Abstract
The invention discloses an oil inlet distribution pipe used in a wood tar fluidized bed hydrogenation reactor to solve the problem that the existing oil inlet distribution pipe easily causes coking of wood tar. The oil inlet distribution pipe (9) includes the oil inlet pipe (1) and the cooling water jacket located outside it, and is composed of a horizontal pipe section and a vertical pipe section, and the vertical pipe section is located in the middle area of the wood tar ebullated bed hydrogenation reactor (10). The cooling water sleeve includes an inner sleeve (2) and an outer sleeve (3); a first cooling water channel (6) is formed between the inner sleeve and the oil inlet pipe, and a second cooling water channel (7) is formed between the inner sleeve and the outer sleeve . In the vertical pipe section of the oil inlet distribution pipe, a flared pipe (8) is provided between the bottom end of the oil inlet pipe and the bottom end of the outer sleeve as the outlet of the oil inlet distribution pipe. The bottoms of the first cooling water channel and the second cooling water channel are connected. The invention is used for transporting wood tar into the fluidized bed hydrogenation reactor.
Description
technical field [0001] The invention relates to components of a wood tar ebullating bed hydrogenation reactor, in particular to an oil inlet distribution pipe for the wood tar ebullating bed hydrogenation reactor. Background technique [0002] Biomass pyrolysis technology can convert biomass (such as woody raw materials, agricultural waste) into liquid biomass tar (wood tar), and the yield can reach 65w%-70w% (w% means weight percentage). Wood tar has a complex composition, high moisture content, high corrosiveness, low calorific value, and is unstable, easy to polycondensate, and difficult to miscible with petroleum products (such as gasoline, diesel, etc.). Since the end of the 1990s, countries around the world have successively carried out technical research on refining fuel oil from wood tar, among which wood tar ebullating bed hydrocracking is considered to be one of the technologies with the most development potential. Because wood tar will undergo severe coking under...
