Temperatures and pressures listed in Table 1 are measured values, and variances between samples are due to changes in feedstock, sweep gas, and downstream equipment selection.
The advantages of multitubular over adiabatic reactors are also discussed in terms of flexibility with respect to changes in feedstock composition and flowrate.
The model is flexible in that it can be modified to calculate the effects on capital and production costs of changes in feedstock cost, changes in the type of feedstock employed, changes in the value of the glycerol coproduct, and changes in process chemistry and technology.
The authors list uncertainties in residence time calibration and changes in feedstock acid neutralizing capacity as possible factors [ 26].
Differences between the granular and liquid biomass fractions of each sample were less pronounced than differences attributable to the change in feedstock, however the results suggest that there are different functional groups in each fraction.
Reducing lignin biosynthesis can lead to lower recalcitrance and higher saccharification efficiency, making lignin composition and amount an obvious target to change in lignocellulosic feedstocks [ 6].
The future of food could see unemployment issues in farming; large changes in livestock and feedstock production; and significant alterations in land management.
Recent changes in the availability of feedstocks, including renewables and tight oils, and longer-term trends in the demand for propylene, gasoline, and middle distillates require further developments in both catalyst and process.
The sensitivity of the MBSP to changes in the prices of feedstock and of products has been examined by changing one price at a time from -50% to +50%.
Due to the fact that wastewater flow rates as well as the levels of contaminants may vary widely as a result of changes in operational conditions and/or feedstock and product specifications, optimal wastewater network designs should be resilient and able to accommodate such changes.
