20160017235 | PROCESS FOR TREATING WASTE FEEDSTOCK AND GASIFIER FOR SAME - A process for treating a waste feedstock using a gasifier and the gasifier for same. Hot exhaust from an engine travels through a series of hollow heating plates stacked vertically within a gasifier reactor with spaces between each set of successive heating plates forming reaction zones. Each reaction zone is divided into an upper treatment area and a lower treatment area by a rotating disk. Waste material travels from an outer feed spot along the top surface of the rotating disk radially inwardly to a drop area located at the radially innermost portion where it drops to the top surface of the hollow heating plate below. The waste material is then conveyed radially outward to a chute to the next reaction zone or once fully processed to an exit from the reactor. Vapors from the waste material are drawn off each reaction zone through an outlet for further processing. | 01-21-2016 |

20160108809 | INTEGRATED INSTALLATION AND METHOD FOR FLEXIBLY USING ELECTRICITY - The present invention relates to an integrated plant which comprises a plant for the electrothermic production of hydrogen cyanide and a plant for electricity generation, the plant for the electrothermic production of hydrogen cyanide being connected to the plant for electricity generation via a conduit and electricity being generated in the plant for electricity generation from a product gas obtained in the plant for the electrothermic production of hydrogen cyanide. This integrated plant affords flexible use of electricity by a method in which, at times of a high electricity supply, the plant for the electrothermic production of hydrogen cyanide is operated and at least some of the hydrogen and/or gaseous hydrocarbons obtained in addition to hydrogen cyanide is stored and, at times of a low electricity supply, stored hydrogen and/or gaseous hydrocarbons are fed to the plant for electricity generation. | 04-21-2016 |
20160146105 | Method and Device for Converting Municipal Waste Into Energy - A method and device for converting municipal waste into energy. This method involves heating the waste in multiple sections of a chamber to produce syngas and biochar. The syngas is removed with a vacuum pump and the biochar advances to the next section and is heated to a higher temperature to release more syngas. All of the collected syngas is then transferred to a bio-reactor that removes dangerous carbon monoxide from the syngas mixture by combining the syngas with hydrogen, causing the carbon monoxide to react with the hydrogen and produce methane and water. The resulting syngas can then be used for electricity production or stored as dimethyl ether. | 05-26-2016 |
