Abstract: A Feeding apparatus for a pyrolytic reactor, comprising a rotatable inclined drum, a motor for rotating the drum, a hopper by which aggregatable feedstock pieces introduced to the interior of said drum, and a feed tube extending from the drum to a pyrolytic reactor. The rotation of the drum applies forces of sufficient magnitude and varying direction to an aggregated mass of feedstock pieces that constituent feedstock pieces are separated from said aggregated mass and are discharged from the drum via the feed tube to the pyrolytic reactor.

Abstract: A process for the recovery of sulfur from the products resulting from the pyrolysis of sulfur-containing organic materials, comprises the steps of: a) carrying out the combustion of liquid pyrolysis products, thereby to obtain sulfur dioxide in the formed exhaust gases; b) reacting hydrogen sulfide recovered from gases, generated in the pyrolysis process, with said sulfur dioxide; and c) reacting hydrogen sulfide recovered from gases, generated in the gasification of solid pyrolysis products, with said sulfur dioxide, and as a result to obtain elemental sulfur, pure gaseous fuel and exhaust gases from liquid products combustion free from sulfur-containing compounds.

Abstract: The present invention is an energy efficient method for separating petroleum-based waste including sludge, bottoms or used lubricants. By using solid particles and water, and converting them into useable end products, for example gas and gas/oil fractions. The process produces no wasteful by-products like polluted sewage, heavy asphaltenics and tar by-products. Instead, the process eliminates water through selective adsorption by dewatering additives and the process is followed by drying at high temperatures. The dewatering additives are recycled from other processes and are reusable themselves. After skimming the dewatered matter, the remainder is processed by thermocatalytic cracking. Some of the active materials in the cracking reaction are again waste products of other reactions. The gas and gas oil fractions obtained from this process conform to standard specifications. The process uses equipment that is cost-effective and that are routinely produced.

Abstract: The present invention is an energy efficient method for processing petroleum-based and other organic waste including sludge or bottoms, by utilizing of heat energy of oil shale ash or of other suitable ashes obtained from burning the solid fuel. The process produces no wasteful by-products like polluted sewage, heavy asphaltenics and tar by-products. Instead, the process eliminates water through selective adsorption by the ashes used as dewatering additives and the process is followed by drying at high temperatures. After skimming the dewatered matter, the remainder is processed by thermo-catalytic cracking by using hot oil shale ash or other ashes as a catalytic active material and as a heat carrier. The process uses equipment that is cost-effective and that is routinely produced. The process and apparatus of the present invention provide a solution for processing refinery and petroleum-based wastes and producing useful and standard liquid fuels.
