Abstract

Ni-containing catalysts are obtained on the basis of carbon mineral supports produced using sapropel and studied during the catalytic hydroliquefaction of sapropel. It is found that catalysts on supports obtained from mineral-type sapropel are more active than ones on supports based on organic-type sapropel, while bimetallic NiW catalysts exhibit higher activity than monometallic nickel catalysts, regardless of the nature of the support. It is shown that both the nature of the deposited metal and the support composition affect the conversion of the organic matter of sapropel and the composition of liquid products. The liquid products of hydroliquefaction contain mainly nitrogen- and oxygen-containing compounds. The maximum yield of hydrocarbons C₅–C₂₁ is obtained for catalysts on supports obtained from mineral-type sapropel. Liquid products of hydroliquefaction of sapropels are similar in composition to biofuels from other renewable raw materials and can be included in existing schemes for further processing.

使用镍和镍-钨催化剂通过催化加氢液化合成液体燃料产品

摘要

含镍催化剂是在使用腐泥生产的碳矿物载体的基础上获得的，并在腐泥的催化加氢液化过程中进行了研究。发现从矿物型腐泥获得的载体上的催化剂比基于有机型腐泥的载体上的催化剂活性更高，而双金属 NiW 催化剂比单金属镍催化剂表现出更高的活性，无论载体的性质如何。结果表明，沉积金属的性质和载体组成都会影响腐泥有机物的转化率和液体产品的组成。加氢液化的液体产物主要含有含氮和含氧化合物。_{烃类 C 5} –C ₂₁的最大产率用于从矿物型腐泥获得的载体上的催化剂。腐泥加氢液化的液体产品在成分上与来自其他可再生原料的生物燃料相似，可以包含在现有的进一步加工方案中。
