Different technological alternatives for the thermochemical production of liquid fuels from lignocellulosic biomass are systematically analyzed and optimized based on thermo-environomic models. The competitiveness of the production of Fischer-Tropsch fuel ...
A detailed thermo-economic model considering different technological alternatives for thermochemical production of Synthetic Natural Gas (SNG) from lignocellulosic biomass is presented. First, candidate technology for processes based on biomass gasificatio ...
We calculated carbon and energy flows in 11 models of FT plants. While uncertainties are substantial, our best- guess estimates indicate that FT diesel is economically competitive, with fuel costs comparable to fossil diesel derived from oil at 34 $/bbl fo ...
This paper investigates different design strategies and process layouts for upgrading crude synthetic natural gas (SNG) produced from lignocellulosic biomass to grid quality. The design problem is outlined by studying the involved key aspects with respect ...
Ultrasound propagates through an elastic medium at a rate or speed named the ultrasound propagation velocity (UPV). This velocity is detd. by the rate at which the wave energy is transmitted, inversely related to the square root of the d. and compressibili ...
Current and future dynamics, of environmental legislations and trading market, of the fuel and electricity prices due to the market liberalization or resource shortages, and of the innovations of power/cogeneration technologies, impose great challenges on ...
Inline conversion measurements in chem. reactions are in general and esp. in polymn. reactions necessary for process monitoring and control. For polymn. monitoring, the sound propagation (UPV) can be related to the texture of the bulk with a high accuracy. ...
A study comparing several technical options for producing Fischer-Tropsch fuel by biomass gasification has been performed. Each step of the process has been simulated using ProsimPlus, a process simulation software: gasification, gas cleaning, FT synthesis ...
The catalytic influence of major metal species found with waste wood (Na, K, Ca, Mg, Zn, Pb, Cu) was studied during the gasification of nitrate salt impregnated charcoal with CO2 at 800degreesC in the kinetically controlled regime. In contrast with literat ...
Tubular recycle reactors for polymn. are characterized by their macroscopic and microscopic mixing efficiency. Static mixers show a nearly plug-flow behavior over a wide range of viscosities (10-3 - 103 Pa s). The high heat transfer capacity of the reactor ...
