    摘要: A catalyst suitable for gasoline reforming has 0.01-5% wt of a Pt group metal and 0.01-5% wt of uranium on a silica-free alumina having a surface area of at least 150 m2 /g. Alkali metals, alkaline earth metals and Group VI A metals (other than U) are absent, but 0.01-5% wt of rhenium may also be present as may 0.01-5% wt of chlorine. Reforming using such catalysts is also claimed at 300*-600*C, 1-70 bars gauge, 0.01-10 v/v/hr and 0.0120:1 hydrogen: hydrogen mole ratio. The presence of uranium improves catalyst activity and stability to deactivation.

    摘要: A burner for fluid fuels comprises a fuel chamber, a plurality of combustion air tubes which pass through the fuel chamber and a packing positioned between the combustion air tubes and adjacent to the combustion zone. The packing divides the fuel chamber into an unpacked inlet zone into which the fuel first passes and a packed outlet zone through which the fuel passes on its way to the combustion zone. For gaseous fuels the packing is a high outlet resistance so that even fuel distribution is achieved in the unpacked zone. For liquid fuels the packing acts as a wick and assists in heat transfer to vaporise the fuel into the combustion zone.

    摘要: Treatment of a micro-organism containing material in which there is present an evaporable material and water, said water being present in an amount greater than 20% based on the dry weight of the micro-organism, the micro-organism being treated to remove part or the whole of the evaporable material while maintaining at least 20% of water, based on the dry weight of the microorganism, in association with said micro-organism. Optionally, water may first be removed to reduce the water content to at least 20%. Optionally further water may be removed after the evaporable material has been removed. The micro-organism containing material may be obtained by solvent extraction of a micro-organism which has been grown on a hydrocarbon substrate.

    摘要: A quench box suitable for use in a down flow reactor has walls defining an inner and an outer compartment, passages in the outer-compartment wall, a contoured roof giving a valley with passages into the inner compartment, and passages in the floor of the outer compartment. Preferred ratios of the areas of the three sets of passages are given and preferred ratios of dimensions for the box. The box is particularly suitable for reactors for the hydrocatalytic treatment of petroleum fractions boiling above 300*C and a hydrogen injection ring may be placed above the quench box.

    摘要: A bituminous composition is prepared by blending bitumen, an aromatic flux oil and an E P T rubber latex and blowing the mixture. The resulting composition is homogeneous and even when stored hot, little or no separation of the components take place. It is particularly suitable for use as a roofing or sealing material.

    摘要: Air or gas ground graphite is formed into pellets by mixing with finely divided alumina, forming into a paste and then granulating or extruding. The pellets so formed can be used as air or gas ground graphite but with the advantage that the pellets can be in the form of a fixed bed. A typical application is a polishing treatment for lubricating oils to remove aromatics, heterocyclics, sulphur compounds and coloured materials.

    摘要: In a concrete coated pipeline, the concrete coating is discontinuous, the maximum length of any section of coating being 12 feet and the gap between adjacent coatings (which can be filled with bitumen) at least one-sixteenth inch. Preferably the length is from 2 to 8 feet and the thickness of the coating 2 to 3 inches. The advantage of the structure is that breaking of the coating when laying the pipeline is reduced.
