Ma<strong>in</strong> scientific and technological achievements<br />

Dur<strong>in</strong>g the period 1986-1990, FC discovered the use <strong>of</strong> H-beta zeolite for the alkylation <strong>of</strong><br />

benzene with propylene, to synthesize cumene [1,2]; this process is currently employed by<br />

Polimeri Europa (ENI group) for the production <strong>of</strong> cumene. The advantages <strong>of</strong> the zeolite-based<br />

technology for benzene alkylation, as compared to the conventional process based on silicasupported<br />

phosphoric acid, are several: (a) a better selectivity to cumene, because <strong>of</strong> the steric<br />

limitations h<strong>in</strong>der<strong>in</strong>g the formation <strong>of</strong> polyalkylated by-products, and because <strong>of</strong> the higher activity<br />

<strong>in</strong> polyalkylated transalkylation; (b) a higher productivity, because <strong>of</strong> the stronger acidity <strong>of</strong> the<br />

zeolite; (c) much less environmental problems; not only the zeolite can be regenerated by<br />

treatment <strong>in</strong> air, but also shows unchanged activity for several years before regeneration is<br />

needed. Conversely, the formerly used catalyst could not be regenerated, and had to be disposed<br />

every one year at best; (d) no production <strong>of</strong> waste acid sludges, that are <strong>in</strong>stead typically produced<br />

with the formerly used catalyst, and are the reason for severe equipment corrosion and for<br />

environmental concerns because <strong>of</strong> its disposal.<br />

Dur<strong>in</strong>g the period 1997-2003, FC has developed <strong>in</strong> collaboration with Lonza SpA (formerly<br />

Alusuisse, later Polynt), a catalyst based on vanadyl pyrophosphate (VO)2P2O7 for the<br />

selective oxidation <strong>of</strong> n-butane <strong>in</strong>to maleic anhydride [3-5]. Along the years, the <strong>in</strong>dustrial<br />

catalyst, currently used <strong>in</strong> the Polynt plant <strong>in</strong> Ravenna produc<strong>in</strong>g 50,000 tons/year <strong>of</strong> maleic<br />

anhydride, and <strong>in</strong> other plants delivered to other companies and us<strong>in</strong>g Polynt catalyst, has been<br />

improved, both <strong>in</strong> terms <strong>of</strong> maleic anhydride yield, catalyst lifetime and stability dur<strong>in</strong>g operation. In<br />

concomitance with the development <strong>of</strong> the catalyst (with various generations <strong>of</strong> improved catalyst<br />

produced and used dur<strong>in</strong>g the years), the nature <strong>of</strong> the active phase <strong>in</strong> the vanadyl pyrophosphate<br />

catalyst has been ascerta<strong>in</strong>ed [6-9], that also allowed understand<strong>in</strong>g the dynamic effects <strong>in</strong>volv<strong>in</strong>g<br />

the change <strong>of</strong> the active phase characteristics <strong>in</strong> function <strong>of</strong> reaction conditions, and hence modify<br />

accord<strong>in</strong>gly the catalyst composition and preparation procedure. The fluid-bed technology used by<br />

Polynt for the synthesis <strong>of</strong> maleic anhydride from n-butane is one <strong>of</strong> the most, if not the most,<br />

efficient technology, comb<strong>in</strong><strong>in</strong>g high selectivity to the desired product with excellent economics<br />

because <strong>of</strong> the better heat recovery.<br />

Dur<strong>in</strong>g the period 2008-2011, FC has extensively studied the mechanism <strong>of</strong> a process which,<br />

although <strong>in</strong>dustrially applied s<strong>in</strong>ce several years, yet had not been understood. Specifically, the<br />

reaction is the gas-phase methylation <strong>of</strong> phenol with methanol, catalyzed by basic (doped<br />

MgO: General Electric technology) or redox (V/Fe/O: Asahi technology) oxides, a reaction<br />

occurr<strong>in</strong>g with high region- and chemo-selectivity. It was generally accepted that the mechanism <strong>of</strong><br />

the reaction is a direct electrophylic substitution by methanol on the activated phenolate molecule.<br />

Start<strong>in</strong>g from the evidence that such mechanism is not conv<strong>in</strong>c<strong>in</strong>g, we were able to demonstrate<br />

that <strong>in</strong>deed the reaction mechanism <strong>in</strong>volves formaldehyde as true electrophylic molecule, where<br />

the aldehyde is formed by means <strong>of</strong> dehydrogenation <strong>of</strong> methanol, a reaction which is accelerated<br />

by the basic materials used <strong>in</strong>dustrially [1-6]. The electrophylic attack leads to the formation <strong>of</strong><br />

salycilic alcohol as the reaction <strong>in</strong>termediate, which is f<strong>in</strong>ally transformed <strong>in</strong>to the methylated<br />

compound (o-cresol and then 2,6-xylenol) by means <strong>of</strong> MPV-type reaction with formaldehyde itself,<br />

which also acts as a reduc<strong>in</strong>g agent for the methylol moiety. In overall, the reaction <strong>in</strong>deed consists<br />

<strong>of</strong> several steps, which are carried out <strong>in</strong> rapid cascade. In this sense, the direct transformation <strong>of</strong><br />

phenol <strong>in</strong>to the correspond<strong>in</strong>g methylated compounds is emblematic <strong>of</strong> how the comb<strong>in</strong>ation <strong>of</strong><br />

various catalyst functionalities (both basic, required for the phenol activation, and dehydrogenat<strong>in</strong>g)<br />

allows the conduction <strong>of</strong> complex reactions with high selectivity (one-pot reactions).<br />

<strong>Scientific</strong> collaborations with French Scientists<br />

Dur<strong>in</strong>g his <strong>career</strong>, FC has established strong scientific relationships with French scientists, both<br />

from <strong>in</strong>dustrial companies and public research bodies, that led to several jo<strong>in</strong>t publications <strong>in</strong><br />

<strong>in</strong>ternational journals. Especially <strong>in</strong> the field <strong>of</strong> catalytic selective oxidation, collaborations<br />

established allowed the understand<strong>in</strong>g <strong>of</strong> the <strong>in</strong>teraction between catalysts and reactive substrates,<br />

for reactions such as the ammoxidation <strong>of</strong> propane to acrylonitrile, the oxidation <strong>of</strong> n-butane to<br />

maleic anhydride, the oxidative dehydrogenation <strong>of</strong> isobutyric acid and the selective oxidation <strong>of</strong><br />

isobutane to methacrylic acid, and the oxidative dehydrogenation <strong>of</strong> alkanes to alkenes.<br />
