Title: Method for converting olefin into gasoline
Inventor: MOOSEN NADEIMI HARANDEI
IPC: C10G35/095
Filed: 1989-12-22
Abstract: PURPOSE: To fractionate a stream of 3C, 5C-olefinic hydrocarbons in the presence of an intermediate pore shape-selective solid catalyst under oligomerization conditions to efficiently convert the lower olefins into 5C+ gasoline.  
     CONSTITUTION: (A) A hydrocarbon stream contg. 3C- and/or 4C-olefinic hydrocarbon is brought into contact with (B) an intermediate pore shape-selective solid catalyst under oligomerization conditions in an oligomerization zone to obtain an effluent rich in hydrocarbons in 5C+ gasoline range. The effluent is separated to obtain a 3C- hydrocarbon stream and a 3C+ hydrocarbon stream. The 3C+ hydrocarbon stream is fractionated to obtain a hydrocarbon stream in 5C+ gasoline range, a stream rich in 4C hydrocarbons and a stream rich in 3C hydrocarbons. Thus the starting lower olefinic hydrocarbons are converted into hydrocarbons in 5C+ gasoline range.

Filed: 1991-11-25
Abstract: PURPOSE:To surely detect the presence of a medium to be read without adoption of a picture read sensor with high sensitivity by arranging a picture pattern section drawn by the arrangement of plural colors while being opposite to a sensor face of the picture read sensor. CONSTITUTION:Picture data read by a picture sensor 2 are fetched by a detection circuit section 4e of a sensor control circuit 4a. The circuit section 4e compares picture data outputted from the sensor 2 with reference data stored in advance and the presence of a medium P to be read is decided based on the result. That is, when no medium P is in existence, since the picture read sensor reads a picture of the picture pattern section 3, the picture data outputted from the sensor 2 corresponds to the arrangement of the color from the picture pattern section 3. On the other hand, when the medium P is in existence, since the sensor 2 reads the picture of the medium P, the picture data outputted from the sensor 2 corresponds to the arrangement of the color of the medium P.
