Definitions
- the present invention is related to solid agglomerates.
- the present invention relates to a solid cold-pressed agglomerate using an organic binder.
- the cold agglomeration process consists of grouping materials with fine granulometry, in order to obtain a product with larger dimensions through the use of binders. Through this process it is possible to obtain, for example, high quality metallic agglomerates or charcoal briquettes, taking advantage of the fractions made up of smaller particles that would normally be discarded.
- coal briquetting technique has been gaining ground in the industry.
- This technique which can be used for both mineral and charcoal, generally involves the steps of: (i) granulometric balancing of coal or biomass particles; (ii) mixture of binders (binders); (iii) mechanical compaction; and (iv) drying the briquettes.
- the binders used in the briquetting process can be of mineral or organic origin. Such binders play an important role in the formation of briquettes, providing thermoplastic properties (plasticity, tenacity and resistance to compression) to green briquettes and after drying.
- thermoplastic properties plasticity, tenacity and resistance to compression
- One of the most used organic binders in the coal briquetting industry today is corn flour or starch heat treated by extrusion or drum dryer at temperatures between 130 to 150°C.
- the present invention aims to solve the problems mentioned above in a practical and efficient way.
- the present invention has as a first objective to provide a cold-pressed solid agglomerate and a production process for the same that employs a binder that is easy to manufacture, dispensing with the need for equipment, facilities and the use of thermal energy for the industrialization of the binder.
- the present invention has as a second objective to provide a cold-pressed solid agglomerate and a production process thereof that uses a smaller amount of binder.
- the present invention has as a third objective to provide a cold-pressed solid agglomerate and a production process thereof that uses a liquid binder at room temperature, miscible in water, fluid, easy to incorporate, easy dissolution of additives to the mixture and that provides operational practicality.
- the present invention provides a cold-pressed solid agglomerate containing a mixture which, in turn, comprises at least one main compound and at least one organic binder, in which the at least one Organic binder is obtained by the chemical reaction of starch under controlled pH through at least one alkali in aqueous medium and at room temperature.
- the present invention provides a process for producing a cold-pressed solid agglomerate, comprising the steps of (i) mixing at least one main compound with at least one organic binder and (ii) cold-pressing the mixture to an agglomerate is formed, in which the at least one organic binder is obtained by the chemical reaction of starch under controlled pH through at least one alkali in aqueous medium and at room temperature.
- the present invention provides a cold-pressed solid agglomerate and a process for producing the same.
- the cold pressed solid agglomerate of the present invention comprises a mixture which, in turn, contains at least one main compound and at least one organic binder.
- the main compound can be, for example, at least one of biomass, charcoal and coal. Such a compound can be mixture of different coals or biomass, possibly with different compositions and granulometries. Alternatively, the main compound can be at least one metal, which will give rise to a metallic agglomerate.
- the at least one organic binder is obtained by the chemical reaction of starch under controlled pH through at least one alkali in aqueous medium and at room temperature. More preferably, the at least one alkali is sodium hydroxide.
- the at least one organic binder is obtained by means of the reagents in the following proportions by mass:
- the starch to be used in the reaction of the present invention is preferably a regular corn starch, also known as native corn starch.
- the sodium hydroxide employed in the reaction of the present invention is preferably a 10% to 50% sodium hydroxide (aqueous sodium hydroxide solution).
- the at least one organic binder generated in the chemical reaction is in the form, in order to allow the dilution of additives in a practical way.
- the process for producing the cold-pressed solid agglomerate according to the present invention comprises the steps of (i) mixing at least one main compound with at least one organic binder; and (ii) cold pressing the mixture to form the agglomerate, so that the at least one organic binder is obtained by the chemical reaction of starch under controlled pH through at least one alkali in aqueous medium and at room temperature.
- the process of the present invention comprises the step of adding an additive to the mixture prior to the step of pressing the cold mix.
- the process of the present invention comprises the step of drying the solid agglomerate after the step of cold pressing the mixture.
- the solid agglomerate according to the present invention presented results considerably superior to those of the state-of-the-art agglomerate, which uses flour and/or thermo-modified starch as a binder.
- the results presented by the green briquettes demonstrated that the greater degree of gelatinization promoted by the chemical reaction of the binder provided greater adhesion between the particles of the agglomerate and consequently better tenacity performance (drop test) and greater resistance to compression.
- the process for obtaining the organic binder used in the agglomerate of the present invention is not thermomechanical, there is no breakage of the starch molecules, which does not reduce its binding properties.
- the present invention provides a cold-pressed solid agglomerate and a production process for the same that employ a binder that is easy to manufacture, dispensing with the need for extrusion machines and the use of thermal energy for the processing of the starch. Furthermore, the present invention uses a liquid binder, allowing the dissolution of additives in the mixture in an easy and practical way. Finally, the technique of the present invention uses a significantly smaller amount of binder, increasing the purity of the solid agglomerate when compared to the prior art agglomerates.
