Definitions
- Solid petroleum-derived paraffins have a high content of carcinogenic contaminants, which does not allow them to be suitable for applications in the pharmaceutical or food industry, particularly due to the presence of polynuclear aromatic hydrocarbons (PNA's).
- PNA's polynuclear aromatic hydrocarbons
- the paraffins obtained by the process of the present invention lack such hydrocarbons, which makes them optimal for the pharmaceutical and food industry.
- the diesel obtained contains Cu to C ia paraffins with less than 5ppm sulfur, with a normal isoparaffin / paraffin ratio of 2 to 8, with oxygenated compounds less than 0.6% by weight, with less than 0.4% by weight of fatty acids , with less than 10% by weight of alkylcyclohexane and less than 15% by weight of alkylbenzene.
- the hydrodeoxygenation and hydroisomerization conditions are: 300 to 45O 0 C temperature, 1.0 to 6.0 MPa pressure, between 0.5 to 5h "1 space velocity and 500 to 2000 LN of H 2 / L load.
- the application EP 0126168 was located, related to a process for the selective reduction of edible oils and fats, which uses a catalyst in a fixed bed to carry out a process of hydrogenation
- the document teaches the hydrogenation method and the types of vegetable oils that can be used, including palm oil.
- This process employs nickel catalysts and the hydrotreatment conditions are: 150 to 260 ° C temperature, around 11.0 MPa and 0.2 to 2Oh "1 space velocity.
- patent application EP 1857525 discloses a process for obtaining light n-paraffins from the hydrogenation of a mixture of vegetable and mineral oils in a ratio of 100: 1 or 1: 100 a a temperature of 250 to 400 ° C, 7.0 to 15.0 MPa, 0.5 to 2h "1 of space velocity and 200 to 1000LN of H 2 / L load.
- the claimed process comprises the stages of preheating, mixing of oil with hydrogen, heating, reaction and separation by decantation and possibly distillation or crystallization, as shown in Figure 1.
- the sequence of steps that characterize the invention is explained by continuation:
- the organic oil at a temperature between 50 and 100 0 C, to make it fluid and to transfer it to the later stages of the process.
- the oil and hydrogen are mixed in the pipe and passed through an oven to heat it to the desired reaction temperature.
- hydrogen reacts with the oil on the active sites of the catalyst at pressures between 2 and 11 MPa and temperatures between 15O 0 C and 330 ° C, with a spatial velocity between 0.2 and 6 h '1 .
- the catalyst used is a fixed bed composed of nickel and molybdenum oxides supported by alumina that were previously sulfurized for activation.
- the hydrotreated product exits the lower part of the reactor and passes to a level separator, where the gas is removed by the upper part and the liquid product hydrotreated by the bottom.
- the latter is composed of two phases (water and paraffin), which are separated by decantation and according to the desired concentration of high paraffins molecular weight a distillation separation step can be performed, to remove paraffins of lower molecular weight.
- the operational conditions that is to say pressure, temperature, spatial velocity and hydrogen / charge ratio, to obtain the solid state product in the reaction stage, are specific for each catalyst, whether fresh or used, and are determined according to a preset protocol.
- FIG 1 shows the detail of the flow diagram of the hydrotreatment unit where the solid paraffin is obtained.
- the load to be processed which in this case is vegetable oil or animal fat, is introduced into the loading drum (1), from where it is pumped and mixed (2) with hydrogen to pass to the heating furnace (3) where The oil-hydrogen mixture acquires the appropriate temperature to pass to the reactor (4).
- the products of the reaction or they pass to the separation system by decantation (5), which is generally made up of several stages to achieve the required qualities. The most convenient conformation of the separation stages by decantation is sufficiently known and used by the hydrotreatment industry. In this stage, three main comments are obtained: a gas formed by hydrogen together with the reaction gases; a liquid phase constituted by the products obtained from the oil and another liquid phase corresponding to the water byproduct of the reaction (C).
- a distillation separation (8) may be required to separate the paraffins of lower molecular weight that are in the diesel range (B) from the paraffins and solid compounds (A).
- the gas phase obtained in stage (5) passes to a cleaning stage (6) to purify the hydrogen from the gases produced during the reaction such as CO, CO 2 and methane by washing techniques known in the industry, to obtain a hydrogen High purity which is compressed (7) and mixed with replacement hydrogen to maintain inventory and recycled before the heating and reaction stages.
- the claimed process comprises the steps shown in the flow chart of Figure 1, where from the storage tank (1), with heating, the vegetable oil, algae or other vegetable origin or Ia Animal fat is pumped in the oven (3). Vegetable oil or Ia Animal fat is combined with hydrogen in the mixer (2), which can be located before or after the oven (3), where the load is heated to the desired temperature at the reactor inlet (4). In the reactor (4), the reaction is carried out, which being exothermic causes the temperature of the load to increase as it passes through the catalytic bed. The product of the reaction is taken to a separating vessel (5), where the gaseous hydrogen is recovered to purify it (6) and recirculate it to the process. Water and solid paraffinic compounds, which due to the high process temperatures are still kept in a liquid state, are separated by decantation. Said paraffinic compounds are recovered for storage.
- stage 3 Pass the mixture of stage 3 through a reactor filled with a catalyst selected from the group comprising CoMo, NiMo, NiW,
- CoW which have undergone a sulfurization process and supported on ⁇ -alumina.
- the hydrotreatment reaction is carried out at a temperature between 150 0 C and 330 0 C, a pressure between 2 MPa and 11 MPa, a space velocity between 0.5 h "1 and 6 h " 1 and a hydrogen ratio per oil charge between 300 L of H 2 per liter of oil and 500 L of H 2 per liter of oil, which allows the reactions that transform the oil into solid paraffins.
- solid paraffins are taken to a process of separation by distillation or crystallization where the lightest and heavy molecules are separated according to the quality that is required.
- the operational reaction conditions ie pressure, temperature, space velocity, to obtain the solid state product are specific to each catalyst, whether fresh or used, and are determined according to a pre-established protocol in which two variables are set and the third one is established in order to prevent the formation of light paraffins.
- the applicant considers that in this way the hydrotreatment reaction is interrupted before the molecules become saturated with hydrogen, with which free radicals are produced that subsequently combine to form high molecular weight paraffinic compounds, which They are solid at room temperature.
- the catalyst is a fresh or used catalyst, comprising a porous alumina support impregnated with metal sulphides from Ni and Mo or Ni and Co.
- the vegetable oil is selected from the following group of oils: soybean oil, palm oil, cane oil, fig oil, jatropha oil, among others.
- the solid paraffinic compounds that are produced by the process described herein have their main use in candle making.
- the paraffinic compounds obtained are of high refining and purity and are safe to use as paper coatings for packaging, prepare, transport, treat or store food with which you must have contact.
- the solid paraffins of the invention can also be used in corrugated contents to pack vegetables, fruits, meat, fish and cheeses; as well as in paper cups. They are also used in canned lids to preserve food from dehydration and mold formation. Additionally, they are added to chewing gums for their plasticity.
- Tables 2 and 3 show the analytical results of the solid paraffin obtained in the pilot plant, which has a low aromatic content.
- Table 3 Chemical composition of solid paraffin.
- Table 4 shows the results of the comparative analysis of the absorbance for the paraffin of the invention and the paraffin obtained from a petroleum derivative, compared with the standards established for the paraffin according to the FDA.
