A rapid infrared spectrophotometric metrod for determining furfural content in the raffinate of fur fural extraction of FCC light cycle oil is established.
In this paper, the PVA of major component in the Sensitized emulsion was modified by the polyreaction with formaldehyde, butyl aldehyde, furfural and alcohol.
The oils were analyzed by GC-MS and percentages were obtained by normalized peak areas, where main components are nootkatone, D-limonene, osthole, cis-linaloloxide, furfural, and trans.
The artical detailedly reviews the adhibition of three both series hydrolyze technics in the furfural production and the merit of economize energy resources and increase production.
It exists the option of an alkaline or a neutral cooking to produce bleachable paper pulp, and of acid hydrolysis of the straw to produce furfural and fermentable pentoses to produce methanol.
