Increased use of whole-plant maize for anaerobic digestion (AD) in Europe raises the question: Are maize cultivars developed for use in animal nutrition equally appropriate as feedstock for AD or should different phenotypes be selected? The main objective in growing whole-plant maize as feedstock for AD is maximum output of methane per hectare. There is less need for rapidly digested plant comp...

Due to the concern on the availability of recoverable fossil fuel reserves and the environmental problems caused by the use those fossil fuels, considerable attention has been given to biodiesel production as an alternative to petrodiesel. However, as the biodiesel is produced from vegetable oils and animal fats, there are concerns that biodiesel feedstock may compete with food supply in the lo...

Bioethanol is mostly produced from wheat starch in Sweden. Due to the increasing wheat price it is no longer profitable to produce bioethanol from wheat. In this paper the conditions for converting a wheat bioethanol plant to a lignocellulosic bioethanol plant are studied. The most suitable lignocellulosic feedstock is investigated and soft wood chips are chosen based on bioethanol ...

The results of a combined molecular dynamics/quantum chemistry pathology study of previously reported organic (diamondoid) tooltips for diamondoid mechanosynthesis (DMS) are presented. This study, employing the NanoHive@Home (NH@H) distributed computing project, produced 80,000 tooltip geometries used in 200,000 calculations optimized at either the RHF/3-21G or RHF/STO-3G levels of theory based...

Biochars have been proposed for remediation of metal-contaminated water due to their low cost, high surface area and high sorption capacity for metals. However, there is a lack of understanding over how feedstock material and pyrolysis conditions contribute to the metal sorption capacity of biochar. We produced biochars from 10 different organic materials by pyrolysing at 450 °C and a further 1...

Developing biomass-based power generation is helpful for China to reduce the dependence on fossil fuels and to release the targets of carbon emission peak. The decentralized farming method leads to Chinese farmers’ weak willingness to collect and sell crop residues to biomass-based power plants. The purpose of this paper is to solve the issue by proposing a novel biomass feedstock supply model ...

Feedstock conversion and yield products are studied through a 3Dmodel simulating the main reactor of the fluid catalytic cracking (FCC) process. Computational fluid dynamic (CFD) is used with Eulerian-Eulerian approach to predict the fluid catalytic cracking behavior. The model considers 12 lumps with catalyst deactivation by coke and poisoning by alkaline nitrides and polycyclic aromatic adsor...

Removing excess biomass from fire-hazardous forests can serve dual purposes: enhancing the health and sustainability of forest ecosystems and supplying feedstock for energy production. Considerable efforts have been made to estimate the quantity of this biomass available on the ground, yet availability does not necessarily translate into actual supply. This seems especially evident for nonindus...

Al2O3 ceramic reinforced with 4-wt% multiwalled carbon nanotube (CNT) is plasma sprayed for improving the fracture toughness of the nanocomposite coating. Two different methodologies of CNT addition have been adopted in the powder feedstock to assist CNT dispersion in the nano-Al2O3 matrix. First, spray-dried nano-Al2O3 agglomerates are blended with 4 wt% CNT as powder-feedstock, which is subse...

Here we report the 3.7-Mb draft genome sequence of Acetobacter tropicalis NBRC16470(T), which can produce optically pure d-glyceric acid (d-GA; 99% enantiomeric excess) from raw glycerol feedstock derived from biodiesel fuel production processes.
