“…The non-aromatic gasoline fuel is made by alkylation, in which the lighter hydrocarbons are combined to form longer high-octane-rate gasoline using a catalyst. 78 The alkylate components in the non-aromatic gasoline also have high-octane numbers. 79 HVO is manufactured from renewable and sustained sources of fats and oils, resulting in diesel fuel free from oxygen, sulphur, and aromatic compounds.…”

“…Meanwhile, it is of utmost priority to ensure the production of high quality fuels by upgrading processes such as the production of alkylate gasoline, present in many refineries since the 1930s . Isobutane/butene alkylation was established as an auxiliary fuel production process due to the need for high octane aviation fuel, where the main catalyst was H 2 SO 4 , and some years later, HF was also implemented. , Nowadays, both acids are still being used with a relatively same alkylate volume production every year, and just in recent days, alternative processes using solid catalysts have emerged, such as the alkyClean (ABB Lummus), Lurgi Eurofuel, or UOP’s alkylene as well as Haldor–Topsoe’s FBA process. Their main drawback is the rapid deactivation of the catalyst .…”

The application of methanesulfonic acid (MSA) as a green catalyst for the production of alkylate gasoline was successfully attained in the liquid (batch pressure reactor) and gas phase (1 atm, glass reactor, with MSA supported on silica gel) using real refinery hydrocarbon mixtures containing isobutane and butenes. The product quality was monitored by gas and liquid chromatography, yielding octane (C8s) selectivity of up to 92% in the gas phase and 70% in the liquid phase. The reaction temperature and catalyst/hydrocarbon mass ratio were the most influential reaction parameters affecting the conversion and selectivity. The addition of a liquid co-catalyst to MSA negatively affects the quality of the alkylate product, as well as the conversion of butenes. The presence of the silica support, in the gas phase at continuous regime alkylations, allowed us to obtain alkylate gasoline with sustained high conversions and selectivity to C8s at a quality similar or even higher to that obtained with sulfuric acid as the commercial catalyst. Characterization of the supported MSA reveals strong dipole–dipole interactions, revealed through the protonation of the surface –OH groups.

A molecular kinetic model incorporating catalyst acidity for hydrocarbon catalytic cracking

This work built a molecular-level kinetic model for hydrocarbon catalytic cracking, incorporating the catalyst acidity as the parameter to estimate reaction rates. The ndecane and 1-hexene co-conversion catalytic cracking process was chosen as the studying case. The molecular reaction network was automatically generated using a computer-aided algorithm. A modified linear free energy relationship was proposed to estimate the activation energy in a complex reaction system. The kinetic parameters were initially regressed from the experimental data under several reaction conditions. On this basis, the product composition was evaluated for three catalytic cracking catalysts with different Si/Al. The Bronsted acid and Lewis acid as the key catalyst properties were correlated with kinetic parameters. The built model can calculate the product distribution, gasoline composition, and molecular distribution at different reaction conditions for different catalysts. This sensitive study shows that it will facilitate the model-based optimization of catalysts and reaction conditions according to product demands.
