20世纪后期，天然气勘探开发技术进步很快。发达国家中，天然气已逐步成为一种占主导地位的清洁能源。目前我国许多天然气化工企业面临天然气管网价格偏高、供应量不足和开工率下降等问题。新建的天然气化工厂，应考虑进入WTO后激烈的国际价格竞争。为解决上述问题，本文提出一种天然气和煤联合制备廉价合成气的新工艺，主要特点为利用廉价的煤，替代转化工艺中的燃料天然气，从而减少天然气的消耗量，降低合成气的生产成本。为减少煤造气设备设资（约占总投资的60%），核心设备可在退役高炉的基础上进行改造。这种新型合成气制备工艺对天然气价格有较强的弹性和适应性。 |

As a clean energy, natural gas has been widely used in many developed countries. However, a chemical plant with natural gas as its feed may be often disturbed by the high - cost and insufficient supply of natural gas, which may lead to a decrease of the operation period. To solve these problems, a new process for the preparation of low - cost synthesis gas from natural gas and coal is presented in this paper. Cheaper coal, which serves as a heating material and also a reactant, is fed into the furnace to partially substitute the expensive and largely consumed natural gas. In this way low - cost synthesis gas can be produced. To reduce the investment cost of the gasification unit of coal (about 60% of the total investment), the preparation furnace can be reconstructed on a small or medium blast furnace left unused in iron steel factories. This new process provides the flexibility to the price fluctuation of natural gas. |
