Method for producing methane-like liquid gas by plant carbonization

Abstract

The invention disclosed a plant carbonizing way to produce methane liquefied gas which uses the carbonized botanical carbon as the material. The producing procedure includes the following steps: burning the mentioned botanical carbon at high temperature in the gasifying stove, while burning, charging air, water steam to the stove to produce CO, CO2, H2 and other gas; dusting, cooling and cleaningthe gas; transforming the gas into methane through methane transforming process; high pressure liquating the gas to get the mixed fuel gas in which methane is the main ingredient, it also contains COand H2. The sewage, dreg discharge and air pollution is less than the traditional method which uses coal to produce water gas or liquefied gas; the invention has many advantages such as environment-friendly, easily available material and simple technology; besides, it needs low equipment investment and operating cost.

Description

technical field [0001] The invention belongs to the application field of renewable green energy, and in particular relates to a method in which plants are carbonized, burned in a gasification furnace to produce mixed combustible gas, and then synthesized by methanation to produce methane liquefied gas. Background technique [0002] Liquefied petroleum gas as a fuel-type energy has been increasingly used in civil or industrial fields. Earlier, urban residents first used wood as fuel, and then mostly used coal as fuel. With the increase of forest resources in our country Reduction, restrictions on wood felling, now it is difficult to see the use of wood as fuel in cities, and when coal is used as living fuel, due to the production of a large amount of carbon dioxide and carbon monoxide, especially sulfide gas, the air pollution is serious. As a result, the incidence of residents' respiratory system and cardiovascular system has been increasing, so the use of coal has been cons...

[0002] Liquefied petroleum gas as a fuel-type energy has been increasingly used in civil or industrial fields. Earlier, urban residents first used wood as fuel, and then mostly used coal as fuel. With the increase of forest resources in our country Reduction, restrictions on wood felling, now it is difficult to see the use of wood as fuel in cities, and when coal is used as living fuel, due to the production of a large amount of carbon dioxide and carbon monoxide, especially sulfide gas, the air pollution is serious. As a result, the incidence of residents' respiratory system and cardiovascular system has been increasing, so the use of coal has been considerably restricted in many cities, and liquefied gas has been replaced; although most rural areas in our country still use ancient coal Stoves use orange stalks and wood mostly as fuel, but their thermal efficiency is low (only 13%), and they are easy to pollute the environment. Therefore, they are also facing conversion to the direction of using liquefied gas, which makes the demand for liquefied gas Especially with the rapid development of China's economic construction and the substantial improvement of people's living standards, China's energy consumption is also increasing day by day, and fossil energy such as coal, oil, and natural gas used to produce liquefied gas is also increasing. On the other hand, China's oil resources are not rich, and the population is very low, and the per capita ownership is extremely low. In addition, the international situation is constantly changing, which has led to the high price of petroleum liquefied gas, which has seriously affected the lives of residents. The use of fuel, the search for renewable energy, has become an urgent need today
