Abstract: A method of increasing the selective desulfurization of naphtha feed streams that includes: combining a naphtha feed stream with a hydrogen containing gas to form a combined feed stream and reacting the combined feed stream over a monolithic honeycomb catalyst bed containing hydrodesulfurization catalyst components to give a desulfurized naphtha. In conducting such an illustrative embodiment, the percent desulfurization of the naphtha is preferably greater than about 50% and the percent olefin hydrogenation of the naphtha is preferably less than about 50%. The monolithic honeycomb catalyst bed of one alternative and illustrative embodiment preferably has a channel density of about 25 to 1600 cells per square inch; a channel size from about 0.1 to 10 mm; and a channel wall thickness of about 0.01 to about 2.0 mm. The illustrative method should be carried out such that the octane number (R+M/2) of the naphtha feed stream is reduced by no more than 3.0 at 95% desulfurization and preferably no more than 1.5. The hydrodesulfurization catalyst components include a powdered refractory oxide and transition metal catalyst compounds. Alternatively the hydrodesulfurization catalyst components may be impregnated into the monolithic honeycomb catalyst bed itself. Preferable hydrodesulfurization catalyst components include a Group VIII metal containing compound and a Group VIB metal containing compound. Alternatively the hydrodesulfurization catalyst components may further include a phosphorous promoter.

Abstract: This invention is a projector headlight that, while offering dual beam patterns, boasts a 100% utilization of the light emitted from a light source by one of the following methods: (1) employing a reflective cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern, (2) using reversible cutoff shield means to reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern with no moving part involved, (3) utilizing a selective light-filter cutoff means to selectively reflect the incoming light from said light source back to the reflector to enhance the illumination in low-beam pattern without making use of any moving part, (4) using a low-beam light-emitting subassembly and a high-beam light-emitting subassembly that are separated by partition means to achieve dual beam patterns with no moving part, or (5) adopting a low-beam light-emitting subassembly in low-beam pattern and a high-beam light-emitting subassembly in high-beam pattern without any moving part.
