摘要： A process for producing a diene, preferably a conjugated diene, more preferably 1,3-butadiene, includes the steps of dehydrating at least one alkenol in the presence of at least one catalytic material having at least one acid catalyst based on silica (SiO2) and alumina (Al2O3), preferably a silica-alumina (SiO2—Al2O3), the catalyst having an alumina content (Al2O3) lower than or equal to 12% by weight, preferably between 0.1% by weight and 10% by weight, with respect to the catalyst total weight. The alumina content is referred to the catalyst total weight without binder, and a pore modal diameter between 9 nm and 170 nm, preferably between 10 nm and 150 nm, still more preferably between 12 nm and 120 nm. Preferably, the alkenol is obtainable directly from biosynthetic processes, or catalytic dehydration processes of at least one diol, preferably a butanediol, more preferably 1,3-butanediol, still more preferably bio-1,3-butanediol, deriving from biosynthetic processes.

摘要： The present invention relates to a process for producing a diene, preferably a conjugated diene, more preferably 1,3-butadiene, comprising the dehydration of at least one alkenol having a number of carbon atoms greater than or equal to 4, in the presence of a catalytic material comprising at least one crystalline metalosilicate in acid form, preferably a macroporous zeolite, more preferably a zeolite with a FAU, BEA or MTW structure. Preferably, said alkenol having a number of carbon atoms greater than or equal to 4 may be obbtained directly through biosynthetic processes, or through catalytic dehydration processes of at least one diol. When said alkenol is a butenol, said diol is preferably a butanediol, more preferably 1,3-butanediol, even more preferably bio-1,3-butanediol, i.e. 1,3-butanediol deriving from biosynthetic processes. When said alkenol is 1,3-butanediol, or bio-1,3-butanediol, the diene obtained with the process according to the present invention is, respectively, 1,3-butadiene, or bio-1,3-butadiene.

摘要： It is disclosed a process for propagating a yeast capable to ferment glucose and xylose of a lignocellulosic feedstock hydrolyzate, said process comprising propagating the yeast over at least two propagation cycles. The first propagation cycle comprises the steps of: contacting the yeast at a starting yeast density with a first cultivation medium comprising a first portion of the lignocellulosic feedstock hydrolyzate; and allowing the yeast to propagate to create a first populated broth comprising water and a first propagated yeast, wherein at least 50% of the glucose and less than 20% of the xylose in the first cultivation medium are consumed in the first propagation cycle. The second cycle comprises the steps of: separating the first populated broth in at least a first removed portion and a first residual portion, wherein both the first residual portion and the first removed portion comprise some of the first propagated yeast; contacting the first residual portion with a second cultivation medium comprising a second portion of the lignocellulosic feedstock hydrolyzate; and allowing the yeast to propagate to create a second populated broth comprising water and a second propagated yeast, wherein at least 50% of the glucose and less than 20% of the xylose in the second cultivation medium are consumed in the second propagation cycle.
