The result shows that increasing water gas ratio, decreasing the temperature of hot point of the bed can lower the content of methane to avoid disadvantage influences out of by-reaction in methanation.
A new method of application of waste engine-oil producing emulsified oil for hot rolling process of steel plate was proposed. Performance of the product meets the request of the hot rolling process of steel plate.
In order to meet the requirement of rolling speed increase,heavy reducing in each stage,and severe demands for even better quality in terms of surface finish,a new hot rolling oil comprising a major proportion of semi-synthetic base oil and a 5%-15%(mass fraction) additive package has been developed for steel plates.
Petroleum olefins based raw materials are non-renewable resources,thus it becomes a hot topic of general interest by using abundant carbohydrate resource to replace petroleum for biology industry at home and abroad to produce synthetic chemicals,degradable materials and bioenergy.
