Method for producing biodiesel by using fat from animals died of illness

Abstract

The invention relates to a method for producing biodiesel by using fat from animals died of illness, belonging to the intensive agriculture production technology. The biodiesel is produced by using fat of animals died of illness generated after acidolysis in a closed container for preparing amino acid fertilizers, adding low-molecule alcohol compounds, adding appropriate catalysts and maintaining at a certain temperature for a period of time. The result shows that the biodiesel with a conversion rate of 97% above can be obtained when the molar ratio of the fat to the low-molecule alcohol compounds is 1:7 or the volume ratio is 4:1, the use amount of the catalysts (weight/total volume of reactants) is 1.0%, and the temperature is kept for 1.5h at 65 DEG C. By the method, proteins of pigs died of illness for producing amino acid compounds can be subjected to innocent treatment and resource utilization at high efficiency, so that zero-pollution treatment of animals died of illness and high value-added resource utilization are truly realized, and sustainable development of intensive animal husbandry is ensured.

Description

1. Technical field [0001] The invention relates to a method for producing biodiesel from diseased and dead animal fat, which belongs to the agricultural intensive production technology. 2. Background technology [0002] my country's highly scaled breeding industry has increased the normal mortality rate of animals and occurred from time to time. According to statistics, the normal mortality rate in pig breeding in my country is 8-12%, that of poultry is 12-20%, and that of dairy cows is 2-5%. %, encountering sudden epidemics, the animal mortality rate is higher. The littering of sick and dead animals has caused serious environmental pollution. On March 8, 2013, more than 6,600 rotten dead pigs were salvaged from the Huangpu River, which touched people's nerves and caused Chinese people to worry about environmental and water pollution. The State Council and the Ministry of Agriculture Documents have been issued many times to start the treatment of sick and dead animals. Howev...

Problems solved by technology

Both deep burial and incineration do not consider the issue of resource utilization, resulting in a great waste of high-grade organic material resources. The treatment company has no economic benefits, and it is difficult to obtain a long-term mechanism. Moreover, deep burial also has the risk of polluting shallow water and groundwater. , incineration will increase the content of atmospheric PM2.5 and pollute the atmospheric environment

The production of organic fertilizer after high-temperature and high-pressure cooking takes into account the issue of resource utilization. However, due to the low
