PROCESS USING SOLAR ENERGY, MICROWAVES AND PLASMAS TO PRODUCE A LIQUID FUEL AND HYDROGEN FROM BIOMASS OR COAL

摘要

This invention consists in a system for using heat energy (heat) of solar origin coupled to microwaves and plasmas to produce mainly carbon monoxide (CO), dihydrogen H2 from carbon compounds ( biomass, household waste, sludge from wastewater, fossil coal), the gaseous mixture obtained makes it possible, among other things, to produce hydrocarbons (olefins paraffins), esters, alcohols by Fischer-Tropsch synthesis. The invention makes it possible in a first step for the roasting and pyrolysis of carbonaceous compounds to produce, on the one hand, char or dry coal and a mixture of superheated gases containing mainly CO2, water vapor, tars and uncondensable volatiles; in a second step, from the products of the pyrolysis (char or coal, gas mixture), the process makes it possible to produce a syngas, composed mainly of a mixture of carbon monoxide and dihydrogen, a mixture which will be used in Fischer-Tropsch synthesis units. The products of the synthesis after the Fischer-Tropsch step will be separated by a distillation column after heating in solar ovens or mixed ovens (solar / microwaves). The electrical energy required for the production of plasma will be produced by solar panels, wind turbines, generators operating from non-recoverable hydrocarbon gases after distillation, and thermal energy recovery systems on the whole process.
