A process for preparing a naphtha reforming catalyst has been developed. The process involves the use of a chelating ligand such as ethylenediaminetetraacetic acid (EDTA). The aqueous solution of the chelating ligand and a tin compound is used to impregnate a support, e.g., alumina extrudates. A platinum-group metal is also an essential component of the catalyst. Rhenium may also be a component. A reforming process using the catalyst has enhanced yield, activity, and stability for conversion of naphtha into valuable gasoline and aromatic products.

A catalyst for selectively opening cyclic paraffins has been developed. The catalyst comprises a Group VIII metal, such as platinum, a modifier component, such as niobium or ytterbium, a molecular sieve, such as UZM-16 and a refractory inorganic oxide such as alumina. The Group VIII metal and modifier component are preferably deposited on the refractory inorganic oxide. A process for using the catalyst is also disclosed.

Dual functional catalyst for selective opening of cyclic paraffins and process for using the catalyst

A process is disclosed for regenerating a hydrocarbon conversion catalyst comprising zeolite L with ozone. The catalyst is contacted with ozone at a temperature of from about 20 to about 250&#xb0; C. and a concentration of ozone of from about 0.1 to about 5 mol-%. The catalyst may contain coke. The process at least partially restores the activity of the catalyst. The process is particularly useful for reforming and dehydrocyclodimerization catalysts.

A process for producing phenyl-alkanes by paraffin dehydrogenation followed by olefin isomerization and then by alkylation of a phenyl compound by a lightly branched olefin is disclosed. An effluent of the alkylation section comprises paraffins that are recycled to the dehydrogenation step. A process that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups to produce modified alkylbenzene sulfonates is also disclosed. In addition, the compositions produced by these processes, which can comprise detergents, lubricants, and lubricant additives, are disclosed.

Long chain alcohols and acids or other similar oxygenates such as esters are produced from paraffins of similar carbon number by a process comprising paraffin dehydrogenation, carbonylation, and separation. Preferably a mixture of paraffins extending over several carbon numbers and recovered from a kerosene fraction is processed, and unconverted paraffins are recycled to a dehydrogenation zone. Alternative reaction zone configurations, catalyst systems and product recovery methods are disclosed.

Carbonylation process

The present invention is a process for producing aryl-alkanes by paraffin isomerization followed by paraffin dehydrogenation and then by alkylation of an aryl compound by a lightly branched olefin. The effluent of the alkylation zone comprises paraffins that are recycled to the isomerization step or to the dehydrogenation step. This invention is also a process that that sulfonates phenyl-alkanes having lightly branched aliphatic alkyl groups that to produce modified alkylbenzene sulfonates. In addition, this invention is the compositions produced by these processes, which can be used as detergents having improved cleaning effectiveness in hard and/or cold water while also having biodegradability comparable to that of linear alkylbenzene sulfonates, as lubricants, and as lubricant additives. This invention is moreover the use of compositions produced by these processes as lubricants and lubricant additives.

A novel integrated system for the co-production of heat and electricity for residences or commercial buildings is based on the cracking of hydrocarbons to generate hydrogen for a fuel cell. Compared to prior art reforming methods for hydrogen production, the cracking reaction provides an input stream to the fuel cell that is essentially free of CO, a known poison to the anode catalyst in many fuel cell designs, such as PEM fuel cells. The cracking reaction is coupled with an air or steam regeneration cycle to reactivate that cracking catalyst for further use. This regeneration can provide a valuable source of heat or furnace fuel to the system. A novel control method for system adjusts the durations of the cracking and regeneration cycles to optimize the recovery of reaction heat.

Process for producing arylalkanes and arylalkane sulfonates, compositions produced therefrom, and uses thereof

An improved process is disclosed for the selective disproportionation and transalkylation of toluene. The process uses a zeolitic catalyst, preferably comprising a binder, containing a weak metal in a defined reduced state which is believed to provide Lewis acidity in the catalyst. The catalyst and process provide improved selectivity for the production of paraxylene.

Hydrocarbon conversion processes are described which use a sulfur tolerant catalyst system. The catalyst is tolerant to large amounts (about 30,000 ppm sulfur) in the feedstream and comprises a first component which comprises at least one Group VIII metal dispersed on an inorganic oxide support and a second component comprising a metal phthalocyanine dispersed on an inorganic oxide support. Preferred Group VIII metals are platinum and palladium, while preferred metal phthalocyanines are cobalt or nickel phthalocyanine. Preferred inorganic oxide supports are molecular sieves, aluminas and mixtures thereof. Processes which can be carried out using this catalyst system include reforming, hydrocracking, dehydrogenation and isomerization.

A paraffin isomerization process is described and claimed. The process involves contacting the paraffins with an isomerization catalyst at isomerization conditions. Additionally, the process requires the injection of a nitrogen containing compound such as an amine, e.g., t-butylamine, and raising the operating temperature by about 20.degree. C. to about 150.degree. C. The effect of these modifications is to provide improved selectivity and sulfur resistance to the catalyst.
