Title: Synthetic method under high pressure from reformed gas
Inventor: FUJITA TETSUO
IPC: C07C29/15
Filed: 1982-07-06
Abstract: PURPOSE:To carry out various synthetic reactions under high pressure in high conversion ratio, by adjusting the composition of a reformed gas with a gas separation membrane permeable selectively to hydrogen to give an optimal gas composition, and using the resultant gas as a raw material. CONSTITUTION:The pressure of a reformed gas obtained by the reforming reaction of a hydrocarbon with steam is boosted by a main compressor and reacted with a recycled gas (all or part of a separated gas obtained by separating a reaction product gas by the gas-liquid separation) in a high-pressure synthetic reaction system, and the product gas is separated into a gas and a liquid, which is then suitably post-treated. In the high-pressure synthesis, the reformed gas is brought into contact with a gas separation membrane permeable selectively to hydrogen gas, preferably a hollow membrane of cellulose acetate and polysulfonic acid type hollow membrane, and separated into a gas rich in hydrogen on the permeation side and the remaining gas on the unpermeation side, which is then subjected to the operation of the boosting and the operations thereafter. The method is applicable to the high-pressure reactions, e.g. synthesis of methanol, oxo synthesis, and synthetic reaction of ethylene glycol, etc.

Inventor: SHINDO YOSHIO
IPC: C25D13/20
Filed: 1987-05-13
Abstract: PURPOSE:To improve plating adhesiveness and performance after painting by subjecting a steel sheet successively to Fe, Ni and Co plating, composite Zn plating and further Fe alloy plating via a chemical conversion film. CONSTITUTION:This composite-layer plated steel sheet has, successively from the front, a 1st plating layer consisting of >=1 kinds among Fe, Ni and Co ad the 2nd plating layer consisting of Zn or Zn alloy contg. fine particles having <=5mu average grain size on at least one face thereof. The 3rd plating layer consisting of an Fe alloy is further provided on said layer via the chemical conversion film; for example, phosphate film. The 1st plating layer is required in order to enhance the adhesiveness of the 2nd plating layer with such composite-layer plated steel sheet but there is a need for relieving the impact force of chipping at a low temp. The formation of the 3rd plating layer is industrially best for the above-mentioned purpose; further, the chemical conversion film has the ability to slightly relieve the impact force. The impact force is greatly relieved if a phosphate film is formed as a subsurface treatment for painting in the 3rd plating layer.
