杏仁壳在流化床中的气化过程及产气特性的实验研究

Experimental Study on Gasification Process of Almond Putamina and Its Gas Performance in Fluidized Bed

在流化床气化炉内，以空气为气化剂，对美国杏仁壳在680℃、700℃、730℃和780℃的温度下进行了气化实验，生成的燃气成分为：CO含量在15．4％～18．7％之间，H2含量一般高于10％，甲烷含量为1.7％～2．5％，CnHm的含量为0．6％左右。燃气热值多数在4152．7kJ／m^3～4839．5kJ／m^3。气化效率51％。实验表明，在气化温度为700℃的时候可以得到最大的燃气热值。

Experiments on the gasification of the American almond putamina were conduced by using air as the gasification matter in the gasification stove of fluidized bed with the temperature 680 ℃, 700 ℃ ,730 ℃ and 780 ℃. The results are as follows： the resultant gas compositions are CO、H2、 CH4 and CnHm whose proportions separately are about 15.4% - 18.7% ,10% ,1. 7% - 2.5% and 0.6% ;The heating value of gas is from 4 152.7 to 4 839.5 kJ/m^3 ; the gasification efficiency is 51%. It is shown that we can gain the biggest heating value when the gasification temperature is 700 ℃.
