Embodiment 1

[0022] Embodiment 1: This embodiment provides a kind of process that utilizes rapeseed oil to prepare marine residual oil:

[0023] First weigh 200g of rapeseed oil, add amine to obtain amine soap, then further increase the temperature, the amine soap is heated to obtain amide, the temperature is further increased, the amide is dehydrated and finally converted into fatty nitrile, the optimal temperature range of the whole process is 300°C~350°C between ℃.

[0024] Then add hydrogen to the obtained fatty nitrile, and react for 5 hours at a pressure of 2 MPa and a temperature of 120° C. to obtain a layered mixed oil.

[0025] Skim off the upper layer liquid of the stratified mixed oil liquid to obtain the heavy oil part of the lower layer.

[0026] Then put the heavy oil part into the cracking reactor, connect the cracking reactor to the liquid receiver, add the cracking catalyst at the same time, add 10g of zeolite to cover and seal, and then heat the reaction until it is heat...

Embodiment 2

[0028] Embodiment 2: This embodiment provides a kind of process utilizing castor oil to prepare marine residual oil:

[0029] First weigh 150g of castor oil, add amine to get amine soap, then further increase the temperature, the amine soap is heated to get amide, the temperature is further raised, the amide is dehydrated and finally converted into fatty nitrile, the optimum temperature range of the whole process is 300°C~350°C between.

[0030] Then add hydrogen to the obtained fatty nitrile, and react for 4.8 hours at a pressure of 2.5 MPa and a temperature of 120° C. to obtain a layered mixed oil.

[0031] Skim off the upper layer liquid of the stratified mixed oil liquid to obtain the heavy oil part of the lower layer.

[0032] Then put the heavy oil part into the cracking reactor, connect the cracking reactor to the liquid receiver, add the cracking catalyst at the same time, add 10g of zeolite to cover and seal, and then heat the reaction until it is heated to 480°C~540...

Embodiment 3

[0034] Embodiment 3: This embodiment provides a kind of process utilizing lard to prepare marine residual oil:

[0035] First weigh 350g of castor oil, add amine to get amine soap, then further increase the temperature, the amine soap is heated to get amide, the temperature is further raised, the amide is dehydrated and finally converted into fatty nitrile, the optimum temperature range of the whole process is 300°C~350°C between.

[0036] Then add hydrogen to the obtained fatty nitrile, and react for 5.8 hours at a pressure of 2.5 MPa and a temperature of 120° C. to obtain a layered mixed oil.

[0037] Skim off the upper layer liquid of the stratified mixed oil liquid to obtain the heavy oil part of the lower layer.

[0038] Then put the heavy oil part into the cracking reactor, connect the cracking reactor to the liquid receiver, add the cracking catalyst at the same time, add 10g of zeolite to cover and seal, and then heat the reaction until it is heated to 480°C~540°C. A...

Description

technical field [0001] The invention belongs to the field of marine fuel oil, in particular to a method for producing marine residual oil by utilizing animal and vegetable oleic acid. Background technique [0002] Marine residual oil is a fuel with high calorific value, good combustion performance, stable storage and wide application range. It is the most economical and ideal material for high power, medium and low speed marine diesel engines. As the number of ships used is increasing, the demand for marine residual oil is also increasing. However, as people's efforts to develop energy are increasing, oil, as a non-renewable energy source, has an important role on the earth. Reserves are getting less and less, therefore, the clean utilization of renewable energy has become a research hotspot at home and abroad. [0003] As more and more countries focus on how to reduce their dependence on oil, they will find a suitable fuel alternative that has a wide range of sources. Und...
