In the practice of the process, a mixture of carbon-containing materials, a compressed air feed and process steam is fed to the gasifier to produce a synthesis gas. The synthesis gas is fed to the Fischer-Tropsch reactor where it is catalytically reacted to produce heavy hydrocarbons. The outlet from the Fischer-Tropsch reactor is separated into water, a low heating value tail gas, and the desired hydrocarbon liquid product. The water is pressurized and heated to generate process steam. The system further includes a plurality of heat exchangers that enable heat to be recovered from the outlet of the gasifier. The recovered heat is used to make the process steam as well as to preheat the hydrocarbon mix before it is fed to the gasifier and preheat the synthesis gas before it is fed to the Fischer-Tropsch reactor. The method of the present invention greatly increases carbon efficiency and reduces the generation of carbon dioxide.

20170252470 · 2017-09-07 ·

In newly industrialized countries and Third World countries, biogenic waste frequently constitutes a threat to ground water due to its being contaminated with bacteria and germs. In order to decontaminate such biogenic waste, one or more closable sanitizing chambers are fitted with open containers that are filled with the biogenic waste. The sanitizing chambers are closed, and hot waste gases (80° C. to 140° C.) are guided through the sanitizing chambers until germs and bacteria in the biogenic waste are killed. The sanitizing of biogenic waste eliminates the waste as a source of diseases and ground water contamination. The invention is suitable for decentralized locations, for example, in Third World countries or newly industrialized countries or places with stand-alone grids. The invention can have either a stationary or a mobile design.
