The present invention relates to a heterogeneous catalysis process for synthesizing aldehydes and alcohols through olefin hydroformylation, and an apparatus thereof. More particularly, the present invention provides a heterogeneous catalysis method for synthesizing aldehydes and alcohols through olefin hydroformylation, wherein the method comprises that olefin and synthesis gas are continuously fed into a reactor to be in a hydroformylation reaction in the presence of a loaded heterogeneous catalyst, and the generated products such as aldehydes and alcohols continuously flow out from the reactor so as to achieve the separation from the catalyst and the continuous production. The present invention further provides the apparatus for the method, wherein the apparatus comprises the reactor, a pre-heater arranged on the upstream of the reactor and connected with the reactor, a mixer arranged on the upstream of the pre-heater and connected with the pre-heater, and a collecting tank arranged on downstream of the reactor and connected with the reactor. The process and the apparatus of the present invention have advantages of excellent hydroformylation performance, easy product and catalyst separation, and simple process, and further have industrial prospects.
