    摘要: A method of vanillin production from ferulic acid with a high concentration by biotransformation using a Streptomyces sp. strain is claimed in this invention. This strain is named as Streptomyces sp. V-1, which has been deposited in China Center for Type Culture Collection on Jul. 12, 2006 with the number of CCTCC M 206065. Using this strain, high concentration of vanillin fermentation broth is obtained from ferulic acid by biotransformation in GY biotransformation medium. With the addition of macroporous adsorbent resin DM11, the concentration of vanillin can be greatly improved. The advantage of this invention is less environmental pollution, high product concentration, less by-product, short processing cycle, low production cost, simple product extraction, clean production process, product environmental friendly, safe and reliable, which solves many difficulties in the vanillin production from botanical raw material extraction or chemical synthesis, and therefore it has good application prospect.

    摘要: The invention relates to an ethylene cracking furnace having a multi-pass radiant coil, comprising at least one radiant section. In the radiant section there are provided with bottom burners and/or sidewall burners, and at least one set of multi-pass radiant coil longitudinally arranged in the radiant section. The multi-pass radiant coil is a four- to ten-pass type radiant coil. At least one tube of the multi-pass radiant coil is arranged to be spatially adjacent to a tube which is not consecutive to said at least one tube. With this arrangement, the thermal radiation influence between tubes with high temperature can be reduced, so that the tubes with low temperature can absorb the radiation heat from the tubes with high temperature. Therefore, the surface temperature of the tubes with high temperature can be reduced, thus extending the lifetime of the radiant coil and the operational cycle of the cracking furnace.
