Embodiment 1

[0027] In the first step, the wheat straw is put into a hot extrusion molding machine, and a solid with a carbon content of 99.9wt% is produced under the conditions of 720°C and 350MPa.

[0028] In the second step, the solid matter is put into the gasifier and gasified at 870°C to produce a synthesis gas containing 62.4vol% hydrogen and 29.2vol% carbon monoxide (the remaining components are CO 2 and CH 4 Wait).

[0029] In the third step, the synthetic gas is purified and compressed and introduced into the Fischer-Tropsch synthesis tower to produce biofuel with 1.5 vol% C2-C4 hydrocarbons, 4.2 vol% C5-C8 hydrocarbons, and 93.6 vol% hydrocarbons above C9.

Embodiment 2

[0031] In the first step, the straw is put into a hot extrusion molding machine, and a solid with a carbon content of 52.1 wt% is obtained under the conditions of 1180° C. and 0.0001 MPa.

[0032] In the second step, the solid matter is put into the gasifier and gasified at 1200°C to produce a synthesis gas containing 80.0vol% hydrogen and 18.9vol% carbon monoxide (the remaining components are CO 2 and CH 4 Wait).

[0033] In the third step, the synthetic gas is purified and compressed and introduced into the Fischer-Tropsch synthesis tower to produce biofuel with 1.0 vol% C2-C4 hydrocarbons, 3.0 vol% C5-C8 hydrocarbons, and 94.1 vol% hydrocarbons above C9.

Embodiment 3

[0035] In the first step, the bagasse is put into a hot extrusion molding machine, and a solid with a carbon content of 73.5wt% is prepared under the conditions of 350° C. and 56 MPa.

[0036] In the second step, the solid matter is put into the gasifier and gasified at 180°C to produce a synthesis gas containing 24.0vol% hydrogen and 40.0vol% carbon monoxide (the remaining components are CO 2 and CH 4 Wait).

[0037] In the third step, the synthetic gas is purified and compressed and introduced into the Fischer-Tropsch synthesis tower to produce biofuel with 3.0 vol% C2-C4 hydrocarbons, 3.9 vol% C5-C8 hydrocarbons, and 90.0 vol% hydrocarbons above C9.

Abstract

The invention discloses a method for biological fuel oil. In the method, biological matter, mineral matter, household garbage and urban sludge are used as raw materials, and the raw materials are dehydrated and carbonized into a high-carbon content solid with a certain shape and size by a thermal-extrusion molding technique and then are prepared into the novel biological fuel oil by adopting a gasification process and Fischer-Tropsch synthesis. The method has the advantages of wide range of the raw materials, low production cost and high gasification and Fischer-Tropsch synthesizing efficiency and is easy to control the production process, and the biological fuel oil has the advantages of high yield and good quality and is suitable for industrial production.

Description

technical field [0001] The invention relates to the fields of energy, energy conservation and environmental protection, and specifically refers to a high-efficiency preparation method of a novel biofuel. Background technique [0002] With the rapid development of my country's economy, the number of automobiles has increased rapidly. According to statistics from the Traffic Management Bureau of the Ministry of Public Security, the number of motor vehicles in my country has reached 199 million at the end of September 2010. Due to the rapid increase in car ownership, China's dependence on foreign oil has also increased. According to data from the China Petroleum and Chemical Industry Federation, in the first half of 2010, China's apparent consumption of petroleum reached 220 million tons, a year-on-year increase of 15.1%, and its dependence on foreign countries was as high as 55%. According to the current growth momentum of car ownership, it is estimated that my country's oil ...
