摘要
迈向21世纪的石油炼制技术的发展,除原油变重、增产中间馏分等市场因素的推动外,主要的推动力来自环境保护、保健和安全等日益严格的要求。 1 环境友好产品的生产 国外为保护环境,要求使汽油和柴油成为“环境友好”产品,对其质量制订了严格的规格指标。例如1990年美国清洁空气法(修正案)规定,将逐步推广使用含氧汽油(Oxyfuel)和新配方汽油(Reformulated Gasoline)。
Looking forward to the 21st century, the driving force for the development of petroleum refining technology mainly comes from the more stringent requirement of the environmental protection. For petroleum products, major progress will be made with technologies related to the production of environmental friendly products, such as reformulated gasoline and low sulfur and aromatics Diesel fuel. The solid acid catalysts to replace currently used liquid acid catalysts with environmental problems in the alkylation process are under expense study. Various means are sought to reduce the alkali waste. Continuous process advancement for improving the selectivity to produce more desired petroleum products is expected in catalytic cracking, hydrocracking and catalytic reforming.
