  • Patent number: 5804096
    Abstract: A first refrigerating machine oil of the present invention has a sodium and/or potassium concentration of not higher than 0.1 ppm. Since it has low hydrolyzability and excellent insulating properties, the first refrigerating machine oil is useful as a refrigerating machine oil composition for refrigerators having a hermetic compressor. A second refrigerating machine oil of the present invention is composed mainly of an ester of pentaerythritol and a carboxylic acid. The carboxylic acid is a mixed carboxylic acid composed of 3,5,5-trimethylhexanoic acid and a straight-chain or branched fatty acid having from 6 to 8 carbon atoms. The proportion of 3,5,5-trimethylhexanoic acid in the mixed carboxylic acid is in the range of from more than 50 mol % to not more than 90 mol %.

  • Patent number: 5582711
    Abstract: Disclosed is a catalytic cracking process which includes more than one catalytic cracking reaction step. The process integrates a hydroprocessing step between the catalytic cracking reaction steps in order to maximize olefins production, distillate quality and octane level of the overall cracked product. Preferably, the hydroprocessing step is included between the reaction stages, and a portion of the hydroprocessed products, i.e., a naphtha and mid distillate fraction, is combined with cracked product for further separation and hydroprocessing. It is also preferred that the first catalytic cracking reaction step be a short contact time reaction step.

  • Patent number: 5552119
    Abstract: A method and apparatus are described for contacting solid particles and fluid. A liquid is sprayed as liquid droplets from the discharge tip of a nozzle into hot solid particles passing upwardly in a vertical pipe. A venturi is formed in the pipe, and the venturi has an entrance portion which is upwardly convergent to the throat and an exit portion which is upwardly divergent from the throat. The tip of the nozzle is so located relative to the venturi that liquid droplets commence vaporization, due to heat transfer from the hot solid particles, no further up stream (relative to the direction of movement of solid particles up the pipe) than the throat of the venturi thereby resulting in a high degree of turbulence which causes good mixing of particles and vapor downstream of the venturi throat. The particles-vapor mixture leaving the exit portion of the venturi is well mixed and particles are substantially uniformly mixed with vapor in radial planes of the pipe downstream of the venturi.
