A system for forming a woody biomass component and a binder component into a solid fuel element having a predetermined density. The system includes a first compression assembly for compressing an uncompressed mixture of the woody biomass component and the binder component to provide a first compressed mixture formed into a preliminary element having a preliminary density. The system also includes a second compression assembly for compressing the preliminary element to form the solid fuel element having the predetermined density, which is greater than the preliminary density.

The invention relates to inorganic and polymeric reagents and namely to pipeline transfer of petroleum and petroleum products. The method of production of a reagent for reduction of hydrodynamic resistance of liquid hydrocarbon flow in pipelines includes polymerization of C6-C14 alpha-olefins over catalyst and catalyst activator. Polymerization of C6-C14 alpha-olefins is conducted in the monomer medium with addition from 0.1 to 5 w/w of a saturated alicyclic hydrocarbon of C8-C32 composition and a saturated aliphatic hydrocarbon of C6-C18 composition subject to conversion of monomers from 96.0 to 99.5 w/w, using microspheric titanium trichloride as a catalyst, and a mixture of diethylaluminum chloride and triisobutylaluminum with weight ratio from 1:10 to 10:1 as a catalyst activator. Then a polymer with molecular weight more than 10.sup.7 atomic mass unit with narrow molecular weight distribution not more than 1.5 with the set ratio of components is produced. Then the polymer is being ground.

A process of making a fuel product from a non-combustible high protein organic material such as a biological by-product or waste material. The moisture content of the high protein organic material is mechanically reduced and dried to reduce the moisture content to less than ten percent (10%). The high protein organic material is pulverized to a particle size of less than about 2 mm. The high protein organic waste material is fed into a combustion chamber and separated during combustion such as by spraying high protein organic waste material within the combustion chamber. Temperature and combustion reactions within the combustion chamber are controlled by controlling the moisture in the combustion atmosphere and energy injections at or downstream of the combustion chamber. The concentration of protein thermal decomposition by-products, temperature, and residence time and/or additions of energy plasma within the combustion chamber environment are controlled to degrade hazardous polyfluoro compounds.

Provided is a method of preparing a combustible oil, the method comprising adding and mixing: a petroleum-based combustible oil; a water having an oxidation-reduction potential of 300 mV or lower, a pH of 9.0 or higher, and a dissolved hydrogen concentration of 0.8 ppm or higher; a fatty oil; and an activated carbon to obtain a mixture.

Methods, apparatuses, and systems to collect fine particle coal are provided herein. For example, these methods, apparatuses, and systems may be incorporated into a coal processing plant to collect a portion of the fine particle coal that is normally lost in the system. A fine particle coal also is provided. The fine particle coal may have a particle size of 1000 m or smaller and a water content of from about 5% to about 20%, by weight.

A method for enhancing the efficiency of a liquid fuel is described. The method involves the addition of cobalt hydroxystannate nanoparticles to the liquid fuel to produce an enhanced liquid fuel. The cobalt hydroxystannate nanoparticles may be present at a concentration of 50-200 ppm, and may increase the calorific value of the fuel by a factor of 25-52 times.

A multifunctional comprehensive mineral supplement including molecular clusters, wherein at least a portion of the molecular clusters each has a metal core and one or more ligands attached to the metal core, wherein at least a portion of the metal core and/or one or more ligands is provided by or derived from a mineral component.

Coal fines are processed by flotation separation to separate coal particles from ash-forming mineral content particles. Coal fines are mixed water under high shear mixing conditions to form an aqueous slurry of coal fines containing between 15 wt. % and 55 wt. % coal fines. The aqueous slurry is introduced into a coal flotation cell to separate coal particles from ash-forming mineral content particles by flotation separation, wherein the coal fines have a particle size less than 100 m, and more preferably less than 50 m. Bubbles are generated in the coal flotation cell having a bubble size and bubble quantity selected to float the coal particles and to form a coal-froth containing at least 15 wt. % solid particles. The solid particles include coal particles and ash-forming mineral content particles. The coal-froth is collected for further processing.

A fuel additive composition has a base fuel; colloidal nanocarbon particles, and a dispersion stabilizer that aids in stably suspending the colloidal nanocarbon particles in the base fuel. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this abstract.
