| 20090253949 | Pretreatment of a phosphorus-modified zeolite catalyst for a toluene methylation process - This invention relates to a process for pretreating a zeolite catalyst, specifically a zeolite which has been modified with phosphorus. The catalyst may be used in a process for alkylation of aromatics, specifically toluene methylation. The pretreatment is first to contact the catalyst with the process reactants used in a process for alkylation of aromatics for at least two hours at conditions to produce an alkylated aromatic product and then with a gaseous stream containing oxygen at a temperature and for a time until there is no oxygen consumption. The zeolite may be a MFI zeolite. This pretreatment procedure for a phosphorus-modified zeolite catalyst produces a catalyst which has increased run time, i.e., decreased deactivation rate, compared to a fresh catalyst, even after successive regenerations. | 10-08-2009 |
| 20100249477 | Method of Rapid Methylation, Kit for Preparing PET Tracer and Method of Producing PET Tracer - It is intended to provide a method of rapid methylation of an aromatic compound or an alkenyl compound, which is capable of obtaining an aromatic compound or an alkenyl compound labeled with a methyl group or a fluoromethyl group under a mild condition rapidly in high yield using an organic boron compound whose toxicity is not so high as a substrate; a kit for preparing a PET tracer to be used in the same, and a method of producing a PET tracer using the same. In an aprotic polar solvent, methyl iodide or X—CH2F (wherein X is a functional group which can be easily released as an anion), an organic boron compound in which an aromatic ring or an alkenyl group is attached to boron are subjected to cross-coupling in the presence of a palladium(0) complex, a phosphine ligand, and a base. | 09-30-2010 |
| 20110144401 | Process of Making Alkylaromatics Using EMM-13 - This disclosure relates to a process for manufacturing a mono-alkylaromatic aromatic compound, said process comprising contacting a feedstock comprising an alkylatable aromatic compound and an alkylating agent under alkylation reaction conditions with a catalyst comprising EMM-13, wherein said EMM-13 is a molecular sieve comprising a framework of tetrahedral atoms bridged by oxygen atoms, the tetrahedral atom framework being defined by a unit cell with atomic coordinates in nanometers shown in Table 3. | 06-16-2011 |
| 20120046509 | Process of Making Alkylaromatics Using EMM-12 - This disclosure relates to a process for manufacturing a mono-alkylaromatic compound, said process comprising contacting a feedstock comprising an alkylatable aromatic compound and an alkylating agent under alkylation reaction conditions with a catalyst comprising EMM-12, wherein said EMM-12 is a molecular sieve having, in its as-synthesized form and in calcined form, an X-ray diffraction pattern including peaks having a d-spacing maximum in the range of 14.17 to 12.57 Angstroms, a d-spacing maximum in the range of 12.1 to 12.56 Angstroms, and non-discrete scattering between about 8.85 to 11.05 Angstroms or exhibit a valley in between the peaks having a d-spacing maximum in the range of 10.14 to 12.0 Angstroms and a d-spacing maximum in the range from 8.66 to 10.13 Angstroms with measured intensity corrected for background at the lowest point being not less than 50% of the point at the same XRD d-spacing on the line connecting maxima in the range of 10.14 to 12.0 Angstroms and in the range from 8.66 to 10.13 Angstroms. | 02-23-2012 |
| 20160060187 | Treatment of Off-Gas in the Production of Para-Xylene by the Methylation of Toluene and/or Benzene - A process for removing contaminants from an off-gas stream generated by the methylation of toluene and/or benzene by methanol to produce para-xylene. The treated off-gas stream, which contains C | 03-03-2016 |
| 20160115103 | Method of Making Aromatic Hydrocarbons - A method for the purification of an aromatic hydrocarbon process stream having phenol therein is disclosed. Aspects of the method include contacting at least a portion of the aromatic hydrocarbon process stream with a hydrogenation catalyst under hydrogenation conditions to provide a hydrogenation effluent having a lower concentration of phenol than said aromatic hydrocarbon process stream. | 04-28-2016 |
| 20160160133 | ETHANOL TO FUELS IN A CATALYTIC CRACKING UNIT STRIPPER - Processes relating to the conversion of ethanol in a stripper unit of a fluidized catalytic cracking system. An ethanol stream mixes with a catalyst in the stripper unit under conditions of temperature that favor conversion of the ethanol to hydrocarbons, thereby increasing incorporation of ethanol into liquid transportation fuels without exceeding regulatory limits on fuel vapor pressure. Certain embodiments combine the ethanol stream with a hydrocarbon stream and react in the presence of a catalyst in a stripper to produce hydrocarbons that may have an increased boiling point, increased octane rating, decreased vapor pressure, decreased benzene content, or combinations thereof. | 06-09-2016 |
