The present invention relates to a process for producing hydrocarbons, said process comprising the steps, where feedstock of biological origin is degummed, the degummed feedstock is subjected to bleaching and/or hydrolysis, followed by hydroprocessing and catalytic cracking.

The invention belongs to the technical field of material chemistry and particularly relates to a method for preparing multilevel porous zeolite through microwave assisted decomposition of hydrogen peroxide. The method comprises the following steps: quickly decomposing hydrogen peroxide with certain concentration under the action of microwave radiation to generate a gas so as to produce instantaneous violent impact on zeolite to introduce secondary pores into beta zeolite. The method provided by the invention is simple in equipment, simple and convenient to operate and quick to react. The introduction of the secondary pores increases the specific surface area and the pore volume of the beta zeolite and reduces the crystal defects of the beta zeolite to ensure a more beautiful skeleton. The micro blasting pore-forming zeolite material has a huge application value in some macromolecular limited zeolite catalysis fields, for example, petroleum reforming, catalytic cracking and the like.
