Abstract:
The invention relates to a method for the alkylation of residual hydrocarbons obtained from pyrolytic processes, in particular processes for the obtaining of synthesis gas from wet crushed coal, essentially alkene- and alkane-type waste products, in order the exploit the energy thereof in the form of alkenes, alkanes and alcohols having a high energy content. The method is essentially characterised in that the waste products obtained from the synthesis gas formation are subject to a subsequent treatment in order to transform them into other branched alkane-type products and alcoholic compounds, recovering the hydrogen and water produced in said reactions, that remain available for their subsequent use as fuel in other chemical processing plants, or to be fed back to the gasification-pyrolysis process itself, to enrich the synthesis gas obtained.
Abstract:
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 (H2, O2, steam and CO2) 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.
Abstract:
The device herein described includes: a feeder for feeding wet crushed coal from an upper feed nozzle (1) into two branches (1a and 1b) provided with suitable mills; an element for mixing/distributing screened coal (2), located downstream of the nozzle (1); a gasification chamber (3) located downstream of the aforementioned element (2) where the screened material is oxidised by means of the supply of oxygen at approximately 1,800° C.-1,900° C., said chamber (3) being divided into two sub-chambers by a gas diffusion membrane; a cyclone separator (4) located downstream of the chamber (3), which retains the solid particles present in the synthesis gas; an essentially pyrolytic chamber (5) where the solids carried from the cyclone separator (4) are pyrolysed, the residual gases being fed back into the chamber (3); and a sawtooth screen (6) which collects the solid waste, storing same as slag in a storage element (7).
Abstract:
The invention relates to a method for the production of energy from lower alcohols, particularly methanol, wherein such alcohols are obtained from synthesis gas by means of a process comprising the gasification-pyrolysis of wet crushed coal. According to the method of the invention, the aforementioned alcohols are subject to a catalytic dehydration using a zeolite catalyst as an acid catalyst, giving rise to olefins which in turn, using the same catalyst as a molecular sieve, give rise to highly branched paraffins and cyclic and aromatic compounds, by means of hydrogenation, alkylation and isomerisation, using the hydrogen present in the above-mentioned synthesis gas.
Abstract:
A method for the recovery of energy from synthesis gas waste products obtained from wet crushed coal, according to a gasification-pyrolysis process, which comprises the submission of the waste products obtained during the production of the synthesis gas to a subsequent treatment, to transform such products into other products of the branched-chain alkane type and aromatic compounds, recovering the hydrogen obtained during these reactions, which will be available to be used at other chemical processing plants, as fuel or simply to be fed back to the gasification-pyrolysis process itself, to enrich the synthesis gas obtained.
Abstract:
The collector rests on a ball joint by means of which it is connected to the ground, said ball joint being surrounded by a series of hydraulic arms arranged in two imaginary concentric rings. The aforementioned arms are hinged at the ends thereof to the collector and the corresponding foundation. In addition, the structure is stabilized by at least four towers (12) connected in pairs by a cable (13) that follows a closed path and is rigidly secured to the structure (2) at two diametrically opposed points of attachment (14), in such a way that the collector is pulled in one direction or another by means of multiple pulleys associated with the lower and upper ends of each of the two opposing towers, said cable passing through a braking means (17).
Abstract:
The aim of this invention consists in modules of parabolic mirrors (1) of 0 to 100 metres of diameter, supported on a solar tank (3) with watery solution of MgC12 (2). This system uses the reflection and refraction of the solar energy to produce other types of energy in a clean manner.Each mirror possesses a mobile system (8), which makes it swing with a solid angle of 30° towards the east and west; it also possesses a tower or shaft (6) of 0 to 100 metres of height. In the top is located a spheroid of graphite (7), covered with zirconium carbide and where the energy is transferred to be conducted by other fluids (water, gas, etc.). Here is located a lens Fresnel, by which is obtained a high concentration of light energy, which is used in obtaining pure silicon by its evaporation. The energy of radiation is used for obtaining electric energy. The conduction of the captivated energy is realized by steel conductions of high resistance through the shaft (6). The excess energy is stored in the dissolution of the solar tank (2) to be later transformed into electric energy, hydrogen, drinking water, fuels and by-products of nitrogen, which gives us the independency between the sectors: electric energy, drinking water and chemical industry.
