obtained from the corn cob was hydrolyzed at room temperature with 2 N hydrochloric acid under reflux for 15 min (Paralikar and Bhatawdekar 1988); the solid-liquor ratio was 1 10.
Analysis of the relative glucose present in the recovered solids, pretreatment liquor and final residual solid after saccharification process streams indicate that at all of the biomass loadings very little (<1%) glucose remained as a solid.
In all cases, corncob was first suspended in DI water with a solid to liquor ratio of 1 10 (g mL−1) and ultrasound for 30 min.
The HTP process was carried out in a 1,000-mL 1,000-mLstainlessutoclave (Parr Insteelent Compautoclavene, IL, USA) with a magnetic stirrer at a solid to liquor ratio of 1:10 (g/mL) by a Parr Instrument Company848).
Detention time, volatile solids destroyed, mixed liquor solids, digested sludge concentration and temperature in aerobic digestion are 18 days, 40%%, 12,000 mg/L, 2.5 % and 23 °C, respectively.
The forms of cocoa that we are familiar with today have these brown cocoa solids —chocolate liquor and cocoa powder which are the ingredients of chocolate candy, cakes, cookies and hot cocoa beverages.
An analysis of a process for recovery of both products of a double decomposition reaction through two consecutive evapocrystallization-washing steps is conducted on the basis of a simple expression for the heterogeneous equilibrium between the precipitated solids and liquor ions concentrations.
The washed solids and liquors were stored in a refrigerator until the liquors underwent compositional analysis or the solids underwent enzymatic hydrolysis.
Total solids (TS), volatile solids (VS), and mixed liquor suspended solids (MLSS) of the corn stover, sludge, and their mixture were measured using APHA standard methods.
Furthermore, the mixed liquor-suspended solid (MLSS) and mixed liquor volatile-suspended solids (MLVSS) concentration raised from minimal concentration to about 6.6 and 6.1 g/L, respectively.
The washing step of dilution and separation of pretreated solids from liquors is performed prior to possible downstream mechanical refining.
