1. 1) PROCESS FOR IMPREGNING VEGETABLE CHARCOAL AND BRIQUETTES WITH LIQUID AND GEL ALCOHOL, where the vegetable charcoal undergoes a process characterized by comprising the following steps: - In the first step, charcoal of suitable granulometry is selected, which must be dry, clean and free of impurities; - In the second step, the selected charcoal is immersed in liquid alcohol inside a closed container, in the proportion of 1.8 to 2.5 liters of liquid alcohol for each 1 kg of charcoal, and the charcoal must remain completely submerged for an immersion time between 10 and 15 hours; - In the third step, the charcoal impregnated with liquid alcohol is transferred to a container containing gel alcohol, using approximately 1.3 to 1.8 liters of gel alcohol for each 1 kg of charcoal; the impregnation and treatment are carried out in an ambient temperature range between 18°C and 27°C, and in an environment with controlled ventilation; - In the fourth and final stage, after the immersion period in the gel alcohol, the charcoal is removed from the container and drained to eliminate excess liquid alcohol; the process is conducted under the same temperature and ventilation conditions as the previous stages.
2. 2) A PROCESS FOR IMPREGNATING VEGETABLE CHARCOAL AND BRIQUETTES WITH LIQUID AND GEL ALCOHOL, according to claim 1, is characterized by the process of impregnating liquid alcohol and gel alcohol into briquettes.

Description

BRIEF PRESENTATION [001] This patent application relates to a process for impregnating charcoal and briquettes with liquid and gel alcohol, the highlight of which is a charcoal treatment process involving initial immersion in liquid alcohol followed by impregnation with gel alcohol, under controlled temperature and ventilation conditions, using specific alcohol proportions to optimize absorption by the charcoal. This invention significantly increases the efficiency of charcoal combustion, providing faster ignition, prolonged combustion, and reduced waste generation. Thus, this invention promotes greater fuel economy, ease of ignition, and cleaner, more efficient burning, being especially applicable in uses such as barbecues and other activities that require high-quality charcoal. FIELD OF THE INVENTION [002] The invention described in this patent application is geared towards the field of solid fuel technology and coal treatment processes, specifically applicable to improving the performance of coals used in activities such as barbecues, home heating and other applications that demand efficient, fast combustion with less environmental impact. PROBLEM TO BE SOLVED [003] It is known to experts in the field that the low efficiency of absorption and retention of liquid fuels by coal results in less efficient combustion, difficulty in ignition and greater generation of waste. In other words, it is a significant problem, given that it directly impacts the performance of coal used in activities such as barbecues, domestic heating, among others, where energy efficiency, speed of ignition and cleanliness of combustion are crucial factors for the end user. [004] The technologies and methods currently known, although functional, cannot adequately optimize the absorption of fuels by coal, leading to combustion that does not maximize the energy potential of the material, thus resulting in higher coal consumption, increased costs for the user, and greater production of waste and smoke, which can have negative environmental implications. CURRENT STATE OF THE ART [005] The document BR 112022007606-1, published on 19/07/2022, is known from the current state of the art and describes a method for producing charcoal by obtaining a raw material that includes cellulose, hemicellulose and/or lignin, contacting the raw material with a metallic salt (such as FeCl3) and, optionally, a carbonate salt (such as Na2CO3) in an aqueous medium to form a reaction mixture and heating the reaction mixture to at least 90°C for at least 30 minutes to generate a suspension that includes the charcoal. The inorganic material is leached from this charcoal, which is then compressed. Suitable raw materials include sawn timber or other wood waste, garden waste, paper waste and/or biomass. The metallic salt and/or carbonate salt can be supplied from 1% to 30% of the dry weight of the raw material. [006] However, the prior art mentioned above is cited only to establish the state of the art, given that no more relevant document has been obtained regarding the subject matter claimed in this patent application. OBJECTIVES OF THE INVENTION [007] The objective of the present invention is to increase the absorption and retention efficiency of liquid fuels by charcoal and briquettes, significantly improving their combustion. [008] It is also an objective of the present invention to facilitate the lighting of charcoal and briquettes, providing a quick and efficient ignition, without the need for additional combustion accelerators. [009] Furthermore, it is an objective of the present invention to reduce the amount of waste and smoke produced during the burning of charcoal and briquettes, contributing to a more economical and environmentally sustainable use. [010] Another objective of the present invention is to extend the burning time of charcoal and briquettes, increasing energy efficiency and reducing material consumption during their use in activities such as barbecues and domestic heating. SUMMARY OF THE INVENTION [011] The present invention solves the problem of low absorption and retention efficiency of liquid fuels by charcoal and briquettes, which negatively impacts combustion, ignition, and waste generation. The invention is characterized by a charcoal and briquette impregnation process, which involves initial immersion in liquid alcohol followed by the application of gel alcohol, under controlled temperature and ventilation conditions. The present invention promotes more efficient and prolonged combustion, facilitating the rapid ignition of charcoal and briquettes, and eliminating the need for additional combustion accelerators. Furthermore, the present invention reduces waste and smoke production, contributing to a more economical and sustainable use of charcoal and briquettes. ADVANTAGES OF THE INVENTION [012] The present invention offers the following advantages: Increases the efficiency of fuel absorption by charcoal and briquettes, maximizing the
