    摘要: The present invention includes systems, apparatus and methods for processing solid waste products. The present invention includes an apparatus and method of processing solid waste products in an autoclave, comprising the steps: (a) loading the autoclave with a charge of solid waste products containing water; (b) sealing the autoclave; (c) rotating the autoclave while heating the autoclave such that the charge of solid waste products containing water creates steam in the autoclave, and whereby so waste liquid water or steam and cellulosic material are produced; (d) conducting liquid water or steam from the autoclave to a water cleaning system and then to a heat recovery steam generator so as to generate steam therefrom; and (d) reintroducing the steam generated by the heat recovery steam generator into the autoclave. The system preferably is a closed loop system to conserve water. The system also includes equipment to convert cellulose into fuels and energy, and some of the fuels and energy are directed to the production of electricity and steam to support the needs of the autoclave and the balance may be commercially sold.

    摘要: A process for the recovery of coal particles from coal tailings is described. The process comprises the steps of initially treating the coal tailings to separate therefrom a proportion of the coal particles having sizes in a specified range, and then subjecting the coal particles to a heat treatment process. In one embodiment, the separated coal particles can undergo an agglomeration in oil prior to the heat treatment. The process provides a further means of recovering coal particles of certain sizes from slurries.

    摘要: Coke is produced from coal by coking the coal, and optionally by drying and/or preheating the coal prior to coking, and further optionally by dry cooling the coke subsequent to coking. At least the coking step is achieved in a pressure tight container which may be a transportable or tippable container. The coking step is performed in the container by conducting a gas through the container in direct or indirect heat exchange relationship with the coal and forming coke. The coking step includes a phase of lump coke formation achieved by heating the coal in a temperature range of between approximately 250.degree. and 600.degree. C. by indirect heat exchange only.
