Benefits of technology

This technology allows for better control over both the amount of fuel being burned (F) or how much air needs to be added compared to what it can produce without burning up too many resources like fossil fuels. It achieves this through combining different types of gases such as FGHs from coal and H2O/CO2. By performing these reactions separately at certain ratios, less heat input occurs while producing more hydrocarbons than before combustion. Additionally, the use of an intermediate fluid called synethea makes it easier to mix them properly evenly. Overall, this new way helps reduce thermal stress on equipment and improve operational performance.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the proportioning accuracy between certain gases found within fuel compositions made through various methods like steam reforming processes that require specific conditions including proper addition of oxygen sources and coolants.

Embodiment

[0125] The flow rate of the first pulverized coal gasification synthesis gas is 615350Nm / h, the second pulverized coal gasification synthesis gas flow rate is 615350Nm / h, and the coal water slurry gasification synthesis gas flow rate is 303997.8Nm / h.

[0126] exist figure 1 In the device shown, the first pulverized coal gasification synthesis gas from the first pulverized coal gas filter is divided into three paths:

[0127] After the first pulverized coal gasification synthesis gas (10%) comes out from outlet 1 of the first pulverized coal gas filter, it passes through the first pulverized coal gas mixer and comes out with a stream of coal water from coal water slurry gas filter outlet 1. The slurry gasification synthesis gas is mixed, then heated to about 255°C by the first gas preheater, and then enters the first shift furnace, and the shift reaction is carried out at 3.92MPaG and 255°C.

[0128]The shifted gas after the first CO shift reaction, temperature: ~450°C, CO

Abstract

The invention provides a pulverized coal synthesis gas and coal water slurry synthesis gas ratio conversion process, which comprises the following steps of: proportionally and jointly carrying out COconversion reaction on coal water slurry synthesis gas and pulverized coal synthesis gas, further dividing the coal water slurry synthesis gas into two streams, dividing the pulverized coal synthesisgas into three streams, and carrying out mixing according to a specific distribution ratio and a specific mixing mode. The problem that the temperature of a catalyst bed is increased and decreased slowly is solved, meanwhile, the operation difficulty of carbon-hydrogen ratio adjustment is reduced, the overall energy consumption of the system is reduced, and the overall operation efficiency is improved. Moreover, the coal water slurry is prepared by utilizing synthesis water generated by indirect coal liquefaction, and synthesis gas is generated by utilizing the coal water slurry, so that not only is the synthesis water generated by indirect coal liquefaction recycled, but also the energy consumption generated during sewage treatment is reduced. The invention further provides a pulverized coal synthesis gas and coal water slurry synthesis gas ratio conversion device.
