Production of Feedstock Chemicals
Science, 1983Renewable raw materials may be converted by biological means to feedstocks for the chemical industry. Glucose from cornstarch is the current choice as a substrate, although advances may enable the use of less expensive lignocellulosic materials. The production of oxychemicals and their derivatives from renewable resources could amount to about 100 ...

Feedstocks for Lignocellulosic Biofuels
Science, 2010In 2008, the world produced approximately 87 gigaliters of liquid biofuels, which is roughly equal to the volume of liquid fuel consumed by Germany that year. Essentially, all of this biofuel was produced from crops developed for food production, raising concerns about the net energy and greenhouse gas effects and potential competition between use of ...

Feedstock selection for polymer and chemical production: feedstock-specific recalcitrance
Faraday Discussions, 2017Plant cell wall materials derived from a range of waste biomass sources have great potential as a source of sustainable alternatives to petrochemicals. Perhaps the most straightforward way of realising this potential would be to hydrolyse the most efficiently fermentable polymers into their constituent sugars and use yeast to ferment these into useful ...

Pretreatment of Lignocellulosic Feedstocks
2017With the aim of reducing greenhouse gas (GHG) emissions and with our dependence on non-renewable fossil fuels, lignocellulose has been proposed to be an alternative sugar-rich raw material for renewable biofuel production, especially for the transportation sector.

Advanced feedstocks for advanced biofuels: transforming biomass to feedstocks
Biofuels, 2013Biomass, with its energy-rich stores of fixed carbon and volatiles, is estimated to have a worldwide bioenergy potential ranging from nearly 10% to more than 60% of primary energy consumption [1].

AbstractThe rapid growth in the scale of rolling mill operations made possible since World War II by the introduction of Direct Chill (DC) casting is described. The corresponding development of liquid metal preparation and casting practices to provide the large piece weights requiredfor the present high-powered strip mills are outlined.

Natural gas is a very cheap and abundant raw material but its main components, methane, ethane and propane, are rather chemically inactive compounds, which makes their upgrading to more valuable products quite difficult. Moreover the natural resources are often quite far from consumers, which makes their commercialisation even more difficult.

AbstractProduction of the feedstock for steel rolling mills is shown to be a complex procedure. The problems associated with both ingot production and continuous casting are discussed and the two are compared from different aspects, e.g. quality, yield, etc.
