Embodiment 1

[0044] 5 grams of fresh kelp raw material (water content 82%) was added to 10 grams of corn stalk carbonized water phase circulating water, and then sent to the reactor after heat exchange in a heat exchanger. The reactor was heated to 280 degrees Celsius and reacted for 30 minutes. The product was subjected to heat exchange in a heat exchanger and was further cooled to 70 degrees Celsius. The product gas was discharged. The remaining products were separated from solid and liquid to obtain 0.135 g of solid product. .

[0045] 3 grams of corn stalk raw material (water content 22%), add 14.43 grams of kelp liquefied water phase circulating water, exchange heat through a heat exchanger, send it to the reactor and heat it up to 230 degrees Celsius, react for 90 minutes, and the product is heat exchanged through the heat exchanger The temperature was lowered to 70 degrees Celsius, the product gas was discharged, and the remaining products were subjected to solid-liquid separation t...

Embodiment 2

[0048] 10 grams of fresh kelp raw material (water content 82%) was added into 20 grams of corn stalk carbonized water phase circulating water, and then sent to the reactor after heat exchange in a heat exchanger. The reactor was heated to 280 degrees Celsius and reacted for 30 minutes. The product was subjected to heat exchange in a heat exchanger and further cooled to 70 degrees Celsius, the product gas was discharged, and the remaining products were subjected to solid-liquid separation to obtain 0.261 g of a solid product. .

[0049] 3 grams of corn stalk raw material (water content 22%), add 28.812 grams of kelp liquefied aqueous phase circulating water, exchange heat through a heat exchanger, send it to the reactor and heat it up to 230 degrees Celsius, react for 90 minutes, and the product is heat exchanged through the heat exchanger The temperature was lowered to 70 degrees Celsius, the product gas was discharged, and the remaining products were subjected to solid-liquid...

Embodiment 3

[0052] 10 grams of fresh kelp raw material (water content 82%) was added to 20 grams of corn stalk carbonized water phase circulating water, and then sent to the reactor after heat exchange in a heat exchanger. The reactor was heated to 340 degrees Celsius and reacted for 20 minutes. The product was subjected to heat exchange in a heat exchanger and further cooled to 70 degrees Celsius, the product gas was discharged, and the remaining products were subjected to solid-liquid separation to obtain 0.288 g of a solid product. .

[0053] 3 grams of corn stalk raw material (water content 22%), add 28.722 grams of kelp liquefied aqueous phase circulating water, exchange heat through a heat exchanger, send it to the reactor and heat it up to 230 degrees Celsius, react for 90 minutes, and the product is heat exchanged through the heat exchanger The temperature was lowered to 70 degrees Celsius, the product gas was discharged, and the remaining products were subjected to solid-liquid s...

Abstract

The invention relates to a method and a device for joint treatment of kelp and straw. The method is to mix the kelp with the second process circulating water, and separate the solid and liquid after heating in the first high-pressure reactor to obtain the first liquid phase separation. Obtain bio-oil and the first process circulating water; mix the straw with the first process circulating water, heat in the second high-pressure reactor and then separate the solid from the liquid, and separate the obtained second liquid phase to obtain biochar and the second Process circulating water. The device includes a kelp storage device, a first batcher, a first heat exchanger, a first high-pressure reactor, a first separator, a straw storage device, a second batcher, a second heat exchanger, and a second high-pressure reactor and a second separator. The method of the invention is a green, energy-saving and efficient renewable resource conversion method, and the device realizes efficient combined treatment of kelp and straw to obtain bio-oil and bio-char.

Description

technical field [0001] The invention relates to the field of renewable resource utilization, in particular to a method and a device for joint treatment of kelp and straw. Background technique [0002] Marine biological resources are rich, large and renewable, providing sustainable and broad resources for the industrial development of new energy and new materials. The use of marine algae to produce biofuels for marine ships, aviation fuels, and land transportation fuels has received extensive attention and technology industry development. [0003] The raw materials of marine macroalgae such as kelp have a very high water content and are converted into energy and materials. Usually, high-energy-consumption drying and dehydration are required first, and then they are processed and converted into liquid, solid and gas fuels or materials. The conversion process consumes a lot of energy. For example, the invention patent CN103468284A discloses a method for producing oil fuel by c...
