- hemicellulose sucrose heteropolymer - composed of sugars with 5 carbon atoms, such as xylose and arabinose and 6 carbon atoms such as galactose, glucose and mannose - and glucuronic acid );
- Oils produced by biomass pyrolysis are typically dark, dense and viscous liquids which contain between 15 and 30% water, in addition to sugars, sugar anhydrides, carbonyl and hydroxycarbonyl compounds, monocarboxylic acids and phenolic compounds, the latter being mainly derived. of lignin.
- This complex, multi-product mix is generally an unstable, corrosive mixture and contains health-damaging compounds.
- the compounds present in the mixture undergo dehydroxylation reactions and consequently lose hydrogen in the elimination of water.
- the pyrolysis oil yields are in the range of 30 to 70% and occur with large formation of gas (methane, CO and CO 2 ) as well as coal.
- the process of liquefaction of biomass in the presence of water involves high pressures and temperatures and separates biomass into sugars and aromatics.
- the liquefaction of biomass has already been investigated in the presence of alkaline, alcoholic solutions in the presence of hydrogen and glycerol.
- Biomass liquefaction has also been performed in the presence of maleic and phthalic anhydrides at 190 ° C, with yields of 15-56% of biomass.

- US 2010/0263265 (A1) describes a process for converting biomass into products that can be incorporated into a diesel-type fuel processing plant.
- the process basically comprises: a first phase of fermentation of raw materials of plant origin where, at the end of this fermentation, it is obtained by at least one alcohol and at least one carbonyl group-containing compound; and a second phase corresponding to an acetalization reaction involving said alcohol and said carbonyl group-containing compound.
- US 2013/0014431 (A1) describes a fuel oil composition and a production process thereof. More specifically, a low sulfur biomass-derived combustible oil.
- a low sulfur composition derived from blending the bio-oil with various other heavy and distilled residual fuel oils is obtained, with the final sulfur content and carbon concentration being controlled by relationship between bio-oil and other residual and distilled heavy fuel oils.
- the technique therefore lacks a practical process for modifying a second generation biomass, providing a derivative of this biomass suitable for storage, transport and processing in the various refining processes, so that this derivative has specific characteristics and physicochemical properties for each process.
- a potential application is its use as a cargo to be processed in a refinery.

- the reaction may further be carried out in the presence of solvents or hydrocarbons generally.
- the "opening" may be by conventional heating or microwave heating using conventional solvents of different polarities (acetone, cyclohexane and hexa-decane) and low temperature.
- the process generates a liquid product, henceforth treated throughout the report as stable, low polar, and quite soluble / miscible in petroleum derivatives.
- the obtained bio-oil can be used in various refining processes such as FCC, HPC (Hydroprocessing) as well as in other catalytic processes for obtaining fuels and chemicals and petrochemicals.

- EXAMPLE 1 Obtaining bio-oil (BIO) derived from sugarcane bagasse heated by microwave irradiation.
- the suspension is subjected to microwave irradiation for 30 minutes at a power of 00 W at a set temperature of 55 ° C.
- the suspension was refluxed under conventional heating for 5 hours.
- the sample was allowed to cool and the undigested bagasse was filtered, washed with acetone and then with distilled water to pH 7.
- the solid was oven dried to constant weight.
- the organic phase of acetone was neutralized with solid NaHCO 3 , where approximately 1.0 mL of water was added to accelerate neutralization.
- the acetalization process requires acetone, not only for acetal formation, but also for solvating and solubilizing the formed product, so this example is presented here with the aim of indicating both the decrease in acetone reagent / solvent amount and the process may be carried out in the presence of hydrocarbons, thus providing a mixture ready for storage and processing at the refinery.
- the suspension was refluxed under conventional heating for 5 hours.
- the sample was allowed to cool and the undigested bagasse was filtered, washed with acetone and then with distilled water to pH 7.
- the solid was oven dried to constant weight.
- the organic acetone phase was neutralized with solid NaHCO 3 , where approximately 1.0 mL of water was added to accelerate the neutralization.
- Example 2 For this sequential acetalization experiment, an opening was previously performed as described in Example 2, containing an initial bagasse mass of 1.5 g, being maintained in the same proportions with respect to bagasse and reagent quantities. From the residue obtained in the filtration step was weighed 0.5g.
- the sample was allowed to cool and the undigested bagasse was filtered, washed with acetone and then with distilled water to pH 7.
- the solid was oven dried to constant weight.
- the presence of hydrocarbons does not influence the obtaining of bio-oil (BIO) and the use of this system can facilitate the separation of bio-oil (BIO) from residual biomass (B) and, moreover, provide a mix ready for the refinery.
- the amount of acid (A) depends on the type of acid (A) and the temperature employed. In the case of sulfuric acid and at a temperature of 90 ° C the optimum value of the acid mass ratio shall be within the range 0.147 to 0.074. There is even the possibility of combining Lewis acid (such as FeCl3) and zeolites which can greatly modify the range above.
- Lewis acid such as FeCl3
- reaction time range (R) is quite elastic, for very long times, biodegradation (BIO) degradation can be observed, but this depends on the concentration and type of acid (A) employed.
- Acid-catalyzed acetone (AC) or acetone (AC) / cyclohexane (CH) bio-oils (BIO) generated were also evaluated according to its miscibility in diesel.
- the bio-oil (BIO) was mixed with a conventional diesel fuel in the proportion 5% to 30% (w / w), preferably 15% (w / w). The mixture was mechanically stirred for 30 minutes and allowed to stand, and deposit formation at the bottom of the tube was monitored at different time intervals. It was observed that before mechanical agitation there was a bio-oil (BIO) deposit at the bottom of the test tube, after with agitation there was a dissolution of this bio-oil (BIO) in the diesel and that even after 96 h deposits were formed, proving the miscibility between the bio-oil (BIO) and diesel fractions. No times longer than 96h were measured. The same behavior was observed with the proportion of bio-oil (BIO) at a concentration of 20%.
