چکیده

In this study, the technoeconomic feasibility of bioenergy production from sawdust under four different case scenarios is simulated and compared. These include: (1) heat electricity generation raw sawdust; (2) pellet (3) (4) integrated biorefinery approach for simultaneous manufacturing multiple products (steam-exploded torrefied pellets) co-products (furfural, hydroxy methyl furfural (HMF), acetic acid), along with generation. Economic assessments such as cost analysis, payback time (PBT), net present value (NPV) internal rate return (IRR) were determined these scenarios. The results showed that producing pellets, furfural, acid, co-generated electricity, in terms multiproducts profitability (NPV (at 7%): USD 38.29 M) was preferable over other alternatives. simplified technology economic indices (PBT: 2.49 year, IRR: 51.33%, on investment (ROI): 40.1%), scenario pellets wood more promising than others. If plant capacity not a limiting factor, optimal size combined power (CHP) between 250–300 kt main product. Additionally, untreated treated plants equipped CHP had an 150–200 per year.

Preparation, characterization and phenol adsorption capacity of activated carbons from African beech wood sawdust

In the present study, different activated carbons were prepared from carbonized African beech wood sawdust by potassium hydroxide activation. The activated carbons were characterized by brunauer–emmett–teller, scanning electron microscope, fourier transform infrared spectroscopy, and thermogravimetric analyzer. The phenol adsorption capacity of the prepared carbons was evaluated. The d...

The Possibilities of Bioenergy Production from Whey

The wastes and the by-products of food industrial technologies are suitable for bioenergy generating because of the high organic matter content. Anaerobic digestion is the eldest technology for waste stabilization and however by controlled decomposition a high value and marketable energy source can be produced. Whey is normally used as a component of dairy products or as an additive for food pr...
