For example, technology of multi-tube film sulfonation reactor and the reactor produced domestically; application of computer science in technology of sulfur trioxide sulfonation; product development of AOS and MES; manufacture of petroleum sulfonate and its use in tertiary process, etc.

Contrastive test was also performed in a glass tube film reactor.

In the SO3 sulfonation process,the high gas/liquid ratio jet reactor which was simple and compact in structure and stable in operation was applied as the sulfonaton apparatus,and the experiment gained a good result,the maximum conversion of ME is more than 95%,and that of SO3 is 99%,which is comparable with the result of film reactor.
