Problems solved by technology

First of all, the orange peel has medicinal value and can be used as medicine, and the essential oil extracted from it also has medicinal value, and it is not economically feasible to burn it. Secondly, most of the resin extracted from the roots, branches and leaves by this method can only be burned as fuel oil. , unable to meet the national standard for biodiesel

Embodiment 1

[0044] Use wind to screen, so that the Huyou seeds do not contain impurities such as skin dregs and pomace; use a double-pair roller crusher to crush all the seeds; put the crushed seeds into a softening pot, put about 15% of soft water, and heat up to 70°C, keep warm for 40 minutes to soften all the broken seeds; then transfer them to a frying pan for frying. Make the temperature of the material reach 110°C, and the water content is 8%-10%. Immediately after frying, pour it into the cake press ring to press the cake, so that it is thick in the middle and slightly thinner around it; put it into the oil press while it is hot, and the cake temperature is at 100°C. Stack the cakes; press, and keep the workshop temperature at about 35-38°C; filter the pressed oil to remove impurities such as oil cake slag and foam, and obtain crude oil, which will be crushed and used as fertilizer raw materials; transfer the crude oil to Inject the methanol solution that is dissolved with p-toluen...

Embodiment 2

[0046] Use manual screening to make the shatang orange seeds free of impurities such as pomace and pomace; crush all the seeds with a double pair of roller crushers; put the crushed seeds into a softening pot, add about 10% soft water, and heat up To 70 ℃, keep warm for 35 minutes to soften all the broken seeds; then transfer them to a frying pan for frying. Make the temperature of the material reach 105°C, and the water content is 8%-10%. Immediately after frying, pour it into the cake press ring to press the cake, so that it is thick in the middle and slightly thinner around it; put it into the oil press while it is hot, and the cake temperature is at 100°C. Stack the cakes; press, and keep the workshop temperature at 33-35°C; filter the squeezed oil to remove impurities such as oil cake scum and foam, and obtain crude oil, which will be crushed and used as fertilizer raw materials; transfer the crude oil to the reaction After the kettle, inject methanol solution dissolved w...

Embodiment 3

[0048] Use wind to screen, so that the Yichang orange seeds do not contain impurities such as pomace and pomace; crush all the seeds with a double pair of roller crushers; put the crushed seeds into a softening pot, put about 20% soft water, and heat up to 70°C, keep warm for 45 minutes to soften all the broken seeds; then transfer them to a frying pan for frying. Make the temperature of the material reach 115°C, and the water content is 8%-10%. Immediately after frying, pour it into the cake press ring to press the cake, making it thick in the middle and slightly thinner around it; put it into the oil press while it is hot, and the cake temperature is at 100°C. Stack the cakes; press, and keep the workshop temperature at 33-35°C; filter the squeezed oil to remove impurities such as oil cake scum and foam, and obtain crude oil, which will be crushed and used as fertilizer raw materials; transfer the crude oil to the reaction After the kettle, inject methanol solution dissolved...

Abstract

The invention relates to a method for producing biodiesel by using seeds of a rutaceae citrus plant fruit as a raw material. The method specifically comprises the steps of: extracting grease from citrus seeds, orange seeds or grapefruit seeds as the raw materials, then performing a reactive fractional distillation process on the grease, p-toluenesulfonic acid and methanol and subsequently performing the reactive fractional distillation process on the grease, an alkaline catalyst and methane to obtain a biodiesel product. By adopting the method disclosed by the invention, not only is the problem of the raw materials for producing the biodiesel solved, but also the wastes are changed into valuable things, and the resource utilization of garbage is realized.

Description

technical field [0001] The invention relates to a method for producing biodiesel, in particular to a method for producing biodiesel by using the seeds of Rutaceae citrus fruits as raw materials. Background technique [0002] Biodiesel is a liquid product obtained from recycled sources such as vegetable oils, animal fats and used oils and fats. Because methanol is cheap, easy to recover, and easy to purify, most biodiesel standards (such as EU standard EN14214, American standard ASTMD6751) define biodiesel as fatty acid methyl esters derived from animal and vegetable oils. The power, efficiency, power and climbing ability of biodiesel are comparable to those of ordinary diesel, and other properties are also similar, such as cetane number, viscosity, heat of combustion, pour point, etc. Biodiesel is environmentally friendly, which is reflected in all aspects of the production and combustion process. The production of biodiesel can reduce the exploitation and consumption of p...
