Problems solved by technology

At present, the entrained bed gasification technology includes dry pressurized gasification technology and wet pressurized gasification technology. The dry gasification index is better and the cold gas efficiency is higher, but the equipment investment is huge, and there is no large-scale industrial production equipment Syngas experience, the shell dry gasification devices currently introduced in China are all in the exploratory stage

Abstract

The invention discloses a method for producing synthesis gas by using slurries containing hydrocarbon matter. The method comprises the following six parts of: the preparation of the slurries containing the hydrocarbon matter, the pressurization high-temperature gasification of slurries containing the hydrocarbon matter, the cooling and ash removal by bubbling water-bath temperature-reduction of high-temperature crude synthesis gas, the temperature-reduction dust removal and washing purification of the crude synthesis gas, the discharging of the crude ash, and the processing of the water containing fine ash. The method is not only applicable to the pressurization high-temperature gasification of solid-state or liquid-state hydrocarbon matter, but also applicable to the pressurization high-temperature gasification of the mixture of various solid-state and / or liquid-state hydrocarbon matters simultaneously. The method has good gasification index, simple device, less investment and convenient operation, is easy for upsizing, and has the positive effects of being wide in the applicable range of raw materials, being environment friendly and the like.

Description

【Technical field】 [0001] The present invention relates to a technical field of resource reuse, and more specifically, the present invention relates to a method for preparing synthesis gas by using hydrocarbon-containing solid and / or liquid substances. 【Background technique】 [0002] As we all know, energy is an important material basis for the survival of human society and to promote the sustainable development of society. Among the mineral energy reserves in the world, hydrocarbon-containing substances such as oil, natural gas and coal account for a considerable proportion. In my country's energy structure, coal accounts for about 70% (by weight), and realizing clean and efficient utilization of coal has great practical and strategic significance. Due to the relatively small oil resources in our country, the technology of coal liquefaction to oil belongs to the national key support technology, which has developed rapidly in recent years. At the same time, the conversion rat...
