Fuel gas with high calorific value, preparation method thereof and equipment for carrying out the preparation method

Abstract

The invention relates to a fuel gas with a high calorific value, a preparation method thereof, and equipment for carrying out the preparation method. The equipment comprises a control system, a water ion electrolysis system, and a hydrocarbon compound reforming system. The control system collects the data of time, pressure, temperature, and material feeding and automatically carries out management. The equipment has the advantages of safety, reliability, easiness in application, and convenience in control. The prepared fuel gas has a high calorific value, which can reach 11000 to 51000 Kcal / cm3, and does not contain any sulfur or nitrogen element. Compared to the conventional fuels, the energy and cost can be saved by 50% or more, and the fuel gas has the characteristics of cleanness, environment-friendliness, and high calorific value.

Description

Technical field [0001] The invention relates to a gas fuel preparation equipment and a method thereof and the high calorific value fuel gas prepared therefrom, in particular to a mixture of proton hydrate and hydroxide ion produced by the preparation equipment electrolyzing water, and then reforming with alkane The high calorific value gas produced afterwards. Background technique [0002] With the development of the economy, the fuel consumption of countries around the world is increasing year by year. According to incomplete statistics, the current annual fuel consumption in my country has exceeded 450 million tons. The huge fuel consumption not only puts huge pressure on the increasingly depleted petroleum energy, but also the floating carbon, hydrocarbons (HC), carbon monoxide (CO), nitrogen oxides (NOx), sulfur dioxide (SO2), etc. produced by fuel consumption are the environment The source of pollution seriously affects people's quality of life and health. [0003] Based on ...

Problems solved by technology

[0004] At present, the production and preparation methods of hydrogen mainly include ① hydrogen production from fossil energy resources; ② hydrogen production from biomass and microbial hydrogen production; ③ hydrogen production from water decomposition, etc. Widely used, take electrolysis of water to produce hydrogen as an example: water can be directly split into hydrogen and oxygen with electric energy. When hydrogen gas is generated, and an appropriate amount of NaCl, KOH and other electrolytes are added to pure water, in an ideal state, the voltage of 1.47V passes through the electrolyte aqueous solution, and the efficiency of water decomposition into hydrogen and oxygen can reach more than 90%, but the production of 1kg of hydrogen gas is about It needs 50-58KWH of electric energy. It can be seen that the cost of using electrolyzed water to produce hydrogen is relatively high. From an economic point of view, there is no cost advantage compared with other fuels.

[0005] At the same time, because hydrogen is a highly volatile, combustible, and explosive substance, unsafe factors are also the main problems that limit its application. Experiments have shown that ① the combustion limit of hydrogen in air is very wide, and the hydrogen content reaches 4% by volume. ~70% can be burned, which is much wider than the combustion limit of gasoline of 1.3% ~ 7.6%; ②The minimum energy required to ignite hydrogen is only 0.005mcal, and the flame of hydrogen combustion has no color and is not easy to find; ③High pressure hydrogen and low temperature Liquid hydrogen is easy to leak and has high storage requirements
