摘要:
A dispensing device (100) comprising at least one pair of indicia (235, 450) on separate structures (230, 400) which are rotatable with respect to one another, wherein the indicia have corresponding shapes such that alignment or unalignment of the corresponding shapes puts the device in a locked or unlocked position.

A fuel composition for a spark-ignition internal combustion engine comprises a non-metallic octane-boosting additive. The non-metallic octane-boosting additive is an additive which, when used at a treat rate of 0.67 % by weight, increases the research octane number of a fuel by at least 1.8 whilst maintaining the T 90 and/or the vapour pressure.
摘要:
A method for preparing a fuel composition which comprises a base fuel, an oxygenate and an octane-boosting additive comprises: blending an additised oxygenate with a base fuel, wherein the additised oxygenate comprises an oxygenate and an octane-boosting additive. The method enables suitable amounts of octane-boosting additives to be incorporated into a fuel composition, whilst enabling fuels having a range of properties to be prepared.
摘要:
The use as an intake valve deposit clean-up additive in a fuel composition for a port fuel injection spark-ignition internal combustion engine or a fuel injector deposit clean-up additive in a fuel composition for a direct injection spark-ignition internal combustion engine of a combination of: a. at least one hydrocarbyl-substituted aromatic compound; and b. at least one polyalkylene amine.
摘要:
A process for recovering heat uses a product stream from a Fischer Tropsch synthesis reactor as the coolant in the same Fischer Tropsch reactor. This stream is then used as the working fluid in an associated organic Rankine cycle. In this manner, the waste heat from the Fischer Tropsch reactor can be efficiently converted into shaft work within the Fischer Tropsch plant. The Fischer Tropsch fluid can then be recycled into the plant product stream.
摘要:
An aerosol shave composition, preferably a post foaming shave gel, comprising a hydrophobic agent, such as a silicone, in the form of a microdroplet having a particle size from about 0.15 microns to about 10 microns.
