摘要： The invention concerns a method for controlling the oil flow rate injected in a two-stroke internal combustion engine wherein oil is injected independently of fuel. The invention is characterised in that it consists in controlling the oil on the basis of a temperature representing the engine heat load. More precisely said temperature can be that of an element constituting the engine, such as a spark plug gasket.

摘要： The invention concerns a method for improving the pour-point of a feedstock containing paraffin of more than 10 carbon atoms, whereby the feedstock to be treated is contacted with a catalyst containing NU-86 zeolite and at least a hydro-dehydrogenizing element, at a temperature between 170 and 500 °C, pressure between 1 and 250 bars and a horary volume velocity between 0.05 and 100 h-1, in the presence of hydrogen at the rate of 50 to 2000 l/l of feedstock. For heavy feedstock, the resulting product is fractionated for producing at least a fraction containing at least a middle distillate with reduced pour-point, and a residue containing the oil bases with reduced pour-point and high viscosity index. Preferably the NU-86 zeolite is dealuminized.

摘要： The invention discloses a steam cracking installation and method with controlled injection of solid particles in a quenching exchanger (3). The particles are injected with a single axially injecting conduit located on the axis of the quenching exchanger feed hopper (2), immediately upstream of an impact separator-diffuser (6) comprising solid surfaces arranged opposite the conduit for the transfer of the cracked gases towards the exchanger; this impact separator-diffuser is located in the exchanger feed hopper (2), is permeable to gases by means of a plurality of passages, and has an opacity of at least 70 % as viewed from the transfer conduit.

摘要： The invention discloses a steam cracking installation comprising at least one multitubular quenching exchanger, equipped with a non-obstructing impact separator (6a, 6b) for preventing the erosion of the tubular input plate. This impact separator is at least 50 % opaque viewed from the transfer conduit (1). It is located inside a feed hopper (2), such that there is a free passage of at least 40 mm between the impact separator periphery and the hopper.

摘要： Cosmetic and dermatological composition comprising at least one unprocessed or acid sophorolipid or a sophorolipid associated with a monovalent or divalent salt in a concentration of 0.01-30 % by weight and use thereof. The composition is ideally in the form of a water in oil emulsion, an oil in water emulsion or an oil in water microemulsion. The sophorolipid-based compositions are useful as anti-free-radical, anti-elastasic and anti-inflammatory agents.
