Problems solved by technology

The biomass energy currently used by humans mainly comes from land. However, as environmental costs increase, including deforestation, water consumption, greenhouse gas production in the entire production process, and energy efficiency limitations, and as some countries move land from The shift in food production to biofuels has led to higher food prices and increased access to food and nutrition for the poor

Embodiment 1

[0023] Take 30g of the mixture of kelp, reed and water lily, put it in a closed reactor, heat the reactor to 200°C at a heating rate of 5°C / min, react under the condition of 1MPa, and collect the produced product to obtain liquid and / or gaseous fuel.

Embodiment 2

[0025] The raw materials are the same as in Example 1, except that the reactor is heated to 500° C. at a heating rate of 100° C. / min, and the reaction vessel is kept at 29 MPa for 120 minutes, and the resulting product is collected to obtain liquid and gaseous fuels.

Embodiment 3

[0027] The raw materials are the same as those in Example 1, except that the reactor is heated to 300° C. at a heating rate of 45° C. / min, reacted at 15 MPa, and the resulting product is collected to obtain liquid and gaseous fuels.

Abstract

The invention aims at providing a method for preparing fuel with alga and / or hydrophyte as raw materials. The method includes the steps of putting the alga and / or the hydrophyte in an airtight reaction kettle, the reaction vessel is heated to 200 to 500 DEG C at the speed of 5 to 100 DEG C per minute, the reaction is carried out under the condition of 0 to 30MPa, generated gases are collected to obtain gas fuel, and collected liquid is distilled to obtain liquid fuel. The alga and / or the hydrophyte adopted in the invention do not need extra drying, which saves extra energy and simplifies the technique. Therefore, the invention is particularly applicable to preparing biomass materials with high moisture content.

Description

technical field [0001] The invention belongs to the field of comprehensive utilization of biological resources, and relates to a method for preparing fuel by using algae and / or aquatic plants as raw materials, especially suitable for preparing liquid fuel and gaseous fuel by using macroalgae and / or aquatic plants as raw materials. Background technique [0002] It has become a consensus that biomass energy is an ideal energy source that human beings can rely on for a long time. The biomass energy currently used by humans mainly comes from land. However, with the increase of environmental costs, including deforestation, water consumption, greenhouse gas production in the whole production process, and energy efficiency limitations, and as some countries move land from The shift in food production to biofuel production has led to higher food prices, increasing the cost of food and nutrition for the poor. [0003] The ocean covers more than 70% of the earth's surface area and is...
