The viability of converting wood chips and plastic to power via compact integrated catalytic fast/slow pyrolysis, combustor, and Stirling engine technologies was determined using modeling analysis. Aspen simulations followed by sizing analysis were performed to determine the size, weight, and net energy efficiency of upgrading wood chips and plastic to power using a compact energy system with a feedstock processing capacity of 1 kg h −1 . The equipment and tooling to fabricate individual components of a compact energy system were identified. The total costs of fabricating all the individual components of compact energy systems were assessed. A discounted cash flow analysis with an internal rate of return of 20% was used to assess the minimum selling price of compact energy systems. The specific energy (Wh kg −1 ) of the compact catalytic fast pyrolysis system, compact slow pyrolysis system, and compact plastic conversion system were assessed at 20, 29, and 63, respectively. The assessed capital and annual costs of manufacturing 10

“…As a result, the carbonaceous residue discharged from the gasifier (char) is only made up of carbon and ash [38]. • Estimating the yield of tar is a challenge through a thermodynamic equilibrium model, because tar is typically a non-equilibrium product [39,44]. Tar production rate depends on reaction temperature, relative amount of oxygen and catalyst, if used [45].…”

This research work proposes an integrated gasification plant for simultaneous generation of renewable electricity and drying of olive pomace, a thick sludge with a moisture content close to 60–70% (wet basis), which constitutes by far the most abundant by-product in the Spanish olive oil industry. Due to its massive rate of production and increasing associated transportation costs, olive pomace management currently represents a substantial expense for oil mills. The integrated gasification plant, which can be installed directly at oil mills, consists of a pelletizer, a downdraft gasifier under autothermal operation fueled with dried olive pomace pellets, a producer gas cooling and cleaning unit and a microturbine as power generation unit. The wet olive pomace continuously produced in oil mills is eventually dried in a co-current flow rotary drum dryer with the hot exhaust gases leaving the microturbine at temperatures close to 300 °C, allowing a self-sufficient operation of the integrated gasification plant. The integrated gasification plant was modeled using Aspen Plus® process simulator. The developed model was validated against experimental and simulation results of relevant works. Under optimum operating conditions, the electrical efficiency of the proposed plant is 18.8%, while the additional drying stage allows achieving an overall efficiency of 51.0%. Electricity consumption by the pelletizer and ancillary equipment represents 10–20% of the net electric power generation from the microturbine. However, since the integrated gasification plant is fueled with an inexpensive by-product of olive oil production that is massively produced on-site, the plant performance parameters are remarkably satisfactory.

Computational investigation of metal organic frameworks as potential drug carriers for antihypertensive amlodipine

et al. 2021

Metal organic frameworks (MOFs) have been recognized as promising materials for biomedical applications such as drug storage and drug delivery. In this study, grand canonical Monte Carlo simulations were carried out to investigate the adsorption of an antihypertensive drug amlodipine in 28 different MOFs. Among them, 19 MOFs, which were identified to outperform those traditional materials, were screened to perform molecular dynamic (MD) simulations in order to select promising candidates for drug carriers of amlodipine, and then five representative MOFs were explored further to elucidate the mechanism of amlodipine adsorption. This is the first study to investigate the correlations between self-diffusion coefficients of drug molecule and its adsorption heat, pore volumes, and largest cavity diameters of MOF-74 series. This work provides valuable insights in drug adsorption and diffusion mechanisms in MOFs at the molecular level enabling us to speed up the MD screening of suitable drug carriers prior to experiments.
