The basis of most residual fuels are atmospheric and vacuum tower bottoms, essentially residues with a "drop" of diluent such as gasoil or slurry, forming a highly unstable colloidal mixture. All crude petroleum residues contain asphaltenes, so you cannot avoid them unless you switch to marine gasoil, an uneconomic alternative.
Coal-water slurry fuel, a byproduct of coal mining, is made from water and fine coal particles; it's useful for powering diesel engines and heating power stations and gas turbines. But how is slurry created, what devices are used to do it, and why does your business or facility need a slurry system in place?

Direct liquefaction (particularly hydrothermal processing) occurs in a non-oxidative atmosphere, where biomass is fed into a unit as an aqueous slurry at lower temperatures, and bio-crude in …
The slurry oil can be blended with residual fuel oil or further processed in the coker. Carbon is deposited on the catalyst during the cracking process. This carbon, known as catalyst coke, adheres to the catalyst, reducing its ability to crack the oil.
Tank Abandonment In-place By Slurry. The Code of Federal Regulations (40 CFR 280.71) require all Underground Storage Tanks (UST) to be removed or abandoned in place by slurry .RDO has been providing these services to our customers for over 20 years. NDEP – UST Permanent Closure Requirements & Guidelines
Biomass Energy. The dead parts of plants and trees, and the waste material of animals are called biomass. Biomass is the organic matter which is used as a fuel to produce energy. Biomass includes wood, agricultural wastes (crop residues) and cow-dung. Biomass is another form in which solar energy manifests itself.
Slurry manure is typically between 5% and 15% solids. It is "thicker" than liquid manure, but cannot be stacked or handled the same way as solid manure. Some common system for handling and storage of slurry manure are described in this article. Collecting Slurry Manure.
The liquid hydrocarbons employed to make the slurry fuels will be conventional jet fuel types such as methylcyclohexane, JP-4, JP-5, JP-9, JP-10, RJ-4, RJ-5, RJ-6 and the like or their mixtures. The technology for making slurry fuels from these materials is well known and will be employed in making the fuels of this invention.
Biogas refers to a mixture of gases produced by the anaerobic decomposition of organic matter such as agricultural waste, municipal waste, plant residue, food waste etc. Biogas consists of methane, carbon dioxide along with the small amount of hydrogen sulphide, and moisture.
The Fischer-Tropsch (FT) process, originally developed by Franz Fischer and Hans Tropsch in early 1920s, is a series of chemical reactions that involve the conversion of hydrogen and carbon monoxide into liquid hydrocarbons by using a catalyst. This process is a key component of gas to liquid technology. It produces synthetic lubrication oil ...
Cooking and Liquefaction. Once the corn slurry (mash) is made, it goes through cooking and liquefaction. The cooking stage is also called gelatinization.Water interacts with the starch granules in the corn when the temperature is >60°C and forms a viscous suspension.
A fence-protected slurry pit. A slurry pit, also known as a farm slurry pit, slurry tank, slurry lagoon or slurry store, is a hole, dam, or circular concrete structure where farmers gather all their animal waste together with other unusable organic matter, such as hay and water run off from washing down dairies, stables, and barns, in order to convert it over a lengthy period of time into ...
Slurry reactors are most frequently used when a liquid reactant must be contacted with a solid catalyst, and when a reaction has a high heat of reaction. They may be used in such applications as hydrogenation, oxidation, hydroformation, and ethynylation. The reactor shown below is a slurry phase hydrogenation reactor.
Some farmers may not have the option or desire to grow energy crops in order to boost bio-gas output to improve the economics of using AD with CHP, for what is primarily their slurry treatment system, especially if the cost of bought in feed increases in line with fossil fuel costs, putting further pressure on farmers to grow their own crops to ...
Types of Biomass Fuels. Biomass fuels are organic materials produced in a renewable manner. Two categories of biomass fuels, woody fuels and animal wastes, comprise the vast majority of available biomass fuels. Municipal solid waste (MSW) is also a source of biomass fuel. Biomass fuels have low energy densities compared to fossil fuels.
