Quick hydropyrolysis reactor and process thereof

Abstract

The invention discloses a quick hydropyrolysis reactor and a process thereof and relates to pyrolysis of coal, solving the problems that the exiting pyrolysis process is high in energy consumption and low in oil extraction rate. A reactor is provided with a synthesis gas nozzle, a hydrogen nozzle and a coal ash nozzle as well as temperature measuring points of the reactor, wherein the synthesis gas nozzle is communicated with a natural gas and oxygen inlet pipe and is further communicated with a cooling water inlet / outlet; a chilling tank is communicated with the bottom of the reactor, the chilling tank is connected with a water inlet and a water outlet, and the chilling tank is provided with a cooling water nozzle, temperature measuring points of the chilling tank and an outlet of a chilling room. The process comprises the following steps: firstly, feeding the synthesis gas into the reactor; conveying coal ash for quick pyrolysis reaction in a hydrogen atmosphere; and then quickly decreasing the temperature to terminate reaction. The reactor and process disclosed by the invention are used for the coal-to-oil field and have the advantages of simple structure, low energy consumption, high coal conversion rate and high oil product yield.

Description

technical field [0001] The invention belongs to the field of coal-to-oil production, in particular to a coal pyrolysis furnace, in particular to a rapid hydrogenation pyrolysis entrained-bed reactor and a process thereof. Background technique [0002] Energy is the foundation of national economic development. my country's energy structure is characterized by "rich coal, little gas, and oil shortage". At present, my country's proven oil reserves are 24.8 billion tons and natural gas reserves are 4.4 trillion m 3 , and coal reserves exceed 1 trillion tons. In 2011, my country produced 3.52 billion tons of coal, 201 million tons of crude oil, and 101.115 billion m3 of natural gas. 3 , Coal consumption accounts for more than 70% of the overall energy consumption. Judging from the reserve data, coal will play a dominant role in my country's energy consumption structure for a long time. Judging from the trend of my country's energy consumption structure in the future, the prop...
