The procedure according to the invention allows the obtaining of lower alcohols from the solar energy produced at a high temperature solar thermal power plant which provides, from an energy point of view, the power supply necessary for every step of the procedure, supplying both the electricity power necessary to perform the intermediate steps of the procedure and, essentially, the products involved in the different steps (H, O, steam and CO) starting from a supply of wet milled coal, wherein the by-products obtained during these different stages of the procedure are fed back to the procedure itself. The procedure allows the storage of the energy obtained from the sun as lower alcohols, and such alcohols, in turn, may become an alternative to the consumption of fossil fuels, eliminating the risk derived from the production of residues; consequently, it is an especially advantageous procedure, both from an environmental and a production point of view. 1. Industrial procedure to obtain lower alcohols from solar energy , characterised in that it comprises the following stages:{'sub': 2', '2', '2, 'i) gasification/pyrolysis at a dual reactor, to obtain syngas: the water vapour from a high temperature solar thermal power plant is fed to a dual gasification/pyrolysis reactor where wet milled coal has been previously fed through a feeding hopper, and such coal is partly oxidized by the Oobtained from a subsequent electrolysis stage (stage 2), and by the water vapour from the solar plant at a gasifier provided inside the dual reactor; the gas thus obtained is subsequently subject to a pyrolysis, removing the free carbon, the HS and part of CO, using the appropriate catalysts to obtain syngas.'}{'sub': '2', 'ii) Electrolysis in parallel to obtain hydrogen and oxygen: the mixture of water vapour and residual COobtained at the stage i) passes through a turbine/engine to generate, by means of a dynamo, the power required to unleash an electrolysis reaction at the appropriate ...
