摘要:
A smoke emissivity test includes the steps of burning a relatively small sample of fuel (32) on a grate (2) for a set time and collecting the 'smoke' on a preweighed filter (20). At the conclusion of the test the filter is reweighed and the emissivity calculated as a percentage on a w/w basis.
摘要:
A coal is impregnated with 0.01 to 1% by weight of molybdenum disulphide and hydropyrolysed. The products are catalytically hydrocracked. Large yields of valuable liquid products are obtained under moderate conditions, and there is a relatively low production of gas.

A filter press cloth hanger has two arms (1, 2) joined by a hinge (3) at their top ends. Each arm has a spring loaded rod (7) which carries a latching device (8, 9) for a suspension member for a filter cloth.

摘要:
Relative angular movement between two linear members is detected by shining light from a light source (11) through a triangular mask (12) in one member onto a mirror (10) in the other member and reflecting the image of the triangular mask onto a linear array of detectors (15). Movement between the two members causes different detectors in the array to be illuminated and the position and number of detectors illuminated determines the X and Y axis of movement to enable the relative angular movement of the two members to be calculated.
摘要:
A cold coal briquetting process comprises mixing fine coal with polyvinyl alcohol and a hardening agent selected from iron oxide, phosphate rock and bauxite or combination of two or more thereof. The process permits economies in process and capital costs compared to existing briqueting processes, while still producing satisfactory briquettes.
摘要:
A mixture of C10 to C14 aromatic hydrocarbons, e.g., resulting from a synthesis reaction, is upgraded to lower alkyl benzenes by passing the mixture over an aluminosilicate catalyst together with a catalytic additive, which can be recovered for re-use. At least an equivalent weight of catalytic additive is used and the upgrading is carried out in the vapour phase.

An inproved cyclone separator (1) comprises a body (2) defining a main vortex chamber (6) having an inlet (4) and a fluid outlet (8). A secondary vortex chamber (14) communicates with and opens into the main vortex chamber (6).
摘要:
A catalyst having stability in air, exhibiting long life and capable of use in the conversion of synthesis gas to hydrocarbons, consists of particles of a disordered residue intercalate having a catalytic substance derived from the guest substance on the outer surfaces of the particles. The disordered residue intercalate retains about 1-10% of guest substance, modifying its electronic properties.
