The result showed, in spite of its higher one-off investments and process cost, the economic benefit of residue hydrotreating-catalytic cracking combined process is still better due to its higher liquid yield and higher production value. Furthermore, the predominance of its product quality, product structure, environmental protection, etc., is very evident.

结果表明，渣油加氢－催化裂化组合工艺虽然一次性投资和加工费用较高，但由於其液体产品收率高、产值高，使之经济效益反而较好，而且组合工艺在产品结构、产品质量以及环保方面都具有明显的优势。

Therefore, we designed a porous effervescent atomizer. In this paper, experimental investigations have been conducted on the combustion characteristics of effervescent atomizers, and the experimental data could provide guidance for the designing of atomizers.
