摘要： Petroleum waxes are converted to high viscosity index lubricants by a hydroisomerization process in which the wax feed is subjected to hydroisomerization over a low acidity molecular sieve isomerization catalyst (the molecular sieve being preferably a zeolite) which effects a preferential isomerization on the paraffin components in the feed to less waxy, high VI isoparaffins. The hydroisomerization is operated at high pressure, at least 1000 psig hydrogen partial pressure (reactor inlet) using a zeolite catalyst, preferably a noble metal containing zeolite beta catalyst which contains boron as a framework component of the zeolite to give a low alpha value, typically below 10. The hydroisomerization is carried out at with a 650° F.+ conversion in the range of 10 to 40 weight percent of the feed. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have VI values in excess of 125 and usually in the range of 130 to and are characterized by exceptional stability.

摘要： Petroleum wax feeds are converted to high Viscosity Index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to non-lube range products of no more than about 30 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 1000 psig using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity dicarboxylic acid-treated zeolite Beta or mordenite catalyst which effects a preferential isomerization on the paraffin components to less waxy, high V.I. isoparaffins. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite Beta catalyst which is treated with oxalic acid to give a low Alpha Value, typically below 10. The second stage is carried out at relatively low temperature, typically from 600.degree. to 650.degree. F. with a 650.degree. F.+ conversion in the range of 10 to 20 weight percent of the second stage feed but with high selectivity for isomerization of the paraffins. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have V.I. values in excess of 130 and usually in the range of 140 to 155 and are characterized by exceptional stability.

摘要： Petroleum wax feeds having a low oil content are converted to high viscosity index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to lube range products of between generally 30 and 40 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 800 psig using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity zeolite beta catalyst. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite beta catalyst. The second stage is carried out at relatively low temperature, typically from 600.degree. to 650.degree. F.

摘要： Petroleum wax feeds are converted to high viscosity index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed which exhibits branchingis initially subjected to hydrocracking under mild conditions with a conversion to non-lube range products of no more than about 30 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 1000 psig (7000 kPa) using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity zeolite beta catalyst which effects a preferential isomerization on the paraffin components to less waxy, high VI isoparaffins. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite beta catalyst which contains boron as a framework component of the zeolite to give a low alpha value, typically below 10 while maintaining an isomerizaiton selectiveity of no less than 48%. The second stage is carried out at relatively low temperature, typically from 600° to 650° F. with a 650° F.+ conversion in the range of 10 to 20 weight percent of the second stage feed but with high selectivity for isomerization of the paraffins. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have VI values in excess of 140 and usually in the range of 143 to 147 and are characterized by exceptional stability.

摘要： Akylation product is contacted with a purification medium in a liquid phase pre-reaction step to remove impurities and form a purified stream. The purified stream may then be further processed by liquid phase transalkylation to convert the polyalkylated aromatic compound to a monoalkylated aromatic compound. The process may use a large pore molecular sieve catalyst such as MCM-22 as the purification medium in the pre-reaction step because of its high reactivity for alkylation, strong retention of catalyst poisons and low reactivity for oligomerization under the pre-reactor conditions. Olefins, diolefins, styrene, oxygenated organic compounds, sulfur containing compounds, nitrogen containing compounds and oligomeric compounds are removed.
