Abstract: A process for bio-1,3-butanediol purification from a fermentation broth includes the steps of: (a) subjecting the fermentation broth to separation, (b) subjecting the product obtained in step (a) to treatment with ion-exchange resins, (c) subjecting the product obtained in step (b) to a first evaporation, (d) subjecting the product obtained in step (c) to a second evaporation; and (e) subjecting the product obtained in step (d) to a third evaporation, obtaining purified bio-1,3-butanediol. The purified bio-1,3-butanediol can be used to produce bio-1,3-butadiene. Bio-1,3-butadiene can be used as a monomer or as an intermediate to produce elastomers and (co)polymers.

Abstract: Control methods are disclosed for continuous, unmodulated, multiple catalytic conversion step processes using at least two catalysts, a first catalyst and a second catalyst, that accommodate changes in the performance of each catalyst and the relative performances of the catalysts. In the methods, certain process parameters are used in a manner that is indicative of changes in catalyst performance, and the control methods provide for adjustment of at least one of: the absolute amount of catalytically active species and relative amounts of each of the first catalyst and second catalyst and at least one of the rate of feed or concentration of the raw material to the reaction zone.

Abstract: A Ni—Al2O3@Al2O3—SiO2 catalyst with coated structure is provided. The catalyst has a specific surface area of 98 m2/g to 245 m2/g, and a pore volume of 0.25 cm3/g to 1.1 cm3/g. A mass ratio of an Al2O3 carrier to active component Ni in the catalyst is Al2O3:Ni=100:4˜26, a mass ratio of the Al2O3 carrier to an Al2O3—SiO2 coating layer is Al2O3:Al2O3—SiO2=100:0.1˜3, and a molar ratio of Al to Si in the Al2O3—SiO2 coating layer is 0.01 to 1. Ni particles are distributed on a surface of the Al2O3 carrier in an amorphous or highly dispersed state and have a grain size less than or equal to 8 nm, and the coating layer is filled among the Ni particles.
