摘要： The design and control of a process to produce furfuryl alcohol is reported. Furfural is hydrogenated to furfuryl alcohol in a gas phase packed bed reactor with high selectivity and conversion. The product alcohol is separated from unreacted furfural and byproducts water and 2-methyl furan in a single low-pressure distillation column. Catalyst dilution is employed to increase the area available for heat transfer in the reactor. Control studies indicate that single-point temperature control of the distillation column is adequate to maintain product purity and avoid excessive loss of valuable material from the top of the column. A reactor effluent composition controller cascaded onto a reactor temperature controller can compensate for catalyst deactivation by raising the reactor temperature. •A process to produce furfural alcohol is developed.•Reaction occurs in the gas phase.•A single distillation column can produce high-purity product.•A proposed control structure can effectively reject disturbances. 出版者： Elsevier B.V 出版日期： 2015-06 出處： Journal of the Taiwan Institute of Chemical Engineers, 2015-06, Vol.51, p.44-52 資源來源： Elsevier ScienceDirect Journals Complete - Autoholdings 版權： 2015 Taiwan Institute of Chemical Engineers 識別號： ISSN: 1876-1070 識別號： EISSN: 1876-1089 識別號： DOI: 10.1016/j.jtice.2015.01.001
