Of particular benefit of the present processes is the selective treating of cat naphthas to remove gums instead of undercutting the overall... http://www.freshpatents.com/-dt20130516ptan20130118953.php Mon, 20 May 2013 13:33:21 -0700 Disclosed is a process for hydrotreating inferior naphtha fraction, comprising: (1) warming a recycle oil in a heating device; (2) mixing the inferior naphtha fraction with the recycle oil before and/or after the heating device; and (3) feeding the mixture of the inferior naphtha fraction and the recycle oil into... http://www.freshpatents.com/-dt20130516ptan20130118954.php Mon, 20 May 2013 13:33:21 -0700 This invention relates to the composition, method of making and use of a hydrocracking catalyst that is comprised of a new Y zeolite which exhibits an exceptionally low small mesoporous peak around the 40 Å (angstrom) range as determined by nitrogen adsorption measurements. The hydrocracking catalysts of invention exhibit improved... http://www.freshpatents.com/-dt20130516ptan20130118955.php Mon, 20 May 2013 13:33:21 -0700 The present invention relates to an improved desulfurization process using an ionic liquid compound of general formula C+A−, where C+ represents an organic cation such as alkyl-pyridinium, di-alkyl imidazolium and tri-alkyl imidazolium; and A− is an anion of halides of iron (III), such as, for example, FeCl4−. The desulfurization process...
