carbon-covered alumina carrier 氧化铝覆炭载体
Available standard MA-spinel bricks differ mainly in the type of magnesia and in the amount and type of their alumina carrier (sintered and fused MA-spinel, calc. alumina, white fused alumina, etc. )
目前各种标准的镁铝尖晶石砖主要在氧化镁的数量、种类和它们铝载体的种类（烧结和电熔镁尖晶石、钙，氧化铝，白电熔等）方面有很大的不同。
The said catalyst is prepared through mix shaping of zeolite with alumina to make up carrier, exchanging na ions in zeolite with ammonium ions, and impregnating with Pt.
该催化剂是将沸石与氧化铝先混合成型、制成载体，然后用铵离子将沸石中的钠离子交换至一定交换度，再用铂金属进行浸渍而制成的。
