  • Patent number: 5853548
    Abstract: A thermolysis process for the production of volatiles for an external combustor or liquefaction of biomass solids in which specific and previously unrecognized conditions are employed. The thermolysis is carried out in a single fluidized bed of inert material operating at near atmospheric pressure, relatively low temperature, long solids and gas residence times and moderate heating rates. The distribution of the thermolysis products among, solid (char) and gases under these conditions is unique. The product effluent can be either quenched to produce a high liquid yield in addition to a low char yield or the volatile effluent can be used in either the same combustor or a second combustor to produce heat energy a particularly high efficiency system. In using a quencher, the quenched liquid is of similar composition to those obtained by so called fast pyrolysis processes of the prior art. The specified conditions are such as to allow production of liquids in high yields in an energy efficient manner.

The thermolysis is carried out in a single fluidized bed of inert material operating at near atmospheric pressure, relatively low temperature, long solids and gas residence times and moderate heating rates. The distribution of the thermolysis products among liquid (bio-oil), solid (char) and gases under these conditions is unique. In particular, contrary to the prior art, both high liquid and low char yields are obtained. Furthermore the liquid is of similar composition to those obtained by so called fast pyrolysis processes of the prior art. The specified conditions are such as to allow production of liquids in high yields in an energy efficient manner. The low severity of the conditions in comparison with previous approaches allows simplified process design and scaleup leading to lower capital and operating costs as well as easier control.

  • Patent number: 5435890
    Abstract: A preferred embodiment of the apparatus 10 for recycling used automobile rubber tires is described in which small pieces of rubber tires are progressively fed into a vertical reactor 14 of the counter-flow type in which the material progressively descends downward through the reactor 14 with process gases passing upward through the downwardly descending material to decompose and volatilize the rubber material. Oxygen-bearing gas is injected into the reactor to burn a portion of the rubber carbon to generate hot combustion gases that ascend upwardly to pyrolitically decompose the rubber pieces, and to volatilize such material. The amount of oxygen is controlled in an oxygen-deficient manner to maintain the temperature in the combustion zone at a temperature of less than 500.degree. F. The gases and volatilized rubber materials and oils are removed from the reactor at a temperature of approximately 350.degree. F.

  • Patent number: 5034021
    Abstract: Apparatus is described for the pyrolysis of coal comprising a pyrolysis tower through which crushed coal and hot gas are counter-currently passed. The tower enables a controlled temperature profile to be maintained in the tower, and contains inner appurtenances which define cascading passageways to promote heat exchange and mixing of the coal with the hot gas. The coal volatiles are carried out of the top of the tower by the gas. The pyrolysis tower may be conjoined with a gasifier so as to most directly utilize the char residuals remaining after pyrolysis of the coal while they are still hot to more efficiently produce a hot synthesis gas, to be used to perform thermal pyrolysis in the tower.

  • Patent number: 4948495
    Abstract: This invention is a continuous retorting process for various high molecular weight organic materials, including oil shale, that yields an enhanced output of liquid product. The organic material, mineral matter, and an acidic catalyst, that appreciably adsorbs alkenes on surface sites at prescribed temperatures, are mixed and introduced into a pyrolyzer. A circulating stream of olefin enriched pyrolysis gas is continuously swept through the organic material and catalyst, whereupon, as the result of pyrolysis, the enhanced liquid product output is provided. Mixed spent organic material, mineral matter, and cool catalyst are continuously withdrawn from the pyrolyzer. Combustion of the spent organic material and mineral matter serves to reheat the catalyst. Olefin depleted pyrolysis gas, from the pyrolyzer, is enriched in olefins and recycled into the pyrolyzer.

  • Patent number: 4894122
    Abstract: A process for the desulphurization of residuals of petroleum distillation in the form of coke particles having an initial sulphur content greater than about 5% by weight. Desulphurization is effected by means of a continuous electrothermal process based on a plurality of sequentially connected fluidized beds into which the coke particles are successively introduced. The necessary heat generation to desulphurize the coke particles is obtained by using the coke particles as an electrical resistance in each fluidized bed by providing a pair of electrodes that extend into the fluidized coke particles and passing an electrical current through the electrodes and through the fluidized coke particles. A last fluidized bed without electrodes is provided for cooling the desulphurized coke particles after the sulphur level has been reduced to less than about 1% by weight.
