Abstract—Effect of the preparation conditions of aluminum oxide on its catalytic activity and stability in the
course of vapor-phase dehydration of glycerol to give acrolein was studied. The conditions were determined in
is prepared so that the maximum selectivity of acrolein formation (~60%) and glycerol conversion
(~80%) is in 10 h. The results of the study suggest that systems based on γ-Al
are the most promising catalysts
for the process under consideration.
Acrolein is a raw material for obtaining a wide vari-
ety of valuable products. The main purpose of acrolein
processing is to obtain acrylic acid used in manufacture
of superabsorbents, acryl emulsions in paint-and-varnish
industry, drilling reagents, polyacrylonitrile ﬁ bers and
acrylate caoutchoucs, and building mixtures and glues.
Acrolein and its derivatives are used in manufacture of
1,3-propanediol, pyridine, and glutaric aldehyde. It is also
used as raw material for production of medicinal prepara-
tions, herbicides, ﬂ avoring agents, and plasticizers.
At present, the main industrial method for obtaining
acrolein is the partial oxidation of propylene [1–4]. This
method has a number of important shortcomings the
main of which are the following: high cost of propylene
obtained in cracking and pyrolysis of oil hydrocarbons;
poor ecological safety of the production process because
of the use of petrochemical raw materials and formation
of carbon oxides; difﬁ cult isolation and puriﬁ cation of
the commercial product due to the formation of a large
amount of by-products (acetic acid, acetaldehyde, maleic
In addition, about, on average, 54% of propylene sold
in 2008–2012 was expended for production of polypro-
pylene. In the near future, the fraction of propylene used
to manufacture polypropylene will be growing. According
to the estimate by BusinesStat, the fraction of propyl-
ene to be processed into polypropylene will be 75% in
2017. Other propylene-consuming industries will also
be actively developing. In the market experts’ opinion,
manufacturers of polyurethanes will add in the near future
will add to the number of propylene consumers.
Thus, in the present-day conditions of the shrinking
resources of fossil fuel-energy resources, increase in their
cost, and increasingly stringent ecological requirements,
the research works aimed to use renewable vegetable raw
materials for obtaining valuable chemical products have
drastically intensiﬁ ed.
One of promising ways to solve this problem is to ob-
tain acrolein from glycerol, the excess of amount of which
has been formed in recent years in the world market due
to the sharp rise in the manufactured amounts of biodiesel
fuel [5–10]. According to experts’ estimates , if the
tendency toward increasing cost of oil products is pre-
served, this technique will become strongly competitive
with the conventional propylene-based method due to the
use of potentially less expensive renewable natural raw
materials and to the higher ecological safety of the former.
At present, it is suggested to perform the dehydration
of glycerol in the vapor or liquid phase in the presence of
solid-phase catalysts of the acid type: zeolites, supported
