摘要:
A method for producing biochar particles or pellets which use sulphur and other additives. The method includes producing a mixture with biochar and additives selected from sulphur, lignin, and gluten. The mixture is mixed with water and passed through an extruder to produce an extrudate. The extrudate is then cut into pellets. The pellets are then tumbled/spun with each other and heated to result in mostly spheroidal pellets whose mechanical characteristics allow them to be used with well-known agricultural equipment. The biochar can be produced with sulphur incorporated as an outer coating. To produce this sulphur coated biochar, the method includes feeding a biomass feedstock to a pyrolysis reactor, pyrolyzing the feedstock into biochar particles, size-sorting the biochar particles, and coating the biochar particles with the sulphur coating material.
摘要:
Mercury adsorbed from combustion gas by activated carbon can be sequestered in concrete containing air-entraining admixtures. The activated carbon may be made by providing a carbon char made from coconut shell, wood, or lignite that was activated by a method selected from the group consisting of activating with steam, activating with CO2, activating in an environment containing free oxygen, and combinations thereof to provide an activated carbon with an Acid Blue 80 Index of less than about 30 milligrams per gram of carbon. The activated carbon may be injected into a combustion gas stream containing fly ash and mercury and may then be removed with fly ash from the gas stream. The resulting composition may be used as a partial substitute for cement in air-entrained concretes.
摘要:
Solid adsorbents, following their use for mercury removal from flue gas, that do not interfere with the ability of air-entraining additives (such as surfactants) to form stable bubbles when added to fly ash containing the adsorbents. The interference is overcome by heating the materials used in the manufacture of the adsorbent so that magnesium hydroxide and/or one or more alkali compounds containing one or more silicate, aluminate, and/or phosphate moiety, added or already present in the materials, binds multivalent cations present in the materials that could otherwise interfere with the surfactant activity.

The present invention relates to a method of draining water comprising the steps of:
providing a water drainage device, wherein the water drainage device comprises man-made vitreous fibres (MMVF) bonded with a cured aqueous binder composition free of phenol and formaldehyde; positioning the water drainage device in contact with the ground, wherein the water drainage device absorbs water and releases water to a recipient
wherein the aqueous binder composition prior to curing comprises;
a component (i) in form of one or more lignosulfonate lignins having a carboxylic acid group content of 0.03 to 1.4 mmol/g, based on the dry weight of the lignosulfonate lignins, a component (ii) in form of one or more cross-linkers.
摘要:
The invention discloses a humic acid type adsorption material as well as a preparation method and application thereof. The humic acid type adsorption material is prepared by taking carboxymethyl cellulose or salts thereof, humate and montmorillonite as raw materials and adding a monomer, a cross-linking agent and an initiator through aqueous solution polymerization. The synthesized porous material is great in specific surface area, can quickly get close to water molecules in water to form hydrogen bonds, and finally achieves the purpose of removing organic dye pollutants through electrostatic attraction effect with dye molecules. The humic acid type adsorption material is low in raw material price, is simple in synthesis process, and is green and environmentally friendly.
