| 20100294470 | Tube Sheet Assembly - Disclosed is a tube sheet assembly for a waste heat boiler employed in a chemical process plant and which makes use of metal ferrules for protecting the inlets of the exchange tubes of the tube sheet. The tube sheet assembly includes at least one thermal insulator which is located inside an inlet opening of a tube sheet of the tube sheet assembly, and which covers a portion of a respective ferrule of the tube sheet assembly, thereby providing thermal insulation between the tube sheet and the ferrule. | 11-25-2010 |
| 20100210737 | SYNTHETICALLY DERIVED ILLUMINATING AND HEATING PARAFFIN OIL - The invention provides synthetically derived distillate kerosene produced by catalytic conversion of Fisher-Tropsch derived light olefins to distillates (COD) and hydrotreating thereof. The kerosene boils in the range of about 170 to 250° C. and includes less than 10% n-paraffins, more than 75% iso-paraffins and less than 1% aromatics. | 08-19-2010 |
| 20090294329 | PROCESS FOR CATALYTIC CONVERSION OF FISCHER-TROPSCH DERIVED OLEFINS TO DISTILLATES - The invention provides a low aromatic producing process for catalytical conversion of Fisher-Tropsch derived olefins to distillates (COD), which process includes the step of contacting Fisher-Tropsch derived olefins with a zeolyte type catalyst at pressures of more than 50 barg. | 12-03-2009 |
| 20080257783 | Process for Catalytic Conversion of Fischer-Tropsch Derived Olefins to Distillates - The invention provides a low aromatic producing process for catalytical conversion of Fisher-Tropsch derived olefins to distillates (COD), which process includes the step of contacting Fisher-Tropsch derived olefins with a zeolyte type catalyst at pressures of more than 50 barg. | 10-23-2008 |
| 20080250704 | Synthetically Derived Illuminating and Heating Paraffin Oil - The invention provides synthetically derived distillate kerosene produced by catalytic conversion of Fisher-Tropsch derived light olefins to distillates (COD) and hydrotreating thereof. The kerosene boils in the range of about 170 to 250° C. and includes less than 10% n-paraffins, more than 75% iso-paraffins and less than 1% aromatics. | 10-16-2008 |
| 20080250699 | Production of Near Zero Aromatics Containing Diesels - The invention provides a process for the production of synthetically derived diesel and diesel produced by the process. The process includes the steps of catalytic conversion of Fisher-Tropsch derived light olefins to distillates (COD) over a zeolite type catalyst at pressures of more than 50 barg, one step hydrotreating the COD product to simultaneously hydrogenate both olefins and aromatics, and collecting a hydrotreated fraction boiling between about 180° C. to 360° C. | 10-16-2008 |
