A cikin 1931, Adskins masanin kimiyar Amurka ya gane hydrogenation na furfural zuwa barasa na farko tare da jan karfe chromic acid a matsayin mai kara kuzari, kuma ya gano cewa samfurin ya kasance mafi yawan samfuran zurfin hydrogenation na zoben furfuran da aldehyde, da zaɓin samfurin za a iya inganta ta hanyar canza yanayin zafi da yanayin dauki. Dangane da yanayi daban-daban na amsawa, ana iya raba tsarin furfural hydrogenation zuwa barasa na furfuryl zuwa hanyar lokaci na ruwa da tsarin tsarin gas, wanda za'a iya raba shi zuwa hanyar matsin lamba (9.8MPa) da hanyar matsa lamba (5 ~ 8MPa).

ruwa lokaci hydrogenation

Ruwa lokaci hydrogenation shi ne ya dakatar da mai kara kuzari a furfural a 180 ~ 210 ℃, matsakaici matsa lamba ko high matsa lamba hydrogenation, na'urar ne fanko hasumiya reactor. Don rage nauyin zafi, ana sarrafa ƙarin adadin furfural sau da yawa kuma an tsawaita lokacin amsawa (fiye da 1h). Saboda da backmixing na kayan, hydrogenation dauki ba zai iya zama a cikin mataki na furfuryl barasa tsara, kuma zai iya kara samar da byproducts kamar 22 methylfurfuran da tetrahydrofurfuran barasa, wanda take kaiwa zuwa high albarkatun kasa amfani, da wuya a dawo da sharar kara kuzari, da sauki ga. haifar da mummunar gurbataccen chromium. Bugu da ƙari, ana buƙatar yin aiki da hanyar lokaci na ruwa a ƙarƙashin matsin lamba, wanda ke buƙatar buƙatun kayan aiki mafi girma. A halin yanzu, ana amfani da wannan hanya a kasarmu. Babban matsin lamba shine babban gazawar hanyar ruwa-lokaci. Duk da haka, an ba da rahoton samar da barasa na furfuryl ta hanyar amsawar ruwa-lokaci a ƙarƙashin ƙananan matsa lamba (1 ~ 1.3MPa) a kasar Sin, kuma an sami yawan amfanin ƙasa.

A matsayin daya daga cikin albarkatun kasa don hada kwayoyin halitta, ana iya amfani da shi don samar da levulin acid, resin furan mai dauke da kadarori daban-daban, furfuryl barasa-urea guduro da phenolic resin.
