AI Technical Summary

Benefits of technology

The technical effect of this new process for making biological diesels from crude oils has been improved yields over previous methods due to its ability to convert all available triglycerides (fat) into usable products with high efficiency at lower costs compared to traditional processes like chemical catalysts or other techniques used by others during processing.

Problems solved by technology

The technical problem addressed in this patented text relates to finding better ways to stabilize certain types of biological reactions called enzymatically producing bimolectrolyte intermediately coupled enzymases while also reducing their negative effects upon other components like water quality and exhaustion. Existing methods involve adding large amounts of expensive materials at different stages of the synthesis processes, resulting in decreased yields due to decomposition caused by impurities within these compositions. To address this issue, there exists a demand for developing a more uniformly and durably methanoidium based catalyst activation technique.

Abstract

The invention discloses preparation of organic solvent slow release system and its application in enzyme catalysis reaction. It is formed by multi-hole solid matter and liquid state organic matter. The saturated solid matter reacts with vegetable oil under immobilization lipase and solvent at 30 centigrade degree for 12hr. Its product biological diesel oil yield can reach above 90%. Meanwhile the reclaimed immobilization lipase still holds high catalysis energy.
