此生产过程将带出两种有用的副产品：一是具有商业价值的聚合物高活性无机酸木质素；另外是用在染色和糖尿病患者食物中的木糖。
The process would produce two useful by-products: unsulphonated lignin, a commercially valuable polymer, and xylose, a type of wood sugar used in dyeing and in foods for diabetics.
标定结果表明，FC - 24催化剂具有较高的活性且稳定性好，产品选择性好，产气少、C5 +液收高。
The commercial trial results showed that FC-24 catalyst possessed stable high activity and good selectivity, thus the product slates were high in total C5 + liquid yield and low in gas yield.
镍系催化剂具有活性高、选择性好、产品分布可调、反应条件温和等优良性能。
Nickel-based catalysts possess high catalytic activity for ethylene oligomerization with high selectivity, easily-controlled oligomers distribution and moderate reaction conditions.
