AI Technical Summary

Benefits of technology

This patented technology improves how long it takes for oxygenated fuel (OFC) from being decomposed into water vapor without losing its quality or causing damage during storage. It also prevents harmful substances like nitrogen dioxide that could be released when stored overtime by reacting with metal catalysts used in combustion engines.

Problems solved by technology

This patents discuss how biodieciles like biodigestside could potentially provide alternatives to traditional liquid transportations due to their ability to maintain good qualities over longer periods without being affected by factors like weather conditions during production. Additionally, they highlight the importance of prevention against decomposition reactions between different compounds found within triglicer greases, making them ideal substitutes for crude oil based products. Overall, technical problem addressed in this patented text relates to improving the efficiency at producing pure biofuels while minimizing harmful emissions associated with current methods involving burning fossile organisms.

Embodiment 1

[0022] The oxidation induction time when no antioxidant was added to the sycamore biodiesel was 4.06h; 250 mg / L ginger extract was added to the sycamore biodiesel, and stirred and dissolved at 55°C until all the antioxidants were dissolved and clarified Transparent oily. According to the method in NB / SH / T 0825-2010, the oxidation induction time of the sample at 110°C was determined to be 7.96h.

Embodiment 2

[0024] Add 500 mg / L ginger extract to the phoenix seed biodiesel, and stir and dissolve at 55°C until all the antioxidants are dissolved, and a clear and transparent oil sample is obtained. According to the method in NB / SH / T 0825-2010, the oxidation induction time of the sample at 110°C was determined to be 11.1h.

Embodiment 3

[0026] Add 1000 mg / L ginger extract to the sycamore biodiesel, and stir and dissolve at 55°C until all the antioxidants are dissolved, and a clear and transparent oil sample is obtained. According to the method in NB / SH / T 0825-2010, the oxidation induction time of the sample at 110°C was determined to be 17.13h.

Abstract

The invention provides a natural antioxidant for biodiesel. The main ingredient of the natural antioxidant is a ginger extract. A preparation method adopts the method comprising the following steps: cleaning and decontaminating ginger, cutting the ginger into slices, drying in the sun and smashing, carrying out centrifugal separation after digestion with ethyl alcohol, then using a rotary evaporator to evaporate ethyl alcohol, and thus obtaining the antioxidant. According to the natural antioxidant provided by the invention, the oxidation stability of the biodiesel can be obviously improved, the quality of the biodiesel is greatly improved, and the antioxidant is wide in source, long in effective time, and is a low-cost and reproducible natural antioxidant with certain economic benefit, so that the service life of an oil product can be effectively prolonged. Meanwhile, the added antioxidant has no significant influence on other physicochemical properties of the biodiesel.
