  • Patent number: 10465121
    Abstract: A method of processing a carbonaceous material in the form of carbonaceous fines is provided in which the carbonaceous material is treated with micro-algae to adsorb the micro-algae onto the carbonaceous material followed by heating in a heat activating step. Such heating is effected to a temperature within the range of from that at which water starts evaporating to a temperature at which volatile components of the carbonaceous material start to volatilize. The heating is continued for a duration selected to allow chemical interaction between the micro-algae and the carbonaceous material so as to alter the chemical structure of the carbonaceous material. The carbonaceous material microalgae are preferably in the form of substantially intact cells that are still in a photosynthetically active state. Dry carbonaceous materials may be mixed with micro-algae slurry in water, or micro-algae may be added to carbonaceous material already present in water.

  • Publication number: 20160002553
    Abstract: A method is provided for the treatment of water containing micro-algae wherein the water is contacted with carbonaceous fines to adsorb micro-algae onto particles of the carbonaceous fines. The carbonaceous fines may be coal or charcoal fines or mixtures thereof. The carbonaceous fines may be pre-treated to remove any unsuitable or valuable materials therefrom; or to produce suitable size ranges of particles for one or more purposes selected from facilitating adsorption; handling of the carbonaceous fines both before and after adsorption of the micro-algae; and separation of the carbonaceous fines with adsorbed micro-algae thereon. The method may target the beneficiation of carbonaceous fines and the carbonaceous fines together with the adsorbed microalgae thereon may be subjected to an agglomeration process for the production of agglomerates such as briquettes or pellets. The method may target the upgrading of a polluted water system in a commercial water treatment process.

  • Publication number: 20110198389
    Abstract: This invention relates to a friction welding apparatus, and more particularly, but not exclusively, to a modular friction welding apparatus suitable for in-situ reparation of blind holes in pipes. The friction welding apparatus includes a frame assembly, a spindle assembly for holding a friction welding consumable; and a drive assembly for driving a spindle of the spindle assembly. The spindle assembly and the drive assembly are releasably securable to the frame assembly so as to form a modular friction welding apparatus, and the frame assembly is furthermore removable securable to an object to be welded.

  • Publication number: 20100305332
    Abstract: The present invention relates to a method for the preparation of a functionalized nano size transition metal oxide or sulfide particle comprising the steps of (a) providing a ternary solvent system comprising a polar solvent, a non-polar solvent and an intermediate solvent allowing miscibility of all three components; (b) providing a mixture of a transition metal salt and a ternary solvent; (c) providing a mixture of a suitable source of oxide or sulfide and the ternary solvent; (d) providing a mixture of a non-polar end capping agent and the non-polar solvent; (e) mixing the mixtures; and (f) recovering the resultant functionalized nano size transition metal oxide or sulfide particle. The invention further relates to non-polar end capped nano sized transition metal oxide or sulfide particle so produced and the use of such particles.
